exit stop procesing or not after a conditional? based on "exit" core docs seems does not explain behaviour
by PICCORO McKAY Lenz 26 Aug '19

26 Aug '19

in my kamailio-asterisk integration i have a exit after the authentication logic, BUT; there's another conditional after the "exit" sentence, so my ask, if there's a exit in that piece of code .. that next conditional will not be executed? Docs seems said "stop execution of script" so all the rest of the logic in file will not be routed? The documentation seems does not explain in good behavior what happened or the kamailio-asterisk wiki page does not have good explanations for that! it's that an error? https://www.kamailio.org/wiki/cookbooks/4.3.x/core#exit - - ``` if (from_uri==myself) {#!ifdef WITH_ASTERISK if (!proxy_authorize("$fd", "sipusers")) {#!else if (!proxy_authorize("$fd", "subscriber")) {#!endif proxy_challenge("$fd", "0"); exit; } if (is_method("PUBLISH")) { if ($au!=$tU) { sl_send_reply("403","Forbidden auth ID"); exit; } } else { if ($au!=$fU) { sl_send_reply("403","Forbidden auth ID"); exit; } } consume_credentials(); # caller authenticated } else { # caller is not local subscriber, then check if it calls # a local destination, otherwise deny, not an open relay here if (!uri==myself) { sl_send_reply("403","Not relaying"); exit; } } } #!endif return; } ``` 8:52 am Lenz McKAY Gerardo (PICCORO) http://qgqlochekone.blogspot.com

reply cannot be forwarded - no 2nd via
by Ryan McEvoy 25 Aug '19

25 Aug '19

Hello, I have been having an issue using kamailio to load balance to a SIP/MRCP server. I believe that the issue actually lies with the reply being sent from the final recipient, but I wanted to be sure that I understood the problem and to see if there were any possible solutions within Kamailio. I am using the dispatcher module to dispatch SIP INVITES to media resources, in this case I am just using a single host in a single dispatcher group. The configuration that I have has worked just fine for other SIP/MRCP servers, which is why I think the issue is with this target in particular. The INVITE is routed correctly and contains the headers that it should. The invite comes originally from a Freeswitch, arrives at Kamailio, who should then dispatch to a host in the group. x.x.x.x:4901 is Kamailio x.x.x.x:8090 is Freeswitch y.y.y.y:8000 is the final target This is the invite, as received by the final target after dispatched via Kamailio INVITE sip: x.x.x.x:4901 SIP/2.0 Record-Route: <sip: x.x.x.x:4901;transport=tcp;lr> Via: SIP/2.0/TCP x.x.x.x:4901;branch=z9hG4bK3a9a.7f9a4b588cd75108cfea9a2bd9ffa829.0;i=3 Via: SIP/2.0/TCP x.x.x.x:8090;branch=z9hG4bKStXp06Sv7jU7S Max-Forwards: 69 From: <sip: x.x.x.x:8090>;tag=4gHgNcNUDjvFQ To: <sip: x.x.x.x:4901> Call-ID: 6f2a0e9c-3f9e-1238-2aa9-005056854777 CSeq: 8692231 INVITE User-Agent: tts Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, PRACK, MESSAGE, SUBSCRIBE, NOTIFY, REFER, UPDATE Supported: timer, 100rel Content-Type: application/sdp Content-Disposition: session Content-Length: 281 v=0 o=IPSoft 3367790083977298880 2789991278648035021 IN IP4 x.x.x.x s=- c=IN IP4 x.x.x.x t=0 0 m=application 9 TCP/MRCPv2 1 a=setup:active a=connection:existing a=resource:speechsynth a=cmid:1 m=audio 32038 RTP/AVP 0 a=rtpmap:0 PCMU/8000 a=recvonly a=mid:1 The reply that the server sends back appears to be missing a second Via header, which is preventing Kamailio for routing it correctly (based on the error message from core/forward.c) This is the reply sent by the target destination SIP/2.0 200 OK Via: SIP/2.0/TCP x.x.x.x:8090;branch=z9hG4bKStXp06Sv7jU7S To: <sip: x.x.x.x:4901>;tag=ndszib3k From: <sip: x.x.x.x:8090>;tag=4gHgNcNUDjvFQ Call-ID: 6f2a0e9c-3f9e-1238-2aa9-005056854777 CSeq: 8692231 INVITE Contact: "Voiceware MRCP Server" <sip:vwmrcp@ y.y.y.y:8000;transport=tcp> Content-Type: application/sdp Content-Length: 324 v=0 o=- 1566492047 1566492047 IN IP4 y.y.y.y s=Voiceware MRCP Server 2.15.0.7.

If so, is there anything else that can be done in Kamailio to handle this, or is this mrcp server simply not complying properly with SIP? There’s no funky natting between these hosts or anything like that. Thanks in advance!

set_rtpengine_set question

24 Aug '19

When set_rtpengine_set() is called with two parameters before rtpengine_offer(), e.g. set_rtpengine_set("1", "2"); rtpengine_offer(); it was not clear to me from rtpengine README, if the sets need to reversed when set_rtpengine_set() is called before rtpengine_answer(), i.e., set_rtpengine_set("2", "1"); rtpengine_answer(); or can the order of the sets be the same as it was in case of rtpengine_offer()? -- Juha

Dealing with optional SRTP
by Mark Boyce 24 Aug '19

24 Aug '19

Hi all (Using Kamailio + RTPEngine, both current stable versions) Just wondering what current best practice is for dealing with “optional SRTP” such as those generated by Yealink devices. (I know this breaks the RFC but lots of things seem to use this method.) Where the device SDP message looks like; m=audio 50004 RTP/AVP 8 97 101 a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:uhJOWOXPuzMeBmrbx2wAKohuveAvZeMEJTzfE7GT a=crypto:2 AES_CM_128_HMAC_SHA1_32 inline:yF+EhR3RtxSDCGtLCnEAl3Zrdut4b8cfFQP+hFqf An unencrypted RTP/AVP media line but with crypto lines showing that the device will support SRTP encryption but it is not mandatory. The system of offer SRTP and try and catch on not supported/acceptable here fail feels a little clumsy and relies on how gracefully the device sends “not acceptable here”. I’m wondering if I just short cut it and say that if a device offers a acceptable crypto line then Kamailio sends back a SAVP response. Naturally this question is then closely followed by how to do optional SRTP invites originating from Kamailio without just directly manipulating lines? Feels like there should be an RTPEngine setting for Optional? RTP/AVP+SAVP ? Thoughts? Mark

Kamailio as an Outbound Proxy - Strange Sip Flow
by Diogo Hartmann 23 Aug '19

23 Aug '19

Hello Kamailio experts, We have a Kamailio as outbound proxy in front of Asterisks PjSIP. There is a strange behavior after 200 OK: - ACK comes from Asterisk Public IP instead of coming from the internal IP address. - BYE can not be processed (404 not here) SNGREP print attached. Has anyone ever experienced this? I can provide more information if needed, just let me know what info. Thanks! Diogo Hartmann

Cant finish call
by przeqpiciel 23 Aug '19

23 Aug '19

Hi all, I am totally new with Kamailio but i have needs to build small cluster of Asterisk. Right now I could succesfully register to asterisk via kamailio and even make a call to hear tt-weasels but Asterisk cant close call My infrastructure diagram is here http://www.asciidraw.com/#Draw6816041626716434245/903175935 This is what probably I need is to know how to tell to Asterisk that send BYE to private IP of Kamailio instead public IP of Kamailio, am I right ?

TCP: Strange Device Behaviour
by Carsten Bock 23 Aug '19

23 Aug '19

Hi, I have a device here, which does some sort of strange things: I have SIP Message, e.g. with a length of 1100 Bytes and the devices adds "0" to the end to meet the MTU of the network (for a single TCP frame), some sort of TCP padding. The following TCP Frame contains only the next message. Looking at the trace in Wireshark, sngrep or similar, all of them try to re-assemble the next message in the TCP stream, but however don't decode them as SIP due to to first couple of zero's in the message. Looking at Kamailio, it seems not to have any issues with this and decodes/parses the message properly (they show up on Homer properly); however it also forwards the message INCLUDING the first couple of zero's even on UDP. To make it complitely irritating, the phone itself would ignore such packets, if we would forward them to the phone with starting zeros. Has anyone seen anything like this and is it standards-compliant? Any proper and easy way to get rid of the starting "zero's" from a message before forwarding these messages? I could always "hack" something into src/core/tcp_read.c, but I wonder if there is already a proper way? Any ideas anyone?

About STIR/SHAKEN - Caller Identity
by Daniel-Constantin Mierla 23 Aug '19

23 Aug '19

Hello, at couple of events I participated during the past few months, I was asked about support of STIR/SHAKEN (caller identity authentication/verification), which is a hot topic these days at least in USA, aiming to combat "fraudulent" robo-calling. Therefore I thought of share some details with everyone in the community about the state in Kamailio, writing to both devs and users, the information being relevant for everyone. We already have the (related) module named auth_identity, available since 2008 (iirc): - https://www.kamailio.org/docs/modules/stable/modules/auth_identity.html But it implements the previous iteration of the specs for caller identity, respectively RFC 4474: - https://tools.ietf.org/html/rfc4474 However, that RFC is obsoleted by 8224 (the latest core specs for STIR/SHAKEN): - https://tools.ietf.org/html/rfc8224 Then, there are also RFCs 8225 and 8226 to add to the core specs. Should anyone be interested to implement STIR/SHAKEN specs in a modules, I would suggest to start from auth_identity -- might not be much work to update it to become conform with latest specs (a new module can be created, of course, even when starting from auth_identity). However, these specs are about signing the SIP request (the INVITE) with special PKI certificate. It can be done easily with embedded scripts such as Lua or Python (inline execution in native kamailio.cfg or using kemi scripts). At Kamailio World 2019, one of the participants I discussed with told me they already implemented using Lua. That's it for a starting point, if anyone wants to discuss more, just reply to sr-users and add your comments or ask the questions. If someone wants to go ahead and work on a C module, announce yourself to avoid duplicate work of others, and use sr-dev if you need assistance on module development.

basic Kamailio frontend to Asterisk
by Travis Ryan 22 Aug '19

22 Aug '19

All, I would like to use Kamailio as a frontend/proxy for an asterisk machine/cluster. I'm very well versed in Asterisk, but VERY noob to Kamailio. I've watched so many Kamailio presentations and feel like I've scoured the web for any article that could help me. There is alot out there, but I'm not finding my exact situation. I believe I understand the dispatcher stuff that I'll need down the road, but I'm having issues understanding the setup of my SIP trunk and Kamailio. I used UAC to setup the trunk connection in Kamailio and it sort of worked. I'm not sure what I do for Asterisk. I'd suspect that in this situation Kamailio would handle the registration and trunk connection for me. What role is Kamailio to my Asterisk? Just an Outbound proxy? Do I need to still register the trunk from each Asterisk box "thru" the Kamailio proxy, etc? Also, I'm merely accepting outside calls and then validating the caller and bridging them back out to the PSTN, so I don't have any local SIP clients, etc., so no need to register the sip devices, etc. Thanks! Travis

Slowly increasing PKG memory usage
by Andrew White 20 Aug '19

20 Aug '19

Hi all, I had a Kamailio crash the other day, and some debugging showed I ran out of PKG memory. Since then I’ve run a simple bash script to compile the amount of memory used by all child processes, effective /usr/local/sbin/kamcmd pkg.stats | grep real_used summed together. I’ve graphed out the data, and there’s a clear growth of PKG memory going on, mostly increasing during our busier daytime hours. https://i.imgur.com/UTzx2k1.png Based on this, I suspect either a module loaded or something within my app_ruby conf is leaking memory. I’ve been reading through https://www.kamailio.org/wiki/tutorials/troubleshooting/memory <https://www.kamailio.org/wiki/tutorials/troubleshooting/memory>, but I’m a bit nervous, as I’m not really a C/deep memory type of guy. I can see a GDB script I can attach to Kamailio, but is that going to use significant resources to run or impact the running process? Is there a newer/better/alternative way to do this, and to help me break this down? Thanks! Andrew

Replacing Caller ID
by Pete Kay 18 Aug '19

18 Aug '19

Hi Could anyone tell me if there is a module for replacing the caller ID in the SIP messages? I need to replace the caller ID when the call comes in and leaves Kamailio. When the egress sends back any response, I need to revert the caller ID back to its normal form. I have a long list of numbers to be used as caller-ID, and I need to keep modifying them without having to restart Kamailio. Do I need to write my own modules for maintaining the list of numbers to be used as caller-id? I am running at 2000 CPS, so I think I need to implement some sort of hash table in order for the caller id to be retrieved in round roubin fashion very quickly. Is there any modules for this purpose or I need to write a cusom one? Pete

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

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*

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
