Re: [SR-Users] Wildcarded IMPU

Hello Maryam, (please keep the list in CC) understand. There is work ongoing to update the IMS modules (e.g. refer to https://www.kamailio.org/wiki/features/new-in-devel). I don't know about a current effort to add wildcarded AVPs to them, though. If you like to implement something in this regards, it is always good to announce it quickly on the developer list sr-dev to get some feedback and to to synchronize with other developers.

I read all ETSI‌ standards , latest version of standards are according to Release15 IMS but IMS modules in kamailio support Release 7 IMS. for example there is Wildcarded_IMPU AVP in AUR in R15 IMS which isn't implemented in IMS_icscf module in kamailio .

uac_replace_from() and multiple branches
by John Quick 16 Aug '19

16 Aug '19

v5.2.3 of Kamailio. Serial forking is used to route calls to a multiple destinations as described in documentation for the TM module. Also using the DIALOG module - my script calls dlg_manage() before loading the serialised branches. I need to be able to substitute the username part of the From header and have been trying this with calls to uac_replace_from(). modparam("uac", "restore_mode", "auto") modparam("uac", "restore_dlg", 1) There is no problem if all branches use one substituted From username, in which case my script calls uac_replace_from() in the main route. uac_replace_from("sip:" + $avp(route:src) + "@" + $fd); However, I may need to substitute a different value for each branch. Can this be done? I tried moving the call to uac_replace_from() into the branch route, but then I get an error when the final BYE is received: ERROR: uac [replace.c:281]: replace_uri(): decline FROM replacing in sequential request in auto mode (has TO tag) Is there a simple solution to this please? Hoping I can still use UAC auto restore mode because manual restore looks quite tedious/complex. Thanks. John Quick Smartvox Limited www.smartvox.co.uk

RFC 3860 support - Kamailio is sending SUBSCRIBE back with extra Via header
by Praveen Vatti 15 Aug '19

15 Aug '19

Hi Kamailio support, Basically, I am looking for RFC3860 support - i.e., accept SUBSCRIBE for reg event and send 200OK, NOTIFY to client. With some browsing on Internet I came across Kamailio, which is supporting RFC3860. I have installed and attached is my CFG file. I am sending a SUBSCRIBE request with reg event to Kamailio and it is sending back the same request with extra Via header. Via now contains Kamailio system IP and the source of SUBSCRIBE IP. Please help me in resolving this issue. I have loaded db_mysql, dialplan, tm, sl, presence, presence_reginfo modules. Thanks, Praveen

Uac_replace for header's parameters
by Duarte Rocha 14 Aug '19

14 Aug '19

Greetings, I'm using uac_replace_to() and uac_replace_from() to do some number manipulations. It allows me to modify and automatically restore Display Number and URI. This works nicely, however it only allows to manipulate URI's parameter. Is there any method to the same and include the Header's parameters too? Best regards, Duarte Rocha

Question regarding Dispatcher + ds_default_socket() modparam + Call-ID generation
by Joel Serrano 14 Aug '19

14 Aug '19

Hello, Simple doubt regarding dispatcher module when you have the ds_default_socket() modparam set: Say you have 2 kamailio boxes, active + passive, one shared IP via keepalived.... On the actrive node, you have dispatcher.send_ping to 1, and the passive has it set to 0. So far OK, only the active box is sending out probing OPTIONS requests, and it's using as outbound socket the virtual IP out of all the available ones (as defined with ds_default_socket() modparam) I have seen in a capture that the outbound OPTIONS look like: OPTIONS sip:190.14.203.219:5060 SIP/2.0 Via: SIP/2.0/UDP A.B.C.180 ;branch=z9hG4bK7abb.6fbaccc1000000000000000000000000.0 To: <sip:190.14.203.219:5060> From: <sip:dspinger@my.domain>;tag=e2bdd495733c59fd91487a137fccad4e-8a73 CSeq: 10 OPTIONS Call-ID: 2019f8491329c382-31419(a)A.B.C.181 Max-Forwards: 70 Content-Length: 0 A.B.C.180 -> VRRP A.B.C.181 -> Physical IP of the box My doubt is, shouldn't ds_default_socket also update the IP used to generate the Call-ID used in the OPTIONS request? Currently, I believe it's using the first defined listen= IP from config script as I switched the order the listen= are defined and I get the desired result: OPTIONS sip:186.188.220.174:5060 SIP/2.0 Via: SIP/2.0/UDP A.B.C.180 ;branch=z9hG4bKc97e.a8d9e1c2000000000000000000000000.0 To: <sip:186.188.220.174:5060> From: <sip:dspinger@my.domain>;tag=5e2e1773f812f6a7e4085c5d036e29d8-d323 CSeq: 10 OPTIONS Call-ID: 7d9a92c218fc1ba0-32111(a)A.B.C.180 Max-Forwards: 70 Content-Length: 0 Is this expected?

Kamailio/Freeswitch auth user and UserID
by Petarr Jones 14 Aug '19

14 Aug '19

Hi I am new to Kamailio and would like some guidance on linking up with Freeswitch. I have an exiting hosted Asterisk PBX that uses a combination of extension and pbx username (eg 1001-126252581276) and I want to move it over to Kamailio/Freeswitch without re-configuring the SIP phones. I have tried Freeswitch "number-alias" but it does not seem like a good fit due to things like BLF not working and the added overhead etc. Is there a way to configure Kamailio to authenticate a user based on the above username and then send an extension to Freeswitch as the UserID instead, thereby separating the Kamailio authentication from the Freeswitch UserID? As I don't yet have a full understanding of the Kamailio/Freeswitch interaction, I don't know whether this will cause other issues? Thanks in advance Petarr

Re: [SR-Users] Dispatcher round-robin problems in 5.2
by JR Richardson 14 Aug '19

14 Aug '19

Hey Alex, After I recently upgraded, I had to include more response codes, 5.2 by default only 200 OK is accepted. I had some upstream carriers sending 405 and were taken off-line as a result until I added that code in modparm: modparam("dispatcher", "ds_ping_reply_codes", "class=2;code=405") Not sure if this applies to what you are doing, but my dispatcher round robin distribution acts as it did prior to upgrade to 5.2, pretty even, no anomalies with any nodes getting more calls than any other. JR JR Richardson Engineering for the Masses Chasing the Azeotrope Hi, I've got a proxy that does very basic round-robin distribution of calls to an elastic pool of servers, defined in a simple SQLite database with equal priorities. Nothing too complicated, just a vanilla `ds_select_domain("1", "4")`. The only complication is that seldom are most of the gateways enabled. Probing stuff was turned on, but didn't do quite what was desired, so it was replaced with a system that manages activation and deactivation of the gateways externally. Nevertheless, these are the left-over probing settings: modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_ping_from", "sip:pinger@domain") modparam("dispatcher", "ds_ping_interval", 15) modparam("dispatcher", "ds_probing_threshold", 256) modparam("dispatcher", "ds_inactive_threshold", 1) modparam("dispatcher", "ds_probing_mode", 0) After an upgrade from 5.1 to 5.2.3 (009f62), the round-robin has become extremely "sticky" and tendentious. That is to say, it directs _almost_ all calls to a single gateway -- the first gateway in the table -- though not 100%. There is also a marked tendency to send lots of consecutive calls to the same gateway, even if it's not the first one, though most of the time it is. Has anyone experienced similar upon upgrading to 5.2? Thanks much! -- Alex

Wrong Record-Route and Via header fields when TCP is used
by Leonid Fainshtein 14 Aug '19

14 Aug '19

Hi, Kamailio server has two legs that are connected to different networks. I'm using Kamailio v.5.2.3 and the "enable_double_rr" is implicitly set to "1". The leg "A" IP address is 10.159.65.1 The leg "B" IP address is 192.168.0.31 The call is initiated from 10.159.65.18 According to the "rr" module documentation, function record_route() should insert two "Record_Route" header fields when a request is accepted on one leg is should go out via the second leg. This works as expected in case of UDP protocol: INVITE sip:2000@192.168.6.106:5460;transport=UDP SIP/2.0 Record-Route: <sip:192.168.0.31;r2=on;lr;did=e2c.a191> Record-Route: <sip:10.159.65.1;r2=on;lr;did=e2c.a191> Via: SIP/2.0/UDP 192.168.0.31;branch=z9hG4bKcfa5.d64ecbd87d5315b5993c4ccf16f86537.0 Via: SIP/2.0/UDP 10.159.65.18:5060;rport=5060;branch=z9hG4bK3a9e9a4d But when the TCP protocol is used then the outbound message looks like this: INVITE sip:2005@192.168.0.178:35058;transport=tcp SIP/2.0 Record-Route: <sip:10.159.65.1;transport=tcp;lr;did=bb6.7dc1> Via: SIP/2.0/TCP 10.159.65.1;branch=z9hG4bKc85a.14afc3867dd3220826f9b9940f78168f.0;i=3 Via: SIP/2.0/TCP 10.159.65.18:5060;rport=58616;branch=z9hG4bK1469331f There are two problems there: a) only one Record-Route with leg is inserted b) the added "Via" header field contains the leg "A" IP address instead of expected leg "B" IP address (192.168.0.31). In the LAN trace I see that in reality the message was sent from leg "B". Is it a bug? Best regards, Leonid Fainshtein

Strange behavior for unregister() function. Wrong docs? Bug?
by Joel Serrano 13 Aug '19

13 Aug '19

Hello, I'm playing around with the unregister() function from the registrar module: https://www.kamailio.org/docs/modules/devel/modules/registrar.html#registra… Docs say that that it can be used in REQUEST_ROUTE or FAILURE_ROUTE. I needed it in REPLY_ROUTE, and before reading the docs I tried it and got this error: Aug 12 15:52:44 csbc01 kamailio: CRITICAL: <core> [core/cfg.y:3526]: yyerror_at(): parse error in config file /etc/kamailio/csbc/reply_routes.cfg, line 27, column 71: Command cannot be used in the block#012 Aug 12 15:52:44 csbc01 kamailio[12737]: ERROR: bad config file (1 errors) But, I have this working on another setup, I compared, and my difference is that I'm running unregister() inside a route, and calling that route from reply_route, and that works (and by works, I mean it also does what it is supposed to do, which is unregister the AoR). So this doesn't work: ... onreply_route[MANAGE_REG_REPLY] { if(status=~"2[0-9][0-9]") { if(($sel(contact.expires)==0) || ($hdr(Expires)==0)){ if (unregister("location", "$sht(sipserver=>$fU::contact)")) { xlog("L_NOTICE", "[usrloc] removed user location\n"); } route(DEL_SIPSERVER); } ... But this works: ... onreply_route[MANAGE_REG_REPLY] { if(status=~"2[0-9][0-9]") { if(($sel(contact.expires)==0) || ($hdr(Expires)==0)){ route(UNREG_CUSTOMER); route(DEL_SIPSERVER); } ... ... route[UNREG_CUSTOMER] { if (unregister("location", "$sht(sipserver=>$fU::contact)")) { xlog("L_NOTICE", "[usrloc] removed user location\n"); } } ... So I'm in no-mans-land right now, docs say it's not allowed in REPLY_ROUTE, and if I try it it will fail, but if I try it inside a route, it woks (hack?). What is the correct approach here? Should unregister() be valid in reply_route (like other similar functions, for example: save()) and therefor docs should be updated and the error in the logs should also be updated, or if it's really not supported, shouldn't Kamailio not let me use it anywhere that a ends up being called from reply_route? I hope I have explained myself correctly. As always, please let me know if this should be a GH issue instead and I'll happily create it. Thanks, Joel.

Kamailio DRA - Unable to get diameter_request() function to send
by Nick Jones 10 Aug '19

10 Aug '19

Hi Kamailio users, I'm trying to setup Kamailio as a Diameter Routing Agent, but I just can't seem to get the diameter_request() function to actually send a diameter request, I just get a warning about no JSON Response: *WARNING: ims_diameter_server [avp_helper.c:341]: addAVPsfromJSON(): No JSON Response* Inside my event route I've got one line to send the data to the peer "ims-hss.localdomain": *event_route[diameter:request]{ diameter_request("ims-hss.localdomain", $diameter_application, $diameter_command, $diameter_request); xlog("Forwarded Diameter Request");}* Hard as I try I can't seem to get this request forwarded to this peer and see that next xlog() line. In the config file I've included the cdp_check_peer & cdp_has_app checks to confirm the peer is up, and able to accept the request, (full config in pastebin below) I've defined the peers in the diametercfg.xml config file, and they're all showing as online when I do a "kamcmd cdp.list_peers": * FQDN: ims-hss.localdomain Details: { State: I_Open Disabled: False Last used: 0 Applications: { appid:vendorid: 16777216:10415 appid:vendorid: 16777216:4491 appid:vendorid: 16777216:13019 appid:vendorid: 16777216:0 appid:vendorid: 16777217:10415 appid:vendorid: 16777221:10415 } }* The source of avp_helper.c shows the warning is called if the length of the JSON is <= 0, but as I'm feeding back out what I've received it's not 0, an no recent major changes to the source, so I'm stumped as to why it's catching this.

kamailio as UAC and NAPTR / sendsocket question
by Karsten Horsmann 09 Aug '19

09 Aug '19

Hi List, I try to register to Deutsche Telekom and there product Deutschland Lan siptrunk. Thats works find but i see an intressting behaviour on selecting the right outgoing interface. Kamailio is sending out with tcp the REQUEST via first private ip configured on that server (172.20.120.53). There is no listen directive for that. I forced NAPTR to use tcp or udp and i assume that kamailio got the right dns answers. On the list i read also that i can use force_send_socket to force the outgoing request. Now my idea - hey i use the $rP for the outgoing to select the right outgoing listen directive. $rP - reference to transport protocol of R-URI But to my surprise the logfile told me thats "UDP" - it sends out via TCP (thats okay). Whats an good transport selector variable from kamailio that works? event_route[tm:local-request] { if(!is_method("OPTIONS")) { xlog("L_INFO", "[tm:local-request] request [$rm] from [$fu] to [$ru] [$rP]\n"); } } INFO: <script>: [tm:local-request] request [REGISTER] from [ sip:+49XXXXXXXX@sip-trunk.telekom.de] to [sip:sip-trunk.telekom.de] [UDP] listen=tcp:2xx.xx.xx.xx:5060 listen=udp:2xx.xx.xx.xx:5060 listen=tls:2xx.xx.xx.xx:5061 advertise CFG_EXT_NAME:5061 listen=udp:172.20.120.55:5060 listen=udp:172.20.120.56:5060 listen=udp:172.20.120.57:5060 listen=udp:172.20.120.58:5060 listen=tcp:172.20.120.58:5060 use_dns_cache=on # use internal DNS cache use_dns_failover=on # depends on internal DNS cache dns_srv_loadbalancing=on dns_try_naptr=on dns_retr_time=1 # seconds before retrying a DNS request dns_retr_no=3 # number of DNS retransmissions dns_naptr_ignore_rfc=yes # ignore target NAPTR priority dns_tcp_pref=30 # TCP has second-highest priority dns_udp_pref=10 # use UDP with least priority tcp_connection_lifetime=3605 # set higher than registration expires #dont' restore modparam("uac","restore_mode","none") modparam("uac","restore_dlg",0) ## UAC REGISTER #!ifdef WITH_UAC_REGISTER modparam("uac", "reg_contact_addr", "CFG_PROD_IP") modparam("uac", "reg_timer_interval", 10) modparam("uac", "reg_retry_interval", 10) modparam("uac", "reg_db_url", DBURL) modparam("uac", "restore_mode", "none") modparam("uac", "auth_username_avp", "$avp(AVP_AUTH_USERNAME)") modparam("uac", "auth_password_avp", "$avp(AVP_AUTH_PASSWORD)") modparam("uac", "auth_realm_avp", "$avp(AVP_AUTH_REALM)") #!endif ip a l 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens192: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:50:56:b5:c1:48 brd ff:ff:ff:ff:ff:ff inet 172.20.120.53/24 brd 172.20.120.255 scope global ens192 valid_lft forever preferred_lft forever inet 2xx.xx.xx.xx/29 scope global ens192 valid_lft forever preferred_lft forever inet 172.20.120.56/24 scope global secondary ens192 valid_lft forever preferred_lft forever inet 172.20.120.57/24 scope global secondary ens192 valid_lft forever preferred_lft forever inet 172.20.120.58/24 scope global secondary ens192 valid_lft forever preferred_lft forever inet 172.20.120.55/24 brd 172.20.120.255 scope global secondary ens192 valid_lft forever preferred_lft forever inet6 fe80::250:56ff:feb5:c148/64 scope link valid_lft forever preferred_lft forever default via 172.20.120.253 dev ens192 172.20.120.0/24 dev ens192 proto kernel scope link src 172.20.120.53 2xx.xx.xx.xx/29 dev ens192 proto kernel scope link src 2xx.xx.xx.xx -- Kind Regards Mit freundlichen Grüßen *Karsten Horsmann*

XMLRPC request URL
by David Villasmil 08 Aug '19

08 Aug '19

Hello guys, I can't find any reference to a pseudovariable containing the request url, i.e.: http://myserver/XMLRPC?server=1.2.3.4 I'd like to get that server variable and manipulate the dispatcher list... the http client can't do XMLRPC or add a body, just an https request.. Any ideas? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Breaking HTABLE changes from v5.2 to v5.3? Function renamed
by Joel Serrano 08 Aug '19

08 Aug '19

Hi all, Just noticed that when updating from 5.2 to 5.3 I saw some errors in Kam logfile regarding HTABLE module commands failing, the reason is the function 'sht_has_name' has been renamed to 'sht_match_name': https://www.kamailio.org/docs/modules/stable/modules/htable.html#htable.f.s… https://www.kamailio.org/docs/modules/devel/modules/htable.html#htable.f.sh… Not sure if updating this doc is automatic or manual but I think it's definitely worth mentioning: https://www.kamailio.org/wiki/install/upgrade/stable-to-devel Just FYI! Cheers, Joel.

Reload geoip2 database without restart
by Joel Serrano 07 Aug '19

07 Aug '19

Hi guys, Is there a way to instruct the geoip2 module to reload its database without a full restart of kamailio? Maybe some rpc command or something? I haven't found anything in the docs other than the comment about "Database is loaded at startup in cache." which makes me assume that just overwriting the db file wouldn't be enough. Any suggestions? Thanks!! Joel.

Sipt redirection number retrieves old values
by Duarte Rocha 07 Aug '19

07 Aug '19

Greetings, I'm doing VoiceMail detection using $sipt(redirection_number) from SIPT module and i've been having some false positives on the detection. I inspected further and noticed that in some cases $sipt(redirection_number) returns old values from previous messages, which makes me think that it's value is not being correctly refreshed. I'm using this variable on a on_reply_route. As far as i know, $sipt(redirection_number) is read only and can't be refreshed by me in the code. Here is an example : Aug 7 16:51:49 dev_sbc_a_vts01 /usr/local/kamailio-5.2/sbin/kamailio[4746]: ERROR: <script>: VMD2 : Reply Code : 180 ; Sipt Redir = 9610050000 and Call ID = 00158FED-98B7-E911-8B3B-4DA50AE2ED72(a)192.168.24.86 and Cseq = 83 Here is the JSON from the 180 message : https://pastebin.com/zFHKxyav As you can see, there isn't any 9610050000 in the message. What can be causing this issue ? Best Regards, Duarte Rocha

app_ruby - invalid ruby environment attributes or parameters
by Andrew White 07 Aug '19

07 Aug '19

Hey all, I’m setting up a dev-7 (bd477f) server to test as per the other thread, however I’m getting the following loading my config: ERROR: app_ruby [app_ruby_api.c:465]: sr_kemi_ruby_exec_func_ex(): invalid ruby environment attributes or parameters I’m unsure what this error means - are there expected environment variables or other values that must be set? I didn’t see this issue in dev-4. I thought it might be not able to find the library, but I ran with debug=4 and saw: DEBUG: app_ruby [app_ruby_api.c:193]: ruby_sr_init_child(): test execution without error ERROR: app_ruby [app_ruby_api.c:107]: app_ruby_print_last_exception(): exception: undefined method `>' for false:FalseClass I changed kamailio.cfg to load my generic routing script, and during the onreply_manage it runs: scode = KSR::PV.get("$rs”) This now returns false (which appears to be the second error above, I check if scode is > 599). Has anything changed in the way ruby is loaded in dev-7? I’m using the same ruby/ruby-devel library versions on the same OS. I did this deploy the same with devel-4 a few weeks ago and this didn’t happen. Thanks! Andrew

The domain module in 5.1.8 has a memory leak
by Mack Hendricks 06 Aug '19

06 Aug '19

Based on my tests, the memory leak is only exposed when you are using domain attributes, which are stored in the domain_attrs table. I wanted to see if anymore else is running into this issue. *Reproducible use case:* 1) Insert the following into the database insert into domain values (null,"aprilco.com","aprilco.com",now()); insert into domain_attrs values (null,"aprilco.com","pbx_type",0,"0",now()); insert into domain_attrs values (null,"aprilco.com","pbx_id",0,"65",now()); 2) Open a new terminal window and execute: watch "kamcmd core.shmmem" 3) Open up another terminal windows and execute: while true; do kamcmd domain.reload; done *Expected Results:* You will see the shared memory being allocated, but never freed. The more entries you have in the domain_attrs table, the faster it will run out of memory.

Error Registering the user and finding the AVP
by jespinosa 06 Aug '19

06 Aug '19

Hello, My name is Javier, I must first apologize for my little knowledge about the tool and my poor English. I am trying to connect a functional core network LTE with Kamailio and I have used the Polaris Networks Solution that brings an iso with both functionalities. The EPC is correctly configured and working because I can have data connection in my UE, I have also activated all the IMS options in the EPC: I have created the APN with ims identifier, the default carrier QCI assigned is 5 (for SIP signaling), the MME has activated the option to support IMS Voice over the PS session and the HSS and PCRF nodes are configured with the interfaces at the addresses and ports Cx-HSS 127.0.0.1:3868 and Cx-PCRF 10.11.0.35:3868 . There are several parameters that I do not know if it is necessary to activate, for example, in the PCRF the customization of the QCI for the media type, if I must include the OCS and OFCS as nodes, or if in the profile of my APN I must include authentication by PDN AAA. The configuration I use for the IMS is as follows: imsrealm = net1.test imsport = 5060 pcscfgmip = 10.77.0.35 pcscfgmipintf = eth6 pcscfrxip = 10.102.81.111 pcscfrxipintf = eth1 icscfmwip = 127.0.0.21 icscfmwipintf = lo:21 icscfcxip = 127.0.0.20 icscfcxipintf = lo:20 scscfmwip = 127.0.0.23 scscfmwipintf = lo:23 scscfcxip = 127.0.0.22 scscfcxipintf = lo:22 audiobandwidth = 64 videobandwidth = 128 epcrealm = epc.mnc001.mcc001.3gppnetwork.org pcrfhost = pcrf2.morsecore pcrfrxip = 10.11.0.35 pcrfrxport = 3868 hsshost = hss6.morsecore hsscxdxip = 127.0.0.1 hsscxdxport = 3868 Both cores are running on the same machine but I have disabled the option of PCRF Co-located with IMS to be able to edit the pcrf host name since if I enable it it does not reach the peer pcrf.localhost even if the DNS is well configured. My UE is not able to launch the REGISTER by itself when it is going to make a call, so I am using the Google IMSDroid application to be able to launch the SIP requests and check the operation of the IMS.

Re: [SR-Users] Kamailio v5.2 kamctl alias add problem
by Igor Potjevlesch 04 Aug '19

04 Aug '19

Hi kamailio Users, I meet a problem with the " kamctl alias add" command in the 5.2 version, I saw that the module used to add an alias had changed, and now the command result with an error : [kamailio]# kamctl alias add XXXX@XXXX sip:XXXXX@XXXX { "jsonrpc": "2.0", "error": { "code": 500, "message": "Not enough parameters or wrong format" }, "id": XXXXX } So in the version 5.2, the table aliasdb replace the table alias ? We are using the table alias for the incomming call, and we implemented scripts to add with the command kamctl alias add the information needed in the tavble alias to route the call. But since the version 5.2 we need to add an argument "path" in this command, and we don't know how to put it at "NULL" or how we can use this argument ? Can you help us with this?

Hey all, looking for a little help. I've been tracking an issue, where a number of SIP Messages ( typically INVITE ) are sent, but Kamailio only see one of them ( the last one). I have verified that the messages are definitely received on the host, as verified with TCPDUMP, but the INVITES never hit the request route block. ( the very first thing is to log the message ) What i've managed to find is, that if I increase worker children, the problem goes away. So I've got a problem, I think I've found the solution, but what I'm struggling with is how to monitor better, so I can be alerted to this in the future. I started by looking at "kamctl stats | grep drop" "core:drop_replies = 14", "core:drop_requests = 10577" however drop_requests seems to include explicit drops in my config. which I do for many reasons, but mainly bad UA or blocked IP's, so this dosnt seem to be what im after. I then went digging in the code ( often the best way to find things ). in receive.c receive_msg() we find some conditions, where we drop the packet ( before calling request route ). right now im looking around line 251 at LM_DBG("dropping the received message\n"); goto error00; Following error00 I see it calls STATS_RX_DROPS which increments stats->received_drops. This is where it gets fun, I cant find where received_drops is ever returned in the stats output. I can see where -SIGUSR1 will trigger this to be dumped, if Kamailio is compiled with that option ( dosnt seem the debian packages are ). however, what im seeking clarification on is, does this get reported in "kamctl stats" Am I just going crazy or is something not quite right here? TLDNR; how do I monitor for Kamailio not having enough worker threads to process incoming messages. FYI I'm seeing about 50Mbps of incoming SIP on this box, and I do perform a decent amount of work on some message types. -- Sincerely Jay

Deleting extra location attribute(location_attrs table) when contact is expired
by Pintu Lohar 31 Jul '19

31 Jul '19

Hi All, Regarding modparam("tm|usrloc", "xavp_contact", "ulattrs") #ref : https://www.kamailio.org/docs/modules/devel/modules/usrloc.html#usrloc.p.xa… . There is some requirement where we need to save some extra location attributes to location_attrs <https://kamailio.org/docs/db-tables/kamailio-db-4.3.x.html#gen-db-location-…> tables $xavp(ulattrs=>deviceIdentify)= "Some str values" and calling save(“location”) , It works well and saved location attribute table but But when contact expired callback is received, udomain_contact_expired_db() does not it delete the extra location attribute from database but deleting the record from location table only ? If not, is there any recommended approach to delete the extra location attributes from the database? or am I missing something to set? Alternate I was thinking could be running timer from Kamailio config and check last_modified time and delete those(based on our UAC expiry setting), is it the right approach. Kamailio Version: 5.2.0. Thanks for your valuable suggestion in advance. Regards Pintu Lohar

Hello, I would like to know if it is possible to enable registration for users that have not been created with kamctl.

Dialog missing when BYE is received from trunk
by Andrew White 28 Jul '19

28 Jul '19

Hi all, I’ve got a call flow where PBX makes a call via Kamailio, which uses the UAC modules to make the call to the trunk. This works great, however I’ve noticed recently that when the BYE comes from the trunk, Kamailio doesn’t recognise the dialog and throws back a 404. Due to this, the PBX never knows the session has ended, and keeps its session open. Here’s the flow from Wireshark: https://i.imgur.com/BxPRrXP.png <https://i.imgur.com/BxPRrXP.png> As you can see, the BYE is received from the trunk, and Kamailio throws a 404. I checked with an rpc dlg.list and at this point the dialog had gone. 30 seconds later, I threw a BYE from the PBX, and because the dialog no longer existed, it got a 481 back. The INVITE to the trunk has the following Record-Route header: Record-Route: <sip:kamailio.public-ip;lr;ftag=mjKtcKaBteQ4Q;vst=AAAAAAYFBQUHAwYHBgRzMwIRGRMcAgJBWBEVCwAbBhtADxBjdGVkLmNvbS5hdQ--;did=624.b2e1> When the first BYE comes in, it still has same did in the Route header. Below I’ve put the output from the dialog list rpc call (before the first BYE) and the relevant log lines. { h_entry: 1062 h_id: 7723 ref: 2 call-id: a9d32620-2b68-1238-048a-0cc47a18705a from_uri: sip:61400123123@pbx.local:5060 to_uri: sip:61400123123@10.0.0.2 state: 4 start_ts: 1564269942 init_ts: 1564269929 end_ts: 0 timeout: 1564313142 lifetime: 43200 dflags: 643 sflags: 0 iflags: 16 caller: { tag: mjKtcKaBteQ4Q contact: sip:pbx.local cseq: 7581172 route_set: socket: udp:10.0.0.2:5060 } callee: { tag: SD5ptp899-1177933201-1564269931305 contact: sip:SDd3mt8-nn9jnirnmqcrvfmvkpm0hmhvgggjgv2io788of70s84u9@trunk.remote:5060;transport=udp cseq: 0 route_set: socket: udp:10.0.0.2:5060 } profiles: { } variables: { { cseq_diff: 1 } } } Jul 28 09:27:30 ip-10-0-0-2 /usr/local/sbin/kamailio[11061]: NOTICE: {2 450917085 BYE a9d32620-2b68-1238-048a-0cc47a18705a} acc [acc.c:279]: acc_log_request(): ACC: transaction answered: timestamp=1564270050;method=BYE;from_tag=SD5ptp899-1177933201-1564269931305;to_tag=mjKtcKaBteQ4Q;call_id=a9d32620-2b68-1238-048a-0cc47a18705a;code=404;reason=Not here;src_user=0400123123;src_domain=trunk.remote;src_ip=trunk.remote;dst_ouser=0400123123;dst_user=0400123123;dst_domain=kamailio.public-ip I’m assuming the 404 is because the Contact header I sent from Kamailio -> Trunk is rewritten, that Contact is Kamailio’s public contact IP. However the dialog has the caller contact within it referencing back to the local PBX, so I would think when Kamailio gets this dialog ID back with a BYE it would relay it back to the original contact, wouldn’t it? Thanks! Andrew

Hi all, I read some portion of imc_isc_mod.c, specially isc_from_as function. In that function there is some function call that searching for some marks in the SIP message. Also I read section 5.7.3 from TS 24.229 but I didn't find the marking mechanism that used in isc_from_as function. Would you please point me to the technical specification that implemented in IMS_ISC module? Regards, Ali

Concatenating strings in $hdr

Hello, I'm having an issue where this doesn't work: #!trydef PRODUCT "Foo" if( $hdr("X-" + PRODUCT + "-Transport") != "" ) { add_uri_param( $hdr("X-" + PRODUCT + "-Transport") ); } It seems Kamailio doesn't like the concatenation within the $hdr(). Concatenation does work in other places though: append_hf( "X-" + PRODUCT + "-Transport: tcp\r\n" ); Can anyone advise how to make the concatenation within $hdr() work?

Malformed Route Header
by Duarte Rocha 25 Jul '19

25 Jul '19

Greetings, When a in-dialog request has Route headers, Kamailio will remove the Route Header with it's address when routing the packet. This works perfectly for me in every situation. However, in one of the calls I found a weird behaviour in the removal. So, this is the scenario : Kamailio has two IP's 1.1.1.209 and 1.1.1.205. This is BYE request received in the on 1.1.1.209 The header Route looks like this when it arrives at 1.1.1.209 : Route : <sip:1.1.1.209;r2=on;lr;ftag=5AE0303037363132017D0E65;tbk_i=2_2_Y;tbk_o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQECA3ByAwMcHwIdHQsWHwUMOA--;vst=AAAAABgHDQgBAwsIBQECdnIDAxwfAh0aBB4cAgU5;did=8f5.67c2>,<sip:1.1.1.205;r2=on;lr;ftag=5AE0303037363132017D0E65;tbk_i=2_2_Y;tbk_o=128_11_Y;vsf=AAAAABgGBAMDAAUBBQECA3ByAwMcHwIdHQsWHwUMOA--;vst=AAAAABgHDQgBAwsIBQECdnIDAxwfAh0aBB4cAgU5;did=8f5.67c2> It reaches 1.1.1.205 like this : Route : As you can see, the header is empty and it should contain the 1.1.1.205 URI. Is the header Router malformatted and creating this error ? Best Regards, Duarte Rocha

Re: [SR-Users] [EXT] Re: P-CSCF and I-CSCF ports -RESOLVED
by Woscek, Martin W. 24 Jul '19

24 Jul '19

Hi Ali, Looking through the source code, its not that the port for I-CSCF is hard coded to 5060, its just that it defaults to 5060 if the following is set in the Kamailio.cfg file: dns_try_naptr=no which we had left it disabled. Well I assumed I had all the DNS worked out, I had NAPTR records set for the P,I and S-CSCF. Looking though the pcscf.cfg there is a setting for NETWORKNAME which is set to ims522.ims.org, and is a separate FQDN from the P,I,S-cscf FQDN’s. I always kept the NAPTR rec for ims522 as the same port of the P-CSCF (pcscf522) in DNS. Two things I needed to fix: 1. Enable the DNS NAPTR lookups: dns_try_naptr=yes 2. Modify the NAPR for ims522 to be that of 4060 Thanks to you and Amar for the pointing to DNS. _Martin From: sr-users <sr-users-bounces(a)lists.kamailio.org> On Behalf Of Ali Shirvani Sent: Tuesday, July 23, 2019 1:40 PM To: Kamailio (SER) - Users Mailing List <sr-users(a)lists.kamailio.org> Subject: [EXT] Re: [SR-Users] P-CSCF and I-CSCF ports Hi Martin, As Amar pointed out it may some DNS configuration.

kamailio 4.4.4 fills IPv6 contact address when sending packet over IPv4
by Pali Rohár 24 Jul '19

24 Jul '19

Hi! I detected strange problem that sip.linphone.org refuse to accept presence information re-transmitted by kamailio 4.4.4 server. I debug this problem with tcpdump and I found out that problem is in kamailio which fills IPv6 address into UDP datagram and that datagram is sent via IPv4 socket to IPv4 address, to sip.linphone.org server. And sip.linphone.org server does not have IPv6 connectivity, so correctly return over IPv4 to sender just "400 Bad Contact Header" error. On my server is running kamailio 4.4.4 from Debian Stretch and I can 100% reproduce this problem against public sip.linphone.org server. My server has both IPv4 and IPv6 connectivity and kamailio is listening for both IPv4 and IPv6 connections. So why is kamailio sending IPv6 address over IPv4 and therefore makes it impossible to communicate with non-IPv6 enabled servers? Looks like a problem with choosing default/correct socket for Contact header. And how to fix this problem? Can you help me? I would like to have working interconnection with linphone servers. Just to note I'm seeing this problem only for presence information packets. Other requests, like INVITE or MESSAGE seems to work. Below is relevant tcpdump output. Some parts were replaced by {VAR}. PS: I'm not subscribed to list, so please CC my address when sending reply.

How to hook to Register And Unregister event in Kamailio

Hi, I am integrating Kamailio into my application. I want to hook to the successful REGISTER and unregister event into Kamailio into my application. For now, I am able to hook into INVITE event and can hit my server to send a email to the callee user that user X is calling you. The way I am doing is by this if (is_method("INVITE")) { xlog("LOG_LOCAL3","L_INFO","invite came ($fU) ($tU)"); $var(res) = http_connect("sipnodejsserver", "/","text/plain","src_user:$fU,dst_user:$tU" ,"$avp(route)"); xlog("LOG_LOCAL3","L_INFO","request sent $avp(route) $var(res)"); setflag(FLT_ACC); # do accounting } I need to show into my application that their SIP phone is online or not. How can I hook into this?

Debugging kamailio module
by Ali Shirvani 23 Jul '19

23 Jul '19

Hi all, I want to trace function calls in a kamailio module, e.g. ims_isc module. I installed kamailio-dbg package and started the kamailio with gdb: `gdb kamailio` I also set break point on target function, but it seems gdb doesn't stop on that break point. How should I start gdb and set break points? it seems gdb couldn't handle kamailio child processes that forked in start. Regards, Ali

Two GWs with the same IP
by Duarte Rocha 22 Jul '19

22 Jul '19

Greetings, I'm building some testing procedures for my Kamailio proxy. In order to do that i have a SipTester (Acting as Calling Number) from where i want to originate calls to Kamailio. After Kamailio processes the call, i want it to route it to SipTester again so it can act as Called Number. This should work with only one SipTester in one machine, so i created two SipTester GW's on Kamailio, belonging to different users and GW groups. Also, the two GWs use different Kamailio addresses to communicate with the proxy. However, in this combination, when routing i get this error " ERROR: dialog [dlg_handlers.c:666]: pre_match_parse(): bad request or missing CALLID/TO hdr :-/". If i change the destination or the origin of the INVITE the calls work without a problem. Does this happen because both GW's have the same address? Best Regards

Reading presence state
by Gertjan Wolzak 19 Jul '19

19 Jul '19

Hello Kamailions, I have been able to get the presence configured, subscribers see the status of their subscriptions, this is working fine, for internal, incoming external and external calls. This was solved by enabling use_pubruri_avps in the pua_dialoginfo module. Now I want to be able to route calls based on the presence state. Using the presentity table could be used by doing a query based on the userpart of the ruri, which works fine when the call is still active, but it can take a while for the record to be removed from the presentity table, as that is dependend on the expires value. So when a query is made after a call is finished, a record would still be present in the presentity table till clean_period timer has hit again and the expires value is expired. So I should get the status from memory, but I have not been able to find the information on how to do that. Can someone enlighten me on where to find that information? Rgds, Gertjan

Kamailio IMS to IP PBX - how?
by David Dean 16 Jul '19

16 Jul '19

I'm trying to connect a VoLTE smartphone to an IP PBX using Kamailio IMS. I've managed to get the smartphone to connect to Kamailio IMS and make calls with our devices registered with Kamailio. The problem is that I need the smartphones to register with the IP PBX which is a VigorBX 2000n. This is so they can use an internal extension number and make calls to other local extensions with hard wired desk phones. Should I be using Kamailio IMS to "proxy" the smartphone SIP connection to the VigorBX PBX? Or would it be better to connect the smartphone directly to the VigorBX using SIP? If so, how? I've read absolutely every how-to document I could lay my hands on but none of them describe integrating IMS with a PBX. Thanks for any help / advice you can offer. Dave

How to get total number of dialogs in profile with value
by Nathan Angelacos 15 Jul '19

15 Jul '19

In kamailio < 5.1.x it used to be possible to get total number of items in a dialog_with_profile by skipping the "value" paramter, such as: modparam ( "dialog", "profiles_with_value", "outbound" ) . . . get_profile_size ( "outbound", "$var(myvar)" ); However, 5.1.x and 5.2.x report: ERROR: dialog [dialog.c:912]: w_get_profile_size_helper(): invalid value parameter The documentation ( https://kamailio.org/docs/modules/5.2.x/modules/dialog.html#dialog.f.get_pr… ) Indicates the "value" paramter is still optional. I'm sure I must be missing something obvious... Any ideas? Thanks!

UDP fragmentation issues
by Gerry | x164 15 Jul '19

15 Jul '19

Hi, I have setup Kamailio on Centos 7 as a proxy in front of Asterisk in the same datacenter, using the dispatcher module. I have noted that large INVITEs sent by Kamailio do not arrive at the Asterisk box. It seems the network is dropping fragmented UDP traffic. This does not happen however when I contact the Asterisk box directly from outside the datacenter. Then large INVITES are arriving are Asterisk. So the problem is either in Kamailio or in the datacenter. I have analysed the problem with ngrep and tcpdump/wireshark. In normal mode (udp4_raw=no setting) Kamailio is producing UDP packets above 1500 bytes and leaves all fragmentation to the operating system. Enabling raw udp in Kamailio and lowering the MTU in the server didnt help. I even disabled offloading of UDP fragmentation to the NIC to get to the bottom of this. However nothing helps. Only forcing TCP in the dispatcher works when having large INVITES going to Asterisk. In any case, it appears that there is no guarantee that fragmented UDP arrives at all. As far as I am aware, the recommendation is to use TCP if messages are bigger than 1400 bytes. If so, how can I force Kamailio to send messages over 1400 bytes only in TCP mode? Or is there some other way how to deal with this? Thanks for any hints. Gerry

Kamailio Asterisk integration with docker DNS Problem
by Amir 15 Jul '19

15 Jul '19

Hi I have created a kamailio container with docker and two asterisk container And this is my dispatcher list: *1 sip:asterisk:50601 sip:asterisk2:5060* and this is my both asterisk SIP.conf *[Kamailio]host=kamailioport=5060insecure=invitetype=friendcontext=from-internal* The problem is that I use User-defined networks which has its own DNS when a container starts a dns record would be set If I start a kamailio first then start two asterisks the asterisk works fine because the name "kamailio" has been set in docker dns but I should restart the kamailio because at startup It could not resolve astersik dns records after the everything works fine but if the any of the asterisk instances crash/stop kamailio can not detect that because a dns record would not be available: *17(22) ERROR: <core> [core/resolve.c:1684]: sip_hostport2su(): could not resolve hostname: "asterisk2"17(22) ERROR: tm [ut.h:309]: uri2dst2(): failed to resolve "asterisk2"17(22) ERROR: tm [uac.c:452]: t_uac_prepare(): no socket found17(22) ERROR: dispatcher [dispatch.c:3110]: ds_ping_set(): unable to ping [sip:asterisk2:5060]* It is kind of loop , I think maybe I can fix asterisk problem with asterisk realtime and set the sip.conf in database. anyone has any suggestion for this problem?

Wrong $rm value

14 Jul '19

Hello list, I use kamailio 5.2.3 from repo's on stretch in docker. I use python KEMI + async and encountered weird behaviour: after t_continue $rm shows OPTIONS instead of REGISTER/INVITE. I wonder if that's correct behaviour, because for me it looks like a bug. Repeating is easy - just check $rm after t_continue. ________________________________ Regards, Alexandru Covalschi VoIP Engineer and System Administrator tel: +37367367850

Check if an INVITE comes from uac_reg endpoint

14 Jul '19

Hello Kamailio experts, We were already able to register correctly at a SIP Provider using uacreg table. Now, we would like to validate inbound calls coming from this registered provider, sending them to a specific dispatcher group. I tried reading the uac module docs, found *uac_reg_lookup* function, but i'm not sure if that's we need. Could someone please help me to understand if UAC has a function to do that, or if we need to make some? Thanks!!

Long distance rtpengine communication

Hi all, We have kamailio servers which communicate with the geographically distributed rtpengine servers. Sometimes udp packets are lost or delayed between kamailio and rtpengine. And this causes call drops... Since rtpengine communication is synchronized and tcp worker processes are blocked, I couldn't set higher timeout values and more retry count. Are there any suggestions to overcome this problem? Thanks, Koray

SIP URI Evaluation and Forwarding
by Ronald Hartmann 12 Jul '19

12 Jul '19

Good Day List, I am very new to Kamailio and trying to understand at 10,000 feet how it may be able to be used. I was wondering if the following Scenario would be possible and if so what modules would accomplish this aspect. (Any URLs for further reading would be appreciated) Scenario: Given 1) SoftPhones will register as follows sip uri, user(a)subdomain.myvoipserver.com 2) The following users are authorized to connect (this would be stored in a config file etc): 1001,1003,1007 are valid users for apples.myvoipserver.com 1001,2213,5817 are valid users for oranges.myvoipserver.com Is it possible for Kamailio to perform the following evaluation and then take the appropriate steps: If [domain is apples.myvoipserver.com AND user portion is 1001] then Forward/Proxy the SIP/RTP packets to Asterisk server responsible for registration and audio for the domain apples.myvoipserver.com Else if [domain is oranges.myvoipserver.com AND user portion is 2213] then Forward/Proxy the SIP/RTP packets to Asterisk server responsible for registration and audio for the domain oranges.myvoipserver.com Else Silently Drop packets etc. given the above evaluation rules, a user who tries to register as 1001(a)apples.myvoipserver.com would be granted access and their SIP Packets and subsequent RTP would be forwarded to the asterisk server at apples.myvoipserver.com, where said server would take care of the Registration, and any subsequent calls, subscriptions, Options etc. 1004@ apples.myvoipserver.com Would not match the authorized list for apples.myvoipserver.com (1001,1003,1007), therefore this registration attempt would be silently dropped 2213(a)apples.myvoipserver.com would be granted access and their SIP Packets and subsequent RTP would be forwarded to the asterisk server at oranges.myvoipserver.com, where said server would take care of the Registration, and any subsequent calls, subscriptions, Options etc. Thanks for any information to assist me in understanding how this would work. ~ron

Hello Ali, (please keep the sr-users list in CC, that other people can also participate) Remove the “-D” from your Kamailio command line – then the warning will disappear. This is also necessary because you want to have Kamailio listen on several addresses. If you want to test it more in a production like setting, you should also remove the “-E” from the command line. You will find the logging in your system log then.

Hello, Could someone help me to set a variable as a string in Kamailio? At the moment i'm using the following statement: *$var(account)=$(au{s.substr,0,8}); * *xlogl("L_INFO", "[1234] Account: $var(* *account* *)\n");* which is working fine, but i need to change it into: *$var(account)=$(au{s.select,0,-}{s.toupper})-$(au{s.select,1,-});* By doing this I'm getting the error: *[core/rvalue.c:1007]: rval_get_int(): automatic string to int conversion for "AT" failed[core/rvalue.c:1912]: rval_expr_eval_int(): rval expression conversion to int failed (729,30-729,59)* I tried also: *$var(account)="" + "$(au{s.select,0,-}{s.toupper})-$(au{s.select,1,-})";* But, then I'm getting: *Account = $(au{s.select,0,-}{s.toupper})-$(au{s.select,1,-})* instead of the value. What is the correct way to set it? Thank you.

kamctl ul command seems NOK when using an IPv6 Address
by Albert Petit 09 Jul '19

09 Jul '19

Hi, I am trying to create an identity with permanent location in my system using kamctl ul add command. Usually i have no issue doing that in IPv4 ,example kamctl ul add mcpttcontrolling sip:mcpttcontrolling@127.0.0.1:5070 it is OK However when i do that using an IPv6 address i get following error: kamctl ul add mcpttcontrolling sip:mcpttcontrolling@ [2001:470:1f21:219:20c:29ff:fedb:db6e]:5070 error: invalid SIP URI: sip:mcpttcontrolling@ [2001:470:1f21:219:20c:29ff:fedb:db6e]:5070 Let me know what you would need to investigate or what i am doing wrong for adding a location with IPv6 Address using kamctl tool Thanks Albert

How to statelessly send a reply to custom destination?
by George Diamantopoulos 05 Jul '19

05 Jul '19

Hello all, I've been trying to handle OPTIONS statelessly, but proper handling fails for UACs behind NAT without ALG. I thought I'd overcome this by setting the $du pseudovariable, but apparently I'm missing something. The following does not work: if ($Rp == "6050") { force_send_socket(udp:10.10.10.10:6050); } $du = "sip:" + $si + ":" + $sp; sl_send_reply("200","OK"); exit; I'm now realising that I put this in request_route() so force_send_socket() and $du have no use whatsoever, since the request is not forwarded anywhere. Is this the reason? So the question is, how can I do the following things for a stateless reply: a) choose a sending socket for the reply and b) change the destination for the reply to something other than the URI in the first Via header. Thanks! BR, George

Append a new branch while the other one is in ringing state
by Koray Vatansever 04 Jul '19

04 Jul '19

Hi all, I want to fork a new branch, while the first one is ringing. Forking will take place in a rtimer process. So I will save the invite transaction in a htable, and using this transaction info I need to append a branch. I saw TSILO module provides some methods to append branch. However documentation says that it can be used when register message received. What is the best way to implement this? Thanks, Koray

people complain Kamailio not handling stale nonce correctly
by Juha Heinanen 03 Jul '19

03 Jul '19

Several people are complaining on baresip git that Kamailio is among those SIP servers that don't handle stale nonce properly, i.e., don't include stale=true flag in WWW-Authenticate header of 401 response. I have tried to tell that Kamailio does what it has been configured to do, but the response is that "by default" Kamailio works incorrectly. "By default" I guess refers to the example Kamailio kamailio.cfg in etc dir. How about adding stale nonce handling to the example config, for example, like in below? -- Juha *** kamailio.cfg 2019-06-13 17:17:17.182148989 +0300 --- /tmp/kamailio.cfg 2019-07-02 18:02:02.947183503 +0300 *************** *** 745,753 **** if (is_method("REGISTER") || from_uri==myself) { # authenticate requests ! if (!auth_check("$fd", "subscriber", "1")) { ! auth_challenge("$fd", "0"); ! exit; } # user authenticated - remove auth header if(!is_method("REGISTER|PUBLISH")) --- 745,759 ---- if (is_method("REGISTER") || from_uri==myself) { # authenticate requests ! switch (auth_check("$fd", "subscriber", "1")) { ! case 1: ! break; ! case -4: ! auth_challenge("$fd", 17); ! exit; ! default: ! auth_challenge("$fd", "0"); ! exit; } # user authenticated - remove auth header if(!is_method("REGISTER|PUBLISH"))

DMQ: dmq_t_replicate()
by Lars Olsson 02 Jul '19

02 Jul '19

Hi, I am trying to replicate a REGISTER request between several nodes. When I am using dmq_t_replicate(), it ends the execution of the script. It this correct or I have missed anything? I can not find anything in the documentation of the DMQ module the says that it will end the script execution. Is it recommended to use the DMQ module or should I simply forward the request instead as described in https://medium.com/@tumalevich/kamailio-registration-replication-without-dm… Best Regards, Lars

[DMQ] Sync DLG_STATE_CONFIRMED_NA dialog state ?
by Mathieu Bodjikian 02 Jul '19

02 Jul '19

Hello, We are using DMQ module to sync dialogs between 3 Kamailio boxes. We are using last Kamailio version (5.2.3). >From our understanding, the state DLG_STATE_CONFIRMED_NA is not synced over DMQ (https://github.com/kamailio/kamailio/blob/a84a3ea618f0e602a8892c37fce7f4e72…) With containerized environement, the ACK's can go to any Kamailio instance, which lead to : On first box : -> INVITE received -> Dialog created + KDMQ sent (state DLG_STATE_UNCONFIRMED) -> 180 | 183 received -> Dialog updated + KDMQ sent (state DLG_STATE_EARLY) -> 200 received -> Dialog updated + KDMQ NOT sent (DLG_STATE_CONFIRMED_NA) On second box : -> ACK received : - next_state_dlg(): bogus event 6 in state 2 for dlg - dialog not updated - KDMQ with state DLG_STATE_CONFIRMED not sent On first box, after timeout : -> After timeout : - dialg with incorrect timeouts (since box2 didn't send dialog update) - tm sends BYE in both ways - bye_reply_cb(): inconsitent dlg timer data on dlg We see two solutions : - We add DLG_STATE_CONFIRMED_NA to states we sync on dlg_dmq_replicate_action - We manage to route the ACK on the same instance that received first INVITE (could be tricky) Which one is preferable ? Kind regards, Mathieu Bodjikian

question about reply route
by Iván Aponte 02 Jul '19

02 Jul '19

Hello, I have a question about record route and via headers. My scenario is the following: [asterisk] ---- [kam] -------- [trunk] 10.142.0.27 10.142.0.6 200.x.x.x I have an asterisk an a kamailio in a private ip network (10.142.0.0/24). Kamailio has the address 10.142.0.6 but is also natted 1:1 to a public ip (35.0.0.6). My problem is that when the invite are replied the asterisk replies to the external ip (35.0.0.6) instead of the internal ip (even though the kamailio replies goes through the internal network) . I tried adding a reply route to change the advertised address to no avail. any advice would be appreciated. this is my conf: LISTEN="listen=udp:0.0.0.0:5060 advertise 35.0.0.6:5060" disable_tcp=yes loadmodule "jsonrpcs.so" loadmodule "kex.so" loadmodule "corex.so" loadmodule "tm.so" loadmodule "tmx.so" loadmodule "sl.so" loadmodule "rr.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "textops.so" loadmodule "siputils.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "ctl.so" loadmodule "cfg_rpc.so" loadmodule "acc.so" loadmodule "counters.so" loadmodule "permissions.so" loadmodule "ipops.so" modparam("jsonrpcs", "pretty_format", 1) modparam("tm", "failure_reply_mode", 3) modparam("tm", "fr_timer", 30000) modparam("tm", "fr_inv_timer", 120000) modparam("rr", "enable_full_lr", 0) modparam("rr", "append_fromtag", 0) reply_route { xinfo("source $si"); if(!is_in_subnet($si, "10.0.0.0/8")) { set_advertised_address("10.142.0.6"); } else { xinfo("not in subnet"); } } request_route { # per request initial checks route(REQINIT); # CANCEL processing if (is_method("CANCEL")) { if (t_check_trans()) { route(RELAY); } exit; } # handle retransmissions if (!is_method("ACK")) { if(t_precheck_trans()) { t_check_trans(); exit; } t_check_trans(); } # handle requests within SIP dialogs route(WITHINDLG); ### only initial requests (no To tag) # authentication #route(AUTH); # record routing for dialog forming requests (in case they are routed) # - remove preloaded route headers remove_hf("Route"); if (is_method("INVITE|SUBSCRIBE")) { record_route(); } # dispatch requests to foreign domains route(SIPOUT); if ($rU==$null) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } } # Wrapper for relaying requests route[RELAY] { if (!t_relay()) { sl_reply_error(); } exit; } # Per SIP request initial checks route[REQINIT] { if($ua =~ "friendly-scanner|sipcli|VaxSIPUserAgent") { # silent drop for scanners - uncomment next line if want to reply # sl_send_reply("200", "OK"); exit; } if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; } if(is_method("OPTIONS") && uri==myself && $rU==$null) { sl_send_reply("200","Keepalive"); exit; } if(!sanity_check("1511", "7")) { xlog("Malformed SIP message from $si:$sp\n"); exit; } } # Handle requests within SIP dialogs route[WITHINDLG] { if (!has_totag()) return; # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { if ( is_method("NOTIFY") ) { record_route(); } route(RELAY); exit; } if (is_method("SUBSCRIBE") && uri == myself) { send_reply("405", "Method Not Allowed"); exit; } if ( is_method("ACK") ) { if ( t_check_trans() ) { # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server route(RELAY); exit; } else { # ACK without matching transaction ... ignore and discard exit; } } sl_send_reply("404","Not here"); exit; } route[SIPOUT] { if (uri==myself) return; append_hf("P-hint: outbound\r\n"); route(RELAY); exit; } -- Iván Aponte Office: +58(212)9923193 Mobile: +58(412)2774713

Late offer ACKs not passing through branch_route
by Bandiera, Enrico 01 Jul '19

01 Jul '19

Hi, I'm encountering an issue when relaying late offer ACKs, before relaying I set the branch_route with t_on_branch() but kamailio never enters that route after calling t_relay I'm keeping the rtpengine module calls inside branch_routes to avoid issues when re-routing in failure routes I suppose it's something related to ACK packets but I'm not sure what the issue is. Any hints? Thanks, Enrico.

Kamailio 5.x and Call_control module
by Efelin Novak 30 Jun '19

30 Jun '19

Hi Folks, I'm migrating to Kamailio 5.2.x from 4.4.x. Everything seems to be fine, however I have came to an issue with call_control module as this one is still using old MI interface. Standard situations work nice (maximum debit, prepaid, "CDRs") however when call_control needs to kill a call (credit is gone), it tries to send dlg_end_dlg over MI and it fails. Question are: Is call_control still supported? I haven't found any note about it. Is there any workaround from Kamailio point of view? I'm running last versions of both applications. I'm also rising a ticket at ag-projects side. Thanks Efelin

Htable not reloading from db on expiry
by Daniel Greenwald 28 Jun '19

28 Jun '19

I have an htable that loads from mysql. The data loads fine on startup but disappears on expiry. If I issue kamcmd htable.reload it loads again until expiry. It seems as if db_expires is not taking affect. I see them expiring in the debug log but not an errors. Mysql general log does not show any attempt to connect on expiry. Another odd thing is that if I set the expires column in db to anything other than 0 the data doesn't load at all. Any ideas would be appreciated. modparam("htable", "timer_interval", 10) modparam("htable", "htable", "h=>size=20;autoexpire=20;dbtable=validdomains;updateexpire=0;") modparam("htable", "db_url", AUTHDBURL) modparam("htable", "db_expires", 1) create or replace view validdomains as select distinct subscriber.domain as key_name, 1 as key_value, 0 as key_type, 0 as value_type, 0 as expires from subscriber;

What else is strange is that the dialog continued on with that same SIP Call-ID. This is what it looks like in the wireshark flow diagram: [image: image.png] The dispatcher entry is an SRV record which lists available hosts. Any thoughts on how I can identify the cause of this?

Topos / Remove HF_re
by Nicolas Breuer 27 Jun '19

27 Jun '19

Hello, When using TOPOS module, Kamailio add this header : P-SR-XBranch before executing the topos module. Doing this "remove_hf_re("P-")" in the scripting seems to bypass the addition of the P-SR-XBranch in the sip message. In my mind, remove header function just remove the headers based on the incoming message. What do you think ?

Question about registrar behavior
by Lars Olsson 27 Jun '19

27 Jun '19

Hi, I have found a behavior in the registrar module that I do have a question about. Is the current behavior correct and wanted? Using the save() method in the script I see the following: * Processing a register request for a user gives return code 1 ( or 2 ) * Processing a unregister request (expires=0) for registered user gives return code 3 * Processing a unregister request (expires=0) for a user which is NOT registered gives return code 1. Why? What is the reason behind this? No database entry is added which is expected. Test performed on 5.1.4, using DB mode 3. For handling a late unregister request ( where registration has already expired) return code does not reflect the the action. I assume that manually checking $expires(max) is the option to go then if I want to detect the unregister request or? Cheers, Lars

Presence publish manipulation
by Gertjan Wolzak 26 Jun '19

26 Jun '19

Hello Kamailions, I'm running into the following challenge. A kamailio setup where phones register with their mac address as uid and a password. Users have to login to the system by dialing a special number where they have to enter their internal extension and a pin code. Now the system knows which extension(number) is logged in on which phone(macaddress). This is done with from updates, just a type of hotdesking. Now I want to use presence.... When a phone makes a phone call, kamailio generates a publish message where the "local" part of the xml code contains the mac address. How can I manipulate the Publish xml information? I mean the manipulation can be done with textops, but which variables to use and where in the configuration? Im asking because when I disable the presence route and do not call it in my configuration, but with presence enabled, I still get Publish messages.... I have tried adding a Sender header which contains the "extension" of the phone and then call the publish in the PRESENCE route like this: handle_publish("$hdr(Sender)"); But this does not change the xml information. Am I doing things wrong? Below the first publish message that is send, where 10.88.77.172 is the kamailio server.

TOPOS uid in contact param instead of username
by Thomas Weber 26 Jun '19

26 Jun '19

Hello, we're using topos/redis since some time and it's working quite well for most situations. It's used to route asterisk traffic to sip providers. Some providers, however, are validating the contact header strictly against i.e. the accounts username and so we have to disable topos by using event_route[topos:msg-sending]. Now i'm wondering if it would be useful to other people to add a mode to topos where the topos uid is not forwarded as contact username but instead added as a contact uri param. So instead of e.g. Contact: <sip:btpsh-5abcdef5-374-1@x.x.x.x:5060;transport=tcp> it would use Contact: <sip:+49......@x.x.x.x:5060;transport=tcp;line=btpsh-5abcdef5-374-1>. What do you think? Would it make sense? Is it a lot of effort? Cheers, Thomas

Kamailio routing BYE back to originator
by Andrew White 24 Jun '19

24 Jun '19

Hi team! I’ve recently found an issue in my Kamailio setup. It appears when the trunk replies to call in progress with a BYE, we relay it immediately back to them: https://i.imgur.com/h5fusau.png <https://i.imgur.com/h5fusau.png> The only differences in the second BYE is the Route header is removed and replaced with a Via header referencing the Kamailio machine, and the From URI is rewritten to show the Kamailio hostname. I’m unsure what steps I can take here, as all of my out of dialog messages (180, 200, ACK) are forwarded along with no issue. It seems only the in dialog are having this issue. Here’s my WITHINDLG and RELAY: def ksr_route_relay() if KSR.is_method_in("IBSU") then if KSR::TM.t_is_set("branch_route") < 0 then KSR::TM.t_on_branch("ksr_branch_manage") end end if KSR.is_method_in("ISU") then if KSR::TM.t_is_set("onreply_route") < 0 then KSR::TM.t_on_reply("ksr_onreply_manage") end #KSR.info("Onreply route: #{KSR::TM.t_is_set("onreply_route")}") end if KSR.is_INVITE() then if KSR::TM.t_is_set("failure_route") < 0 then KSR::TM.t_on_failure("ksr_failure_manage") end end if KSR::TM.t_relay() < 0 then KSR::SL.sl_reply_error() end exit end def ksr_route_withindlg() return if KSR::SIPUTILS.has_totag() < 0 if KSR::RR.loose_route() > 0 then ksr_route_dlguri() if KSR.is_BYE() then #KSR.setflag($myenv['FLT_ACC'].to_i) #KSR.setflag($myenv['FLT_ACCFAILED'].to_i) elsif KSR.is_ACK() then ksr_route_natmanage() elsif KSR.is_NOTIFY() then KSR::RR.record_route() end ksr_route_relay() exit end if KSR.is_ACK() then #KSR.info("Handling an ACK within dialog") if KSR::TM.t_check_trans() > 0 then ksr_route_relay() exit else exit end end #KSR.info("404ing within dialog") KSR::SL.sl_send_reply(404, "Not here"); exit end I suspect I must be sending this to the wrong branch somehow, but I’m unsure how to correct this. The call gets originally initiated from Kamailio writing a custom RURI and To header before calling t_relay(). I’m wondering if I’m somehow initiating the dialog incorrectly and as such the BYE doesn’t know where to go. Thanks! Andrew

XMPP
by David Villasmil 19 Jun '19

19 Jun '19

Hello guys, I'm kind of confused as to what module exactly i need to user, let me explain: I have a service for DIDs and SMS from s.ms, i created a python script that connects to the service using xmpp to their jabber server with a user and a password, i.e.: xmpp_client.py MY-NUMBER(a)s.ms MY-PASSWORD What i do with that script is basically connect and wait to receive SMS, which i then insert in the proxy db (silo) and they get delivered by msilo. I have several numbers and doing this for every number seems stupid, so i started looking for a better solution, since the end user will be receive the message via SIP MESSAGE on they sip client. i came across kamailio/opensips' jabber and xmpp modules, but i'm not sure which (if any) to use, and even HOW to, or the actual architecture, since the documentation keeps talking about a local xmpp server? I would REALLY appreciate some help here. Thanks!

Hey All, I'm doing some upgrades and noticed database table version numbers have increased. database table adjustments: | address | production ver 3 | upgrade 5.2 ver 6 | need to add accountcode and notes column | dispatcher | production ver 3 | upgrade 5.2 ver 4 | need to add attr column | trusted | production ver 5 | upgrade 5.2 ver 6 | need to add ruri_pattern and priority column I run mysql master/slave so I'm concerned about the master database not having the correct version numbers or can I just update the version number in the table when I do the upgrade of the kamailio versions?

Kamailio Crashing when using Evapi with CGRateS
by Efelin Novak 18 Jun '19

18 Jun '19

Hi folks, I am doing some experiments with Kamailio and Cgrates. To be precise I am testing evapi module. When in testing environment I do not have any problem. After redirecting some production traffic to this kamailio, It crashes in at random times (few minutes to 20). I didn't find any pattern here. CGRateS doesn't write anything in logs. I'm on the last 4.4 Kamailio (compiled recently). CGRateS is on the last version. Can you please point to how to continue with debugging?

Modify DMQ 200OK in on_reply route
by jenus＠cyberchaos.nl 18 Jun '19

18 Jun '19

Hi all, I'm trying to run a kamailio DMQ node inside a docker container. All works fine but i have one issue with DMQ. Since the kamailio process inside the container is behind a nat i have set the advertise address to the external ip, this works fine for the via headers but DMQ keeps sending the internal interface in the KDMQ notification_peer messages. The external ip is in there as well. Example: SIP/2.0 200 OK Via: SIP/2.0/UDP 10.10.10.13;branch=z9hG4bK2dcb.c6326de2000000000000000000000000.0 To: <sip:notification_peer@10.10.10.94:5060>;tag=616b7acb681ed5e9cbc485b3faa09d62.0a3d From: <sip:notification_peer@10.10.10.13:5060>;tag=e8f29c06c4b85a188f6533f08d60feb6-ff29 CSeq: 10 KDMQ Call-ID: 17042656602ca532-23367(a)x.x.x.x Content-Type: text/plain Server: kamailio (5.1.4 (x86_64/linux)) Content-Length: 222 sip:10.10.10.13:5060;status=active sip:10.10.10.12:5060;status=active sip:10.10.10.92:5060;status=active sip:10.10.10.93:5060;status=active sip:10.10.10.94:5060;status=active <-- entry for container external ip sip:172.17.0.2:5060;status=disabled <-- entry for container internal ip I tried to strip this entry using the replace_body_atonce in the tm:local-request route. This works fine for the KDMQ request, but when i try to remove the same line from 200OK responses that are send out as a response to incomming KDMQ messages this seems to fail. I use the following code: # Working code (for outgoing KDMQ requests): event_route [tm:local-request] { if(is_method("KDMQ") && $rU == "notification_peer") replace_body_atonce("sip:172.17.0.*:5060;status=.*", ""); } # Failing code (for 200OK responses): reply_route { xlog("L_ALERT", "REPLY: Sending out reply, tU is $tU rs is $rs\n"); if ($rs == "200" && $tU == "notification_peer") { replace_body_atonce("sip:172.17.0.*:5060;status=.*", ""); } } I'm running kamailio 5.1.4. Is there a way to strip a line from the body of a local generated 200OK response? Or is there a way to avoid that DMQ inserts the internal container ip in the first place. Thanks, Jan Hazenberg

Rabbitmq module blocks sip request
by Denys Pozniak 18 Jun '19

18 Jun '19

Hello! I use rabbitmq module to get destination IP for the next call routing, but this module blocks sip request in case of RabbitMQ server is unreachable (timeout_sec/usec does not run out here). - Is there any solution to avoid such behavior and force function rabbitmq_publish_consume() to return an error code and continue script execution? - Is this connected with the nature of rabbitmq-c client? ("Currently librabbitmq offers no async API, but sync API, with a timeout.") -- BR, Denys Pozniak

Info: Kamailio.org - Infrastructure Maintenance - June 18, 2019
by Daniel-Constantin Mierla 18 Jun '19

18 Jun '19

The infrastructure hosting the main server for Kamailio project will go under scheduled maintenance during June 18, 2019 (tomorrow). The work is expected to start around 7:00am UTC and can last for a few hours. During the maintenance interval, the services related to Kamailio project may become unavailable, among them: * the web server (www.kamailio.org), including the wiki portal (www.kamailio.org/wiki) * the mailing lists and the email contact addresses * the GIT repository mirror git.kamailio.org Once the maintenance work is completed, there will be an update notification sent about it! If there are relevant events to be notified, we are going to publish on our twitter stream: * https://twitter.com/kamailio Also, you can join #kamailio channel on irc.freenode.net in case you want to report some incident related to our infrastructure that you discover while maintenance goes on.

Forward calls between kamailio registrar nodes (dmq + dmq_usrloc)
by Ildar Mukhametzhanov 18 Jun '19

18 Jun '19

Hello! I am developing setup with several kamailio nodes as registrar cluster (dmq + dmq_usrloc). Location sync works, I see locations of both servers on every server. Is there any standard approach to redirect call between nodes except replacing of $ru? Executing of lookup("location") for user registered on another node return negative response. -- Sincerely, *Ildar Mukhametzhanov* Head of software development VoiceON Telecom Services GmbH im(a)voice-on.net <mailto:im@voice-on.net> t. +49 30 398 20 500-77

Authenticating xhttp request
by Olli Attila 18 Jun '19

18 Jun '19

Hello, I have this xhttp event_route on Kamailio that I am using to signal the proxy to reload dialplans and htable when necessary: event_route[xhttp:request] { if(src_ip!=127.0.0.1) { xhttp_reply("403", "Forbidden", "text/html", "<html><body>Not allowed from $si</body></html>"); exit; } if ($hu =~ "^/RPC") { jsonrpc_dispatch(); } else { xhttp_reply("200", "OK", "text/html", "<html><body>Wrong URL $hu</body></html>"); } return; } Now instead of returning 403 forbidden for requests coming from other src_ip than proxy itsef, I would like to authenticate the http request via proxy database. How can this be done if possible? Cheers, Olli

dispatcher and TLS targets
by Karsten Horsmann 17 Jun '19

17 Jun '19

Hi all, i try to configure an SBC OS config [1] based kamailio 5.2.3 [2] with dispatcher and rtpengine. I used transport=tcp to see the plain traffic and then switched to TLS (with tls.cfg, valid certificate and stuff). After starting up, the Target is marked as "down". Due the encryption its hard to debug that. Any hints? Did i made an mistake in the configuration? TLS calls from the target to my kamailio proxy works. So its "half broken" :) at the moment.

Dispatcher's probing malfunction
by Duarte Rocha 17 Jun '19

17 Jun '19

Greetings, I have some questions about dispatcher's probing mechanics : 1 - In my SBC i have 26 gateways being probed. However, if i do a SIP capture no more than 16 gateways are probed each minute. Some gateways are always probed, others only once in a while. 2 - I have two SBC working in a pair with DB being replicated and with HA IPs. That being said i configure one NAP twice, each configuration with one HA socket. Is this configuration supported? I get very weird behaviours when i configure it like this. Best Regards, Duarte Rocha

Querying in-memory location table (dmq_usrloc)
by Gholamreza Sabery 16 Jun '19

16 Jun '19

I am using dmq_usrloc, to replicate user locations across multiple Kamailio instances. Everything works fine. The problem occurs when a user on Kam1 wants to call a user on Kam2. How can I query the in-memory location table to see where the user is registered? PS: I use a Path header to specify the server that each user is registered on.

Getting which timer has expired
by Igor Olhovskiy 14 Jun '19

14 Jun '19

Hi! Is there any way to get which timer on transaction actually expired? Scenario is following: INVITE - 180 - 200 OK - (restransmissions 250 msec starts) - pause 15 sec - ACK. In INVITE i'm setting t_on_reply("MY_REPLY") But in around 10 sec after first 200 OK (and 12 sec after INVITE) I'm getting in logs DEBUG: tm [h_table.c:133]: free_cell_helper(): freeing transaction 0x7fb632d77090 from timer.c:689 and on next 200 OK I'm never getting into onreply_route[MY_REPLY] again. Nowhere in the code or config I have explicit set any of timers with 10 or 12 seconds value. Most of them are default. So, can I somehow get which timer expired exactly?

Hello, I am new to Kamailio and I am using Kamailio 5.2. When trying to the load the XHTTP module, event route not found error is thrown and XHTTP is module is not getting loaded. I am trying to use JSONRPC module through HTTP transport for RPC calls. Using XMLRPC, things work fine.

S-CSCF replies “Forbidden - Domain not served”
by Bao, Yin 13 Jun '19

13 Jun '19

We have configured Kamailio IMS (P, I, S-CSCF) to use a single realm with the same NETWORKNAME and trying to make a call between bob and alice. We are getting S-CSCF replies “Forbidden – Domain not served” in two scenarios: 1. When bob calls alice, the INVITE went from P->S->I->S and the destination S-CSCF responded this error 2. During SIP registration in responding to SUBSCRIBE (endpoint still can register even with this reply, so we proceeded with making call) In quick search we found that in scscf/kamailio.cfg route{ } implementation there is a case when this error is generated: # Terminating if (uri == myself || uri =~ "tel:.*") { if (!term_impu_registered("location")) { xlog("L_DBG", "We need to do an UNREG server SAR assignemnt"); assign_server_unreg("UNREG_SAR_REPLY", "location", "term"); exit; } } else { sl_send_reply("403","Forbidden - Domain not served"); exit(); } route(term); break; What is this error designed for? Also in general are we supposed to rework the routing code in Kamailio.cfg (P, S, I-CSCF)? Thanks for any suggestions in advance. Yin

dialog:end event route
by Igor Olhovskiy 13 Jun '19

Hi! Just to confirm, is event route [dialog:end] not called on fr_inv_timer expiry? Cause it's called on call busy (486) and reject (whatever 6xx). So, what's the idea of not calling it on timeout? Or I'm missing something? Kamailio 5.2 Thanks! Regards, Igor.

TCP reset behavior
by R, Rajkumar (Raj) 12 Jun '19

12 Jun '19

Hi All, In our setup running kamailio (alpine image) in stateless mode and have following TCP config set. After client registers to the backend see two TCP connections created - one towards the client and the other towards the backendserver. If there's a abrupt network disconnect either at the client side or at the backend side, do not see TCP reset happening from kamailio as per the config. Per below config expected after 120seconds( = [tcp_keepidle] + ( [tcp_keepintvl * tcp_keepcnt] ) instead it keeps resending TCP keepalive packets at varying intervals for varying duration length(like 6mins, 14mins..) before resetting the TCP connections. Also want to mention that we are not using TCPOPS module here. I am trying to achieve consistent duration for TCP reset in kamailio. Could you please point me if I have missed anything here? Setup: Client ---- Kamailio (stateless mode) ---- Backend server TCP Config: tcp_connection_lifetime = 3600 tcp_accept_aliases = no tcp_async = yes tcp_connect_timeout = 10 tcp_crlf_ping = yes tcp_keepalive = yes tcp_keepcnt = 3 tcp_keepidle = 30 tcp_keepintvl = 30 # Total 2 mins - 30+(30*3)=120 sec tcp_linger2 = 30 tcp_rd_buf_size = 65536 tcp_send_timeout = 10 thanks, raj

How reply INVITE request with 200 OK that contains SDP?
by Ali Shirvani 11 Jun '19

11 Jun '19

Hi all, I tried to implement simple announcer by using play_media function in latest rtpengine module. I implemented simple Lua script and I tried to test the implementation with simple SIPp scenario. Here is the Lua function to reply the received INVITE request. ```Lua function ksr_route_announcer() KSR.info("======= Announcer =====\n"); local u = KSR.pv.gete("$rU"); KSR.info("username is: " .. u .. "\n"); if u == "ann" then KSR.info("announcer has been called.\n"); if KSR.textops.has_body_type("application/sdp") then KSR.info("request contains SDP.\n"); KSR.tm.t_newtran(); KSR.rtpengine.rtpengine_manage0(); KSR.tm.t_reply(200, "OK"); KSR.x.exit(); end end end ``` According to kamailio logs rtpengine modified the INVITE SDP, but I want to add SDP to 200 OK response. How should I manage rtpengine to append SDP answer to the 200 OK response? The attached is the SIPp log, as you can see that last 200 OK doesn't contain SDP. Regards, Ali

Daniel, Actually, the HSS is not returning the uri with the +. There are no users int the HSS database with a public ID with a + so the HSS returns the USER_UNKNOWN. Looking at the PCAP, the I-CSCF sends a diameter msg to the HSS asking for the verification the public ID of: Public-Identity: sip:+alice@ims522.irisims.org The diameter msg from HSS is returning : AVP: Experimental-Result-Code(298) l=12 f=-M- val=DIAMETER_ERROR_USER_UNKNOWN (5001) Why do we want the I-CSCF to add a + to all URI's don't start with a +? The I-CSCF is the module that is adding the +, assuming that we should be able to included Kamailio.cfg for respective modules, is there a directive or variable that I need to set?

Relay NAP Probing
by Duarte Rocha 11 Jun '19

11 Jun '19

Greetings, I have a Kamailio as Sip Proxy between my clients and my Media gateway. I have NAPs (One per client) for clients and NAPs for the MediaGateway (One for each client). The MediaGateway probes Kamailio in order to see if it's alive and Kamailio probes clients. However, i would like for the MediaGateway to be aware of the client status. I thought of a few solutions : - When Kamailio probes a client and it fails, both NAPs (Client Side and MG side) could be set as inactive. - Automatically relay the MG probe to the client - Some scripting that reads the result of dispatcher.list and if it finds an inactive NAP, set the MG NAP as inactive too. Is there a better/simpler way to do this? I'd rather have everything on Kamailio configuration files instead of doing exatra scripting. Any opinions ? How can i achieve this? Best Regards, Duarte Rocha

Hello, I hope you can help, We are trying to connect our SIP trunk to our new PBX system, however our SIP trunk provider requires a static IP to add to the endpoint. Our new PBX provider uses a range of IPs that are connected to a domain and the IPs change all the time. Is there a way of using Kamailio that we could get our Sip Trunk provider and PBX system to work together? Regards

Question about setbflag and isbflagset usage
by Володимир Іванець 07 Jun '19

07 Jun '19

Hello everyone! I'm not sure if I correctly understood the description of functions *isbflagset* and *isbflagset* so once again I'm asking for help :) Here is what I do: 1. Asterisk sends INVITE to Kamailio. Kamailio performs lookup of available contacts and then few checks in branch_route. I'm adding *setbflag("17", $T_branch_idx);* there. 2. Later in route[NATMANAGE] I added *if (isbflagset("17", $T_branch_idx)) {* and additional logic. *isbflagset* results in *true* (for same INVITE). 3. Finally one of UACs responds with 200 OK. Asterisk generates ACK packet that gets in route[NATMANAGE]. *isbflagset* results in *false*. So my question is: shouldn't *isbflagset* be *true* for ACK too since it's the same branch or I interpreted these fenctions incorrectly? Thanks a lot!

Re: [SR-Users] [EXT] Re: ICSCF mysql error
by Bao, Yin 07 Jun '19

Yes I think you are right it’s the mismatch of uri. However we don’t know which configuration resulted that mismatch. Here are a bit more details: ICSCF prepared this query: select * from impu where identity=? And it provided sip:+alice@irisims.org as the parameter for the query However the HSS impu table as well as the SIP INVITE only contains: sip:alice@irisims.org I am suspecting the additional + may be causing this mismatch. But where is the + coming from and why ICSCF add this in front of original INVITE line uri? Thanks!

reading php script result with exec_avp
by Gertjan Wolzak 07 Jun '19

07 Jun '19

Hello Kamailions, I have the following challenge. I want to create a time dependent callerid, based on the time of a outgoing call a callerid will be set. I have a php script, that provides me an id number which relates to an cli. When I run that php script from the console, the id is shown in the console. When I run the script within the kamailio configuration, exec_avp("../script.php", "$avp(s:cliId)"); ,no output commande is saved in the avp variable. I think I am not presenting the result of the php script correctly. I have tried with an echo $variable; and with and fwrite(STDOUT, $variable); but no luck. I'm not a PHP coder so I am not surprised of the missing luck, but maybe somebody has a golden tip for me? Rgds, Gertjan

The scenario is simple, using dispatcher with hard coded IP URIs [sip:10.10.10.10:5060] and also a DNS name URI [sip:sip.domain.com]. There are 2 SRV servers. The DNS SRV records are setup and resolving OK, during startup, kamailio list the DNS name in the dispatcher list. During a call scenario, when the dispatcher selects the DNS name URI for the next destination, the TM module takes over, resolves the _sip._udp.sip.domain.com for both SRV records OK and sends the call to the first SRV server in the list. But if I take the first SRV server offline, make another call, the TM module does not route to the second SRV server until the DNS record timeout is reached, in my lab was set for 300 seconds. I decreased the DNS SRV record TTL down to 5 seconds with same results above, but 5 seconds lapse when TM routes call to next SRV server. I think this is working as expected but not sure if this is by design so my question is, should the TM module route to another SRV server in the list in the event of a no response timeout or send the transaction back to the dispatcher to select another target? Should I play around with the TM Module parameter "max_noninv_lifetime" to get quicker results or it is better to have DNS SRV record TTL set really low? Thanks.

Hello, check you kamailio configuration file, the 604 reply is likely to be generated there -- although I haven't written any of the ims modules, typically the reply generated by kamailio are from configuration file, not hardcoded in the source.

Use dmq module with private and public IP addresses
by Markus Bönke 05 Jun '19

05 Jun '19

Hello NG, I have a question regarding the dmq / dmq_userloc module. In my test setup have 2 Kamailio servers in 2 different data centers. The data centers are interconnected by a crosslink. Each Kamailio server has configured an internal (private) and an external (public) IP address. The internal IPs are routed to use the crosslink. The external IPs are routed through the public internet by different ISPs. The requirement is that the replication should primarily be routed via the crosslink, only if the crosslink is down it should be routed via public internet. As I understand the „server_address“ parameter can have only one IP address. If I configure the public IPs on both sides and one ISP connection gets disconnected, packets will NOT be routed automatically via the crosslink. And the other way around, if I configure the private IPs on both sides and the crosslink gets disconnected, packets will NOT be routed automatically via public internet. Is there any way to setup and use dmq for such a scenario ? Thanks and regards Markus

RTPEngine and dialog moving.
by Igor Olhovskiy 04 Jun '19

04 Jun '19

Hi! Wanted to clarify some info about rtpengine working within HA-environment. Idea is we have multiple rtpengines under same setid. So, when I'm calling rtpengine_offer() I really don't care which is selected. But than might happen situation, where this call(dialog) is moved to other Kamailio instance (via dlg_db_load_callid()) and from there called rtpengine_delete(). So, my question is, how I can be sure, that delete request will go to same rtpengine instance that was selected in rtpengine_offer() on different server. And where this info is stored, within dialog or within TM module (which is not replicated in any way) Regards, Igor

Info: app_lua_sr module - old Lua sr library
by Daniel-Constantin Mierla 04 Jun '19

04 Jun '19

Hello, several days ago I split the app_lua module, relocating the code related to old Lua sr library to app_lua_sr module, keeping in this way app_lua smaller and focused to the KEMI code. Over the time, app_lua_sr should be deprecated and removed, as we are sure the functions in Lua sr have an equivalent in Lua KSR. Therefore, if you are using in Lua scripts functions from 'sr' library, consider migrating to KSR as soon as possible. The intermediary solution for a quick upgrade to master version (to be release as v5.3.x) is to load app_lua_sr and update some modparams, like: loadmodule "app_lua.so" loadmodule "app_lua_sr.so" modparam("app_lua_sr", "register", "sl") If you find a function from Lua sr not available in Lua KSR, then report it via mailing lists or bug tracker. An article about this topic was published at: * https://www.kamailio.org/w/2019/05/new-module-app_lua_sr/ Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda

Removal of Dispatcher
by Colin, Andrew 04 Jun '19

04 Jun '19

I am using the API to remove dispatchers with a simple curl command, is there a way i can make kamailio check that there are sufficient dispatchers available before removing them when the command is run? Example: i am removing asterisk1 out of kamailio dispatcher list, but kamailio needs to ensure that there is atleast 2 or 3 other asterisk servers active in the list before it allows it to be removed. any ideas how i can achieve this?

AAR change subscription ID
by eyas barhouk 03 Jun '19

03 Jun '19

dear community, when i'm trying to deploy kamailio IMS with PCRF i get ims-qos AAR error due to Subscription id. in ims_qos module i found that i can change the subscription_id type and value as following: * subscription_id to hard code subscription ID for AAR. Used for some broken PCRFs. Leave blank to use default * subscription_id_type to hard code subscription ID type for AAR. Only applicable if subscription_id is set. Set to -1 to use default. This is as per RFC 4006: END_USER_E164 0, END_USER_IMSI 1, END_USER_SIP_URI 2, END_USER_NAI 3, END_USER_PRIVATE 4 but when i changed it there was no change on AAR Subscription-id AVP. any advise about how to set or change the subscription id dears ??

Releasing a new version for Siremis
by Daniel-Constantin Mierla 03 Jun '19

03 Jun '19

Hello, after quite a bit of time, we are considering to release a new version for Siremis - the web management interface for Kamailio. A lot of effort has been pushed to address the issues with PHPv7.x, which deprecated a lot of PHPv5.x API as well as made more strict rules in regards to classes and inheritances. At this stage it should be in good stage, but it would help if others can give it a ride to Siremis master branch: * https://github.com/asipto/siremis Installation guidelines: * https://kb.asipto.com/siremis:install51x:main Testing with both PHP v5 and v7 is appreciated in order to be sure things were not broken for old systems. Any issue found should be reported on github project issue tracker. If all goes fine, in soon we will make the release.

usrloc extra attributes and db_mode=0
by Patrick Wakano 29 May '19

29 May '19

Hello list, Hope you all doing well! I am trying to use the extra attributes (xavp_contact) of the usrloc module to save some additional info about the user. I am setting the value before the save() and doing a call to registered() (not lookup()) before trying to access these extra attributes. This works fine with db_mode=3 but does not work in case of db_mode=0. Does anyone knows if it should also work with mode 0? I was expecting it to work but a call to kamcmd ul.dump show nothing related..... I don't want to use the DB for the location purposes because I prefer to have multiple servers using the dmq_usrloc (that works like a charm!) and it conflicts with DB persistence of the location table (when the DMQ replication happens, all servers (sharing the same DB) try to save the same user info in the location table) Thank you, Kind regards, Patrick Wakano

Statistics help
by Duarte Rocha 29 May '19

29 May '19

Greetings, I'm doing some monitoring of my Kamailio in order to quickly identify system failures and overloads. In order to do that i have scripts that read the output of "kamcmd sl.stats" and identify the rising of "500_replies", "5xx_replies" and "6xx_replies". However, i have rate limiting on my Kamailio, which generates "503" replies when limit is reached, which generates an unnecessary alarm. Is there a way to get more specific stats about the repleis generated by Kamailio? If that isn't possible, will i be safe only monitoring "500" and "6xx" replies? In my experience, when the server has reached a processing or memory limit, the reply is always 500, but i'm not really sure about this. Thank you for your help. Best Regards, Duarte Rocha

Push proxy and load balancer for asterisk?
by Gerrit Jacobsen 29 May '19

29 May '19

Good morning, I want to realise a push notification proxy to signal incoming calls from asterisk to softphones. Is Kamailio the preferred solution for this? I looked also at Flexisip and Asterisk scripts and was told by a seasoned professional that Kamailio is the preferable solution as its scalable. True? I would be glad if someone could share his experiences. Also can one Kamailio instance be used as an asterisk load balancer and also push notification proxy ? I have been a heavy openser user a long time ago. I used first openser as my core routing engine but then switched to yate. Please excuse my rather broad questions. From my experience with Openser the devil is in the detail. So any hints on where this setup may cause problems would be great. Thanks a lot for your input. Gerry

RFC: split out old sr api from app_lua
by Daniel-Constantin Mierla 29 May '19

29 May '19

Hello, I am considering to split the app_lua module in order to move the older style API available under Lua 'sr' module in a dedicated module (like app_lua_sr). Later this module can be obsoleted and removed, once we know that everything there is covered by KEMI KSR Lua module. In this way, we make it more clear that KSR is the preferred API to use as well have the app_lua smaller, for those using only KSR and not needing 'sr' API. Therefore I am starting the discussion to see if anyone has something against or other suggestions. I cc-ed sr-dev to make developers aware, but I think the best place for discussion is sr-users, being related to how Kamailio is used, therefore reply only to sr-users.

RTPEngine / Transcoding question
by Carsten Bock 29 May '19

29 May '19

Hi, I want to implement selective transcoding, e.g. avoiding Transcoding between a HD codec (G722) and a non HD Codec (G711). In case the caller does offer HD codecs, this is fine, e.g. if(sdp_with_codecs_by_name("G722,OPUS")) { rtpengine_offer("codec-transcode=OPUS codec-transcode=G722 codec-transcode=PCMA"); } else { rtpengine_manage("codec-transcode=PCMA"); } Now I have the issue, if the callee only sends me G711, I don't want to offer G722 or Opus to the caller. However, rtpengine_answer() does not seem to accept "codec-strip=G722 codec-strip=OPUS", e.g.: onreply_route() { if(!sdp_with_codecs_by_name("G722,OPUS")) { rtpengine_ manage("codec-strip=OPUS codec-strip=G722"); } } As a result, the SDP always contains the transcoding options, e.g. G722 and OPUS. I always end up in transcoding G722 to G711, which is meaningless in that case. Any ideas on how to solve that? (above examples very simplified) Thanks, Carsten -- Carsten Bock I Managing Director ng-voice GmbH Millerntorplatz 1 I 20359 Hamburg I Germany www.ng-voice.com Mobile +49 (0)179-20 21 244 I Direct +49 (0)40-52 47 593-40 I Fax +49 (0)40-52 47 593-99 Sitz der Gesellschaft: Hamburg Registergericht: Amtsgericht Hamburg, HRB 120189 Geschäftsführer: Carsten Bock, Dr. David Bachmann Ust-ID: DE279344284 Hier finden Sie unsere handelsrechtlichen Pflichtangaben: http://www.ng-voice.com/imprint/

RTPEngine: rtpengine_manage(), Subsequent requests, Transcoding
by Carsten Bock 29 May '19

29 May '19

Hi, quick question: If understood it correctly in the past (and it worked for me quite well this way), I can simply call rtpengine_manage() for subsequent requests without adding any additional information (e.g. used interfaces, RTP/SRTP translation or anything like that), as this information is stored in the internal hash table of the RTPEngine module during call setup and initial offer/answer. However, this does not seem to apply to the transcoding options. When I just call "rtpengine_manage()" for a Re-INVITE of a transcoded call (in my case AMR-WB to G722), the transcoding options are no longer applied. The forwarded offer does not get the transcoded codecs added (e.g. in my case G722 is not added to the list of AMR/AMR-WB from the phone). Did I misunderstand something or is it a bug? My RTPEngine is still on 7.2, but I will double check with more recent versions today or tomorrow. However, I also found no commit messages relating to this.

Hi Everyone When P-CSCF receives INVITE from client it sends INVITE to S-CSCF then S-CSCF without any look up(checking the user is registered or not)sends INVITE to I-CSCF then I-CSCF sends LIR and receives LIA and sends INVITE to same S-CSCF (in case of one S-CSCF exists).My Question is here why without any look up S-CSCF sends INVITE to I-CSCF??this procedure affects system performance and increases call set up time

remove_hf() leaves junk in the headers?
by Oded Arbel 27 May '19

27 May '19

I'm trying to rewrite the `From` header in an invite going out to an external system (*), by calling remove_hf("From"); followed by append_hf("From: <some value>\r\n"); but the result is an invalid SIP message, because apparently after `remove_hf()` finishes, it leaves the content of $fU in place of the `From` header - just the raw text, without a header name or even a "\r\n" - and that eats the next header line and breaks the INVITE. Here is how the INVITE originally looks (without either `remove_hf()` or `append_hf()`): ---8<--- INVITE sip:972522353283@10.20.30.40:5060 SIP/2.0 Record-Route: <sip:10.90.80.70;lr;did=649.f0b> Via: SIP/2.0/UDP 10.90.80.70:5060;branch=z9hG4bK6188.ff5c4fd855bd2970fdf32d4807b114c2.0 Via: SIP/2.0/UDP 10.90.80.71:5066;received=10.90.80.71;branch=z9hG4bK581897a4;rport=5066 Max-Forwards: 69 From: <sip:972515340014@example.com:5066>;tag=as0bcee217 To: <sip:972522353283@10.20.30.40:5060> Contact: <sip:972515340014@10.90.80.71:5066> Call-ID: 722299dc15aad53d28172d433e8665f4@10.90.80.71:5066 CSeq: 102 INVITE User-Agent: Asterisk PBX 14.7.2 Date: Sun, 26 May 2019 14:42:52 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces X-CID: ad199638-4df3-4aef-81f1-1b50581032a7 Content-Type: application/sdp Content-Length: 280 v=0 o=root 817636675 817636675 IN IP4 10.50.60.70 s=Asterisk PBX 14.7.2 c=IN IP4 10.50.60.70 t=0 0 m=audio 39064 RTP/AVP 8 0 18 9 a=maxptime:60 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:18 G729/8000 a=rtpmap:9 G722/8000 a=sendrecv a=rtcp:39065 a=ptime:20 ---8<--- and here is another call with the same setup, with just `remove_hf("From");` being invoked (without calling `append_hf()` - this is just for reproduction): ---8<--- INVITE sip:972522353283@10.20.30.40:5060 SIP/2.0 Record-Route: <sip:10.90.80.70;lr;did=f45.91b1> Via: SIP/2.0/UDP 10.90.80.70:5060;branch=z9hG4bK024d.2690ebf7a809edca2208e6b2561ccf9e.0 Via: SIP/2.0/UDP 10.90.80.71:5066;received=10.90.80.71;branch=z9hG4bK79ae3073;rport=5066 Max-Forwards: 69 972515340014To: <sip:972522353283@10.20.30.40:5060> Contact: <sip:972515340014@10.90.80.71:5066> Call-ID: 7b20ba5a549f6f886c22985146765736@10.90.80.71:5066 CSeq: 102 INVITE User-Agent: Asterisk PBX 14.7.2 Date: Sun, 26 May 2019 14:44:20 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces X-CID: ffbb4ac1-3a0f-4dd6-9ce9-7ad24361081a Content-Type: application/sdp Content-Length: 280 v=0 o=root 509740923 509740923 IN IP4 10.50.60.70 s=Asterisk PBX 14.7.2 c=IN IP4 10.50.60.70 t=0 0 m=audio 39102 RTP/AVP 8 0 18 9 a=maxptime:60 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:18 G729/8000 a=rtpmap:9 G722/8000 a=sendrecv a=rtcp:39103 a=ptime:20 ---8<--- As you can see, the `From` header is indeed gone, but it left the $fU just before the `To` header.

PRE-PAY update timer
by Steve Bucklin 25 May '19

25 May '19

Hello all (again), I am looking at a 'good' method to start a call with "chunks" of time allocated. I wish the initial call to check a credit, and if credit is good, allow a small amount of time (say 30 seconds). I have enabled DIALOG and have looked at CNXCC, but am confused! When the initial 30 seconds runs out, I want to authorise another 30 seconds, etc, etc, etc. I have started to play and set a dialog timer that expires to a route, and then can 'return' allowing the call to continue - BUT was not able to reset the dialog timer to trip again after another 30 seconds. I tried to 'set_max_time' on cnxcc, but this did not seem to trip the event route upon timeout? Does anyone have a pointer to any examples? I also am unsure of how to update the timer and keep a call in play! Steve

Hi , We have successfully installed the kamailio IMS server on centOS 7 using the following link (http://www.kamailio.org/wiki/tutorials/ims/installation-howto) with appropriate changes for command in CentOS 7. We are currently trying to integrate the PCSCF module with LTE Core network , but I don't have any idea how to do this. Neither I am able to find any tutorials which I can use to understand how kamailio works. Can anyone share any reference document to help me understand the kamailio working in my use case.

Kamailio CDRs for calls interrupted without BYE
by Ildar Mukhametzhanov 23 May '19

23 May '19

Hello! I am using dialog+acc modules to write CDRs in kamailio. Everything works great except one test. During active call I switched off both UACs preventing them to send BYE. Rtpengine reported about call interruption, but kamailio thinks that this call is in-progress for a long time. What is the right way to make kamailio know about calls interrupted without BYE. Thanks. -- Sincerely, *Ildar Mukhametzhanov* Head of software development VoiceON Telecom Services GmbH im(a)voice-on.net <mailto:im@voice-on.net> t. +49 30 398 20 500-77

Re: [SR-Users] Modern SIP Trunking, Route on To: or INVITE Headers?

Benoit, Alex, I appreciate the feedback, confirming my assumptions. Good news is the Vendor finally responded positively and agreed to add in configuration option to route on INVITE R-URI in next SDK release, expected later this year. In the meantime I added 'uac_replace_to' function to my proxy to re-write To: header with R-URI, so far so good. Thanks.

Hello, I am considering to release Kamailo v5.2.3 out of latest git branch 5.2 next week, likely on Wednesday, May 22. As usual, if you are aware of issues not reported to the github bug tracker, fill a report there as soon as possible to give a chance to be analyzed and fixed. Also, if there was a fix for an issue that you were reporting, check to see if it was backported to be sure it is not forgotten.

Modern SIP Trunking, Route on To: or INVITE Headers?
by JR Richardson 21 May '19

21 May '19

Hey Folks, I could use some feedback to see if my mind is right on this topic.I'm in a discussion with a software Vendor (respectfully unnamed) with terminal software routing on To: header info. It's my contention any modern SIP software should use INVITE header to retrieve DID info and route from there. My reasoning is due to the To: header should contain the original intended DID, Extension, Name, AoR or whatever else the original SIP transaction wanted to contact, but being in a multi-carrier, multi-hop, call forwarding environment, the INVITE header contains the hop-to-hop true intention of where the call should route at any given transaction. So in the case of terminal software the To: header could likely be irrelevant where as the INVITE header is accurate. My most recent response from the Vendor suggest I put a SIP Proxy in front of the terminal software and transform the To: header to whatever I need for this application. Although I can do this, I'm concerned with breaking RFC for CANCEL and BYE transaction sent back from the terminal software that may not be recognized by upstream origination carriers. Plus modifying To: header is widely frowned upon by most folks. Thanks. JR -- JR Richardson Engineering for the Masses Chasing the Azeotrope
