Problem with replicating dialogs using DMQ
by Jan Hazenberg 01 Oct '18

01 Oct '18

Hello, I'm trying to replicate active dialogs using the DMQ module. I see the dialogs on the other nodes but it generates a error message in the logs on all the nodes: Sep 27 10:17:31 sip04 /usr/sbin/kamailio[27367]: CRITICAL: dialog [dlg_timer.c:130]: insert_dlg_timer(): Trying to insert a bogus dlg tl=0x7efdca1bebf8 tl->next=0x7efdca14cb80 tl->prev=0x7efdca14cb80 Sep 27 10:17:31 sip04 /usr/sbin/kamailio[27367]: CRITICAL: dialog [dlg_dmq.c:309]: dlg_dmq_handle_msg(): Unable to insert dlg timer 0x7efdca1beb98 [2643:3725] Even with the timeout_avp option disabled i still see the error messages. I tested this on kamailio 5.0.3 and 5.1.3 with the same results. With debug enabled i see the correct data is replicated to the other nodes: dlg_dmq_replicate_action(): sending serialized data {"action":2,"h_entry":1328,"h_id":409,"state":4,"start_ts":1538036606,"lifetime":7200,"tag1":"1635359980","tag2":"as2d80799c","cseq1":"21","cseq2":"0","route_set1":"","route_set2":"","contact1":"sip:sipuser@10.10.10.10:1057 ;alias=10.10.10.10~1055~1","contact2":"sip:+31101234567@10.10.10.10:5060"} "lifetime":7200 is in the serialized data, and when i check on the other node with "kamcmd dlg.list" i see that the lifetime data is not updated. Thanks, Jan

registrar lookup with different URI
by Maarten Ureel 30 Sep '18

30 Sep '18

Hello I want the registar module to lookup a user with a different 'name' as the RURI. We have the extension & domain in variables, but the RURI is ext@ip-of-server, e.g. 200(a)1.1.1.1<mailto:200@1.1.1.1>, while we want to perform the lookup for 200(a)somedomain.tld<mailto:200@somedomain.tld>. We have somedomain.tld in a header, so we have it in a variable. However, if we perform the lookup like this (using Python module): lookup_result = KSR.registrar.lookup('location') We get a negative result, and the debug logs show that it tries to locate 200(a)1.1.1.1<mailto:200@1.1.1.1> - which makes sense. So according to docs you can specify an URI, however when I do this: lookup_result = KSR.registrar.lookup('location' '200(a)somedomain.tld') lookup_result is "False" and the function is not executed, according to docs because it cannot obtain the parameters for this function. How can we force the registrar module to lookup a different user?

Dialog timout reset when receiving a re-INVITE
by jenus＠cyberchaos.nl 30 Sep '18

30 Sep '18

Hello, I have a issue with setting the dialog timeout for a call. It works fine until i receive a re-INVITE. The re-INVITE seems to reset the dialog timeout back to the default value configured in the module parameters (7200 in my case). I use "dlg_set_timeout("900");" to set the timeout to 900 seconds. When i receive a re-INVITE i see the following in the debug logs: DEBUG: dialog [dlg_handlers.c:647]: get_dlg_timeout(): invalid AVP value, using default timeout This happens even with the "timeout_avp" module parameter disabled. I'm running kamailio 5.1.3. Thanks, Jan

kamailio rtp connection
by Pieter Muller 28 Sep '18

28 Sep '18

Good day all I hope Im on the right place to ask the question. Im a newbie to kamailio and have a little problem understanding how to set kamailio correctly. Scenario: VoIP Supplier (IP:161.161.252.20{Private Net}) à Connect via routing to Kamailio Server(155.155.16.2 eno2{private Net}),Kamailio Server(187.221.197.252 eno1{public facing})àconnect to PBX(public IP set in dispatcher) à connect to RTP server(Public IP) Now the problem is that if you call in Number(a)161.161.252.20 <mailto:Number@161.161.252.20> is send to kamailio, kamailio then sends it down to dispatcher IP and that PBX responds directly back via rtp server to 161.161.252.20. The 161.161.252.20 IP is private and cannot be reached from the cloud and vice versa . How do I get kamailio to be the middle man between 161.161.252.20 and RTP server(all traffic must go via the kamailio server) Is there specific modules I must load. Im running Kamailio 4.4 Any help would be muchly appreciated. Regards Pieter

Important: new module exports interface
by Daniel-Constantin Mierla 28 Sep '18

28 Sep '18

Hello, as a result of collaborative work at Kamailio Developers Meeting, we succeeded to merge the two existing module exports interface (one for kamailio modules and the other one from ser modules) in a single one. All public modules were updated, but if you have any private module then you have to update as well in order to get it compiled with the latest master. Just look at one of the modules (e.g., sl is a good option) and all the fields in mod exports structure have comments with their meaning. In short: we removed unused fields for statistics, mi commands and extra-processes (from kamailio old interface) and oncancel (from ser old interface), kept the rpc exports from ser interface and pv exports and dlopen flags from kamailio interface. The other fields were common in both interfaces, but be aware that order was also changed. If you have a module implementing the old ser interface, you also need to add the free_fixup_field in functions exports tructure -- you can just set it to 0. With this we have now a single mod exports interface in all modules, the core is also cleaner as we got rid of the various compatibility layers.

Hello, we will do some maintenance work on deb.kamailio.org server these days in order to move to a better infrastructure, so it may not be available for a while -- the DNS needs to be updated as well, this also can affect you if your router/provider does caching. Once we finish with the migration, we will send updates.

Cannot handle Cancel Request properly
by Aqs Younas 28 Sep '18

28 Sep '18

Greetings list, I am getting hard time to make kamailio perfectly handle cancels request. I am using http_async_client and MSILO to handle push notifications. Case 1. When B party record exists in location but it is off-line and I send cancel *instantly* from Party A while kamailio is sending push to wake B Party up. modparam("tm", "failure_reply_mode", 3) modparam("tm", "cancel_b_method", 1) modparam("tm", "fr_timer", 30000) modparam("tm", "fr_inv_timer", 120000) You can see in below picture 407 being generated after some time. [image: default.PNG] What could be the reason of this problem? any pointer is much appreciated. Br, Aqs.

by Andrew Chen 28 Sep '18

Hi Kam community, Facing an urgent issue here and not sure how to troubleshoot it further. So our engineers been getting reports of unknown SIP timeouts and they suspect it's something on the Kamailio side. I've logged every transaction from receiving the message to done relaying it as shown below: Sep 24 18:38:13 sjoprodfnsg01 /usr/local/sbin/kamailio[42608]: INFO: <script>: [1589Fz-ses1-41d9a88aR70125425(a)xxx.xxx.xxx.xxx][4534123][CSeq 7] NG-FuzeMedia-Server/42ae58c/mediahub Relaying [UPDATE] from (xxx.xxx.xxx.xxx ) to ( xxx.xxx.xxx.xxx ) via (tls) Sep 24 18:38:13 sjoprodfnsg01 /usr/local/sbin/kamailio[42608]: INFO: <script>: [1589Fz-ses1-41d9a88aR70125425@ xxx.xxx.xxx.xxx ][4534123][CSeq 7] NG-FuzeMedia-Server/42ae58c/mediahub Done relay [UPDATE] from (xxx.xxx.xxx.xxx ) to ( xxx.xxx.xxx.xxx ) via (tls) When I pulled the 443 SIP trace from my tcpdump session, it shows the application data left the machine at 18:44 as shown here: [image: image.png] Note: This packet is encrypted and can't see the actual SIP message.

subst_hf to rewrite a contact header
by Ben Hood 27 Sep '18

27 Sep '18

Hi, I’m wondering how to use subst_hf() properly. I’m trying to debug a broken flow by manually rewriting the contact header from Contact: <sip:b73c6f29-0101-4802-afcd-efb63f1e6d8f@10.10.10.12:5090;transport=udp> to Contact: <sip:2018092417381900003@81.x.x.x> by using $var(ctct) = "<sip:2018092417381900003@81.x.x.x>"; subst_hf("Contact", “/\<.+\>/$var(ctct)\r\n/", "a”); but the result is Contact: <sip:2018092417381900003@81.x.x.x> sip:b73c6f29-0101-4802-afcd-efb63f1e6d8f@10.10.10.12:5090;transport=udp Testing the regex with an external tool appears to match all of the original header, so I’m wondering why subst_hf doesn’t appear to rewrite the entire header. Is there something I’m doing wrong? TIA, Ben

Kamailio - Asterisk integration
by denislav.tsonev＠musala.com 27 Sep '18

27 Sep '18

Hello guys, I'm following this guide: https://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb And I have the following schema: Phone A -----> Kamailio -----> Asterisk -----> Phone B (10.0.8.249) (10.0.6.123) (10.0.3.144) (10.0.13.23) I think the flow it is like (because when UAC register to Asterisk, the contact points to Kamailio IP): 1. Phone A --> Kamailio --> Asterisk 2. Asterisk --> Kamailio --> Phone B In attachment is the pcap of the call, kamailio config. The problem is that I never receive ACK after 200 OK and call drops after 30 seconds? Kamailio version 5.1 and Asterisk version 15.1 Phones are grandstreams and also tested with microsip soft client and same results... Like "Phone A" never sends ACK back I tried different approaches to change contact header in 200 OK, because is Asterisk IP. Disable NAT handling. Different "nat_uac_test" flags, but still without success :( Also tried with this NAT detection and manage routes (again without any success) - source https://github.com/sipwise/kamailio/blob/master/etc/kamailio.cfg # Caller NAT detection route[NATDETECT] { #!ifdef WITH_NAT force_rport(); if (nat_uac_test("19")) { if (is_method("REGISTER")) { fix_nated_register(); } else { if(is_first_hop()) { set_contact_alias(); } } setflag(FLT_NATS); } #!endif return; } # RTPProxy control and signaling updates for NAT traversal route[NATMANAGE] { #!ifdef WITH_NAT if (is_request()) { if(has_totag()) { if(check_route_param("nat=yes")) { setbflag(FLB_NATB); } } } if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB))) return; if(nat_uac_test("8")) { rtpproxy_manage("co"); } else { rtpproxy_manage("cor"); } if (is_request()) { if (!has_totag()) { if(t_is_branch_route()) { add_rr_param(";nat=yes"); } } } if (is_reply()) { if(isbflagset(FLB_NATB)) { if(is_first_hop()) set_contact_alias(); } } #!endif return; } Thanks in advance Denislav Raychev Tsonev | Integration and Infrastructure Engineer | Musala Soft JSC www.musala.com | t: +359 2 969 58 21 | m: +359 878 270 965 | f: +359 2 969 58 22 World Trade Center, 36 Dragan Tsankov blvd., Sofia 1057, Bulgaria

create domain "on the fly" in registrar modukle
by Maarten Ureel 27 Sep '18

27 Sep '18

I'm building a setup with FreeSWITCH and Kamailio 5.2 but I'm having troubles in handling the registrations for multiple domains. So far I have in my config these related settings: # Disable database completely modparam("usrloc", "db_mode", 0) # Take domain into account when saving modparam("usrloc", "use_domain", 1) # Preload location table modparam("usrloc", "preload", "location") I'm using the app_python module; when performing the registrar save like this: KSR.registrar.save(KSR.pv.get('$fd'), 1) It fails, the debug shows that it cannot find the domain that the SIP user has here. When I use: KSR.registrar.save('location', 1) The phone registers just fine; however I'm bothered by the fact that the documentation states that you should specify the domain as a parameter. Is it OK if everything is in one 'location' domain? How can I let Kamailio know what domains exist (where does Kamailio get this information from)? We have a unique domain for every customer, like g123.ctx.ourcompany.tld. Kind regards Maarten Ureel

Adding new rtpproxy instance without restarting Kamailio
by Pintu Lohar 27 Sep '18

27 Sep '18

Hi All, I have a very basic question. Is there any way to add new rtpproxy instance without restarting Kamailio? As per my understanding, we can reload the dispatcher table when Kamailio server is running with kamctl dispatcher reload but do we have any such for rtpproxy list also from db when rtpproxy table ? Below is my rtpproxy related config, load from DB , #Once RTPProxy was found unreachable and marked as disabled, #the rtpproxy module will not attempt to establish communication to RTPProxy for rtpproxy_disable_tout seconds. modparam("rtpproxy", "rtpproxy_disable_tout", 120) #only for local host. modparam("rtpproxy", "timeout_socket", "xmlrpc:http://127.0.0.1:8000/RPC2") modparam("rtpproxy", "db_url", "mysql://kamailio:xxxxxxxx@10.xx.xx.xx /kamailio") modparam("rtpproxy", "table_name", "rtpproxy") #enable marker for sdp modification by rtpproxy modparam("rtpproxy", "nortpproxy_str", "a=sdpmangled:yes\r\n") my current instance : ./kamcmd rtpproxy.list { setid: 0 url: udp:xxx.xx.xxx.xxx:7722 index: 2 disabled: 0 weight: 1 recheck: 0 } Db +----+-------+--------------------------+-------+--------+-------------+ | id | setid | url | flags | weight | description | +----+-------+--------------------------+-------+--------+-------------+ | 1 | 0 | udp:XXX.XXX.XXX.XXX:7722 | 0 | 1 | | +----+-------+--------------------------+-------+--------+-------------+ I already explored ./kamcmd rtpproxy.enable command , but it seems that this command is useful for re-enabling or disabling existing rtpproxy instance . My purpose is to add new rtpproxy instance when Kamailio is running. Thanks in advance. Any suggestion would very helpful. Thanks & Regards Pintu

kamailio not forwarding 407
by David Villasmil 26 Sep '18

26 Sep '18

Hello guys, I have an almost default config, the box behind kamailio sends out the register, it is forwarded to the provider, which replies with 401, this gets forwarded back to the box which sends out the REGISTER with credentials and all works well. BUT when calling out, INVITE is sent to kamailio which is properly forwarded to the provider. The provider replies with a 407 and this 407 is NOT forwarded back to the box. Any ideas why? I can't figure it out! Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337 ᐧ

Hey, I've been using the Dispatcher module with great results. But now, i want to be able to have some gateways to belong to more than one group set. To achieve that, i'm duplicating the Gateway in the Dispatcher's table and give it a different group set. However, if i do this, Dispatcher will do repeated probing to this gateways. Is there any way to avoid this or to achieve the same result in a different way? Best Regards

No dispatcher failover
by Gertjan Wolzak 26 Sep '18

26 Sep '18

Hello Kamailions, I want to send traffic to an Asterisk box but when that box fails traffic should be routed to the second Asterisk box. The dispatcher params are as follows: # ----- Dispatcher params ------ modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_ping_interval", 20) modparam("dispatcher", "ds_ping_reply_codes", "class=2;class=3;class=4") modparam("dispatcher", "ds_inactive_threshold", 4) modparam("dispatcher", "ds_ping_latency_stats", 1) modparam("dispatcher", "ds_probing_threshold", 1) My dispatcher.list is: #DBBS PBX # SBC's 1 sip:ip_address_sbc:5060 0 0 weight=100 #PBX 2 sip:ip_pbx_01:5060 0 10 weight=100 2 sip:ip_pbx_02:5060 0 5 weight=100 Verry simple request route: request_route { if (is_method("OPTIONS")) { sl_send_reply("200", "OK"); exit; } #Call from SBC to PBX #Get gateway from dispatcher list if($si=="ip_address_sbc1" |$si=="ip_address_sbc2" ) { ds_select_dst("2", "8"); $var(new_uri) = "sip:" + $tU + "@" + $dd + ":5060"; $ru=($var(new_uri)); route(RELAY); exit; } # Call from pbx to SBC # Get sbc ip from dispatcher list ds_select_dst("1","4"); $var(new_uri) = "sip:" + $tU + "@" + $dd + ":5060"; $ru=($var(new_uri)); route(RELAY); } When I send a call to the kamailio its routed correctly to the first pbx. But when I kill the asterisk process on the first pbx, an invite is still send by Kamailio to the first pbx. Maybe I am assuming incorrectly that when the dispatcher does not react to the ds_ping it will be set to "inactive" and not be selected by the ds_select_dst command... Or am I thinking to easy and do I need to configure some actions in the failure route? Pretty sure I'm doing something wrong, but cant see where and have not been able to find the information. Tips are appreciated. Rgds, Gertjan Wolzak

onsend_route showing wrong answer after forking
by Aymeric Moizard 26 Sep '18

26 Sep '18

Hi, I'm experimenting "onsend_route" with "onsend_route_reply=yes" to improve my logs. I was surprised to see that "onsend_route" doesn't always display the "forwarded" answer after negative final answers. The documentation seems to indicate that this route will execute only if "the received reply is sent out". -as I'm forking, the final 6xx answer is not "forwarded" immediatly... and I guess this is the reason it doesn't show. Here comes a real strange use-case: With forking enabled, only the last answer will appear in the "onsend_route", however, in some case, this is NOT the answer being forwarded. Example: 1/ receive 603 decline from branch1 2/ a CANCEL is sent on branch2 3/ a 487 Request Terminated is received on branch2 What happens: 1/ onsend_route is showing "487 Request Terminated" 2/ 603 Decline is forwarded (as expected) The documenation say: "If set to 1 (yes, on), onsend_route block is executed for received replies that are sent out. Default is 0." This doesn't look to be correct. (either the doc, or the code?) Is there any possibility to install a log in the script that would log ALL *exact* replies being sent: 1/ the real forwarded ones 2/ and also the ones sent by kamailio directly. May be this is possible with some "event_route"? Tks a lot! Aymeric -- Antisip - http://www.antisip.com

Dispatcher Questions
by Duarte Rocha 26 Sep '18

26 Sep '18

Greetings, I have some questions about Dispatcher0s modules general behaviours. Can Dispatcher use two tables to read values from? If I can't use two tables, is it possible to read them from a Mysql View? I want to be able to have a Gateway belonging to more than one Gateway Set. By doing so, in the table, the gateway will be repeated but with different groups. How will the probing work in this scenario? Will the Gateway be probed multiple times? Thanks for your help. Cheers

TM Module timing question
by Igor Olhovskiy 25 Sep '18

25 Sep '18

Hi! A bit lost in timers for TM module Idea is following I want to have dial timeout for 30 seconds, but only if I received 100 Trying in reply to INVITE. If no 100 Trying is received - I want timeout to be like 2 seconds. 100 Trying is indicator for me, that other side is alive. As I got, fr_timer and fr_inv_timer is not what I’m looking for.

htable event routes behavior
by Володимир Іванець 25 Sep '18

25 Sep '18

Hello all, I have following configuration: 1. Htable which loads from MySQL DB and has autoexpire setting. *modparam("htable", "htable", "tl_connect_users=>size=4;autoexpire=120;dbtable=some_htable")* 2. Regular *route[SOME_ROUTE]* with sole logic. 3. *event_route[htable:mod-init]* 4. *event_route[htable:expired: some_htable]* I use while loop in *event_route[htable:mod-init]* to extract stored values from htable, assign them to *$var(some_variable)* and call *SOME_ROUTE* to perform some action for all of them on Kamailio start up. *SOME_ROUTE* has *$sht(some_htable =>$var(some_variable)) = "enabled"* line to add expired value back to the htable. The pboblem is when* event_route[htable:expired: some_htable]* triggers *SOME_ROUTE*. Values are not being added to htable. Hovewer if I will try to manipulate values for key_name or key_value by adding some character new item will be insert to the htable. Does anybody know if behavior is correct when exactly same value can not be inserted back to htable on it's expired event? Thanks a lot!

Help with kamailio/freeswitch
by David Villasmil 25 Sep '18

25 Sep '18

Hello guys, I know this is kamailio's mailing list, but I'm getting no answer on freeswitch, and i thought someone here has probably done this is the past. I have a proxy in front of freeswitch. I want freeswitch to use the proxy for everything including the termination to my provider. If I configured the gateway like this: <include> <gateway name="myprovider"> <param name="username" value="username" /> <param name="auth-username" value="username"/> <param name="password" value="password" /> <param name="register" value="true"/> <param name="caller-id-in-from" value="true"/> <param name="from-domain" value="myprovider.com"/> <param name="realm" value="myprovider.com"/> <param name="register-proxy" value="myproxy.domain.com"/> </gateway> </include> The registration works properly, the REGISTER goes to the proxy like REGISTER sip:myprovider.com;transport=udp SIP/2.0 and the proxy forwards it fine, and registration works great. But when i try to call via this gateway, the call goes STRAIGHT to the provider! If, on the other hand, i configure my gateway as: <include> <gateway name="myprovider"> <param name="username" value="username" /> <param name="auth-username" value="username"/> <param name="password" value="password" /> <param name="register" value="true"/> <param name="caller-id-in-from" value="true"/> <param name="from-domain" value="myprovider.com"/> <param name="realm" value="myprovider.com"/> <param name="register-proxy" value="myproxy.domain.com"/> <param name="proxy" value="myproxy.domain.com"/> </gateway> </include> Registration does NOT work, because the uri is: REGISTER sip:myproxy.domain.com;transport=udp SIP/2.0 Because there is no registrar on that proxy!

Issuse with http_client and config_file

Hi I am trying to use http_client with a config_file set but can't get it to work .Have tried on 4.4 and 5.1 with the same results (Debian 9 packages).

Include parameters in replies
by Duarte Rocha 21 Sep '18

21 Sep '18

Greetings, I need to to include some routing information (Two Id's, example "id_in=10;id_out=72") to be read later by Kamailio in every Request (Except the first one and in every Reply. For the requests, i'm including this info as parameters in the Record-Route and i'm reading it later in the Route Headers. For replies i thought about using the Via header. I'm using subst_hf() and i'm having success adding the parameter to Via in the requests. However, it does not seem the best idea since i breake the routing when i add the parameter. I wanted to avoid using custom headers for this since i can't really be sure that they won't be erased by any client's CPE or endpoint. Any ideas on this ? Thanks Cheers, Duarte Rocha

re- double record route
by Wilkins, Steve 19 Sep '18

19 Sep '18

Hi Henning, Yes I do have that enabled. What is happening is that one of the providers on IOS is sending a double record route on the INVITE, but it is getting lost somewhere so when I send a 'BYE', I get a "404 not here". When I look at the SIP message I see only one of the record routes from the INVITE, therefore my assumption is, this is what is causing the 404, because everything else looks good.

occasional processing delay and UAC remote registration
by Dmitri Savolainen 19 Sep '18

19 Sep '18

Hi all. i encountered in my 4.1.5 kamailio server some inconstant issue. I have 2 listen address: addr1 for incoming SIP requests and as source addr for remote registration (via UAC module) addr2 for incoming SIP requests only uac config for regs: modparam("uac", "reg_keep_callid", 1) modparam("uac", "reg_random_delay", 120) modparam("uac", "reg_retry_interval", 300) modparam("uac", "reg_timer_interval", 40) i have response time checking tool, that send OPTIONS every second, which immedeately replied by sl_send_reply("200") without any processing. Usualy respose time <1ms. Sometimes (2-3 per day) addr1 stop to response for these OPTIONS (timeout >5sec), while addr2 continue responding with time <1ms. In kamailio.log at this moment bunch of messages like ERROR: uac [uac_reg.c:1034]: uac_reg_tm_callback(): got sip response 403 > while registering ERROR: uac [uac_reg.c:1034]: uac_reg_tm_callback(): got sip response 408 > while registering That is normal: some remotes are broken. The problem is: 1. usually these messages appearing is not the reason of problem, but all problems are while these messages in log 2. it may be on OFF peak / ON peak day period 3. in my test installation i have much more remote failure registration (X 10), and the problem is not manifested more often (but i can catch it 2-3 per day) I think adding more workers for addr1 may help (now 8 worker and 16 CPUs). But it is interesting to understand the source of this issue -- Savolainen Dmitri

Await to INVITE after REGISTER for mobile device which get awake via android/iOS notification messages
by Kristijan Vrban 18 Sep '18

18 Sep '18

Hi, now that many SIP endpoints are mobile devices which usually deep-sleep, and only get awake after Android/iOS own notification messages awake them, what are the best practices to await a a pending INVITE to such a mobile device until it REGISTER after the awake? I currently use a Asterisk a do a simple loop, trying new INVITES every second, but this is not elegant. A nice solution would be a type of queue, where the pending INVITE get send to the new location triggered immediately by the fresh REGISTER from that device to avoid any delay during call setup Kristijan

how to catch attacker using bad request line?
by Juha Heinanen 17 Sep '18

17 Sep '18

In order to be able to fail2ban an attacker that sends tons of SIP requests with malformed request lines, it would need to be possible to generate an appropriate syslog message from config file. I didn't find any sanity module param value that would turn on checking of request line syntax. Any other ideas? As an example, below is what comes to syslog when I send a request that has syntax error on request line. -- Juha Sep 17 14:46:39 char /usr/bin/sip-proxy[9458]: ERROR: <core> [core/parser/msg_parser.c:337]: parse_headers(): bad header field [(null)] Sep 17 14:46:39 char /usr/bin/sip-proxy[9458]: WARNING: <core> [core/receive.c:230]: receive_msg(): parsing relevant headers failed Sep 17 14:46:43 char /usr/bin/sip-proxy[9458]: ERROR: <core> [core/parser/msg_parser.c:337]: parse_headers(): bad header field [(null)] Sep 17 14:46:43 char /usr/bin/sip-proxy[9458]: WARNING: <core> [core/receive.c:230]: receive_msg(): parsing relevant headers failed

Forward SIP request between two Kamailio servers

Hi,? I have a simulation setup of 4 VMs in Virtual Box - two UAs and two Kamailio servers. The first UA will register to KAM1, and the second UA will regsiter to KAM2. See the Figure below. UA1<--->KAM1<---->KAM2<---->UA2 int1 int1 int3 int3 int2 int2 I would like KAM1 to forward all SIP requests destined to int3 via KAM2 and vice versa. I am aware of the routing logic in 'kamailio.cfg', but i find rather excessive. Pseudo code of what i'm trying to achieve: if (is_method("INVITE")) { if(dst_ip == int3) set_next_kamailio_server(KAM2) } Or: if (is_method("INVITE")) { if(callee is unkown) ask_kamailio_server(KAM2) } Thanks for all the help

Good evening.

remove_hf("Bla") for all requests
by Sergiu Pojoga 12 Sep '18

12 Sep '18

Hi there, Say I need to remove_hf("User-Agent") for all requests, back and forth. So I add it at the top of *request_route *section. However, replies don't seem to be affected by it. Do I really need to arm a *t_on_reply route* for this simple purpose? "Problem" with that is that *route[RELAY]* already has some *onreply_route* block doing things like *NATMANAGE *for some methods and as far as I know - only one* onreply_route* can be armed for a request? route[RELAY] { ... if (is_method("INVITE|SUBSCRIBE|UPDATE")) { if(!t_is_set("onreply_route")) t_on_reply("MANAGE_REPLY"); } t_relay(); } onreply_route[MANAGE_REPLY] { ... route(NATMANAGE); } Any suggestions? Thanks.

Missing ACC record in case of canceled call forking
by Marco Capetta 12 Sep '18

12 Sep '18

Hi All, I'm facing a strange problem of missing ACC record in case of parallel call forking. The scenario is the following: - A subscriber with 1 device registered - B subscriber with 2 device registered (B1 and B2) CASE 1: - A calls B - B1 and B2 start ringing - A hangups the call before B1 or B2 answers Kamailio generates an ACC record. CASE 2: - A calls B - B1 and B2 start ringing - B1 rejects the call sending back a 486 - B2 is still ringing - A hangups the call before B2 answers Kamailio DOESN'T generate an ACC record. We have Kamailio v5.1.4 with TM module enabled. ACC configuration is the following: modparam("acc", "early_media", 0) modparam("acc", "report_ack", 0) modparam("acc", "report_cancels", 1) modparam("acc", "detect_direction", 1) modparam("acc", "db_flag", 1) modparam("acc", "db_missed_flag", 2) modparam("acc", "failed_transaction_flag", 3) I increased debug level of TM and ACC modules and I added some debug lines as well. The difference between the two calls is that, after the CANCEL sent by A is processed by Kamailio, in CASE 1 I have the following lines: Aug 28 14:21:11 spce proxy[13188]: DEBUG: tm [t_hooks.c:258]: run_trans_callbacks_internal(): DBG: trans=0x7f5a88049198, callback type 512, id 0 entered Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_logic.c:670]: tmcb_func(): acc callback called for t(0x7f5a88049198) event type 512, reply code 487 Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_extra.h:63]: free_strar_mem(): Freeing memory, type is 2, message_index 8, index i 0 Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_extra.h:63]: free_strar_mem(): Freeing memory, type is 2, message_index 8, index i 1 Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_extra.h:63]: free_strar_mem(): Freeing memory, type is 2, message_index 8, index i 2 Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_extra.h:63]: free_strar_mem(): Freeing memory, type is 2, message_index 8, index i 3 Aug 28 14:21:11 spce proxy[13188]: DEBUG: acc [acc_extra.h:63]: free_strar_mem(): Freeing memory, type is 2, message_index 8, index i 4 Those debug lines are not printed for CASE 2. Is there any configuration I'm missing or is it a bug? Thank you very much for your support. Marco

Logging of messages generated by Kamailio itself
by Konstantin Polyakov 11 Sep '18

11 Sep '18

Hello, Could somebody help with one issue? In some cases Kamailio can send messages itself. For example, when fr_inv_timer is expired Kamailio sends 408 to the INVITE sender and CANCEL to the INVITE receiver. These two messages (408 and CANCEL) are not printed into the log and I cannot find a way to do that. There are also other scenarios when some Kamailio modules send SIP messages by its own. So is there way to print out into log all such messages? My goal is to get full message flow in the log per certain call-id. Thank you in advance. Best regards. Konstantin

Simultaneous usage of t_on_reply() and t_on_failure()
by Володимир Іванець 10 Sep '18

10 Sep '18

Hello everyone, I wanted to ask those who know if Kamailio's behavior I'm facing is expected or I should make some improvements to the configuration. Kamailio version is 5.1.0. I have a route where RTPEngine parameters are being collected and *rtpengine_offer()* is called. After that *t_on_reply("REPLY_SIP_TO_SIP");* followed by the *t_on_failure("FAILURE_SIP_TO_SIP");* are used. The idea is to process all responces except 415 or 488 from UAC as usual in *onreply_route[REPLY_SIP_TO_SIP]* and use *failure_route[FAILURE_SIP_TO_SIP]* to update SDP with *rtpengine_offer()* if necessary. *onreply_route[REPLY_SIP_TO_SIP]* just goes to *exit;* if *$rs* equals 415 or 488. This works fine with Htek phone which sends 100, 180 and then 488. But I can not see *failure_route[FAILURE_SIP_TO_SIP]* execution for calls to Zoiper which replies with 100 and immediately 415. t_on_failure(failure_route) documentation says: "Sets failure routing block, to which control is passed after a transaction completed with a negative result but before sending a final reply." and to be honest I don't really understand how lacking of responce prevents failure_route from executing. Thanks a lot!

Via header line missing
by Karlheinz Knapp 07 Sep '18

07 Sep '18

Hi, hm.... the only reason why I'm playing with kamailio is that it should be able to translate IPv6 from customer phones behind Fritz!Box (NAT) to IPv4 used by the provider (which is not able to handle IPv6). But it looks that he accept in general the packet with 2 Via lines (also with IPv6 as address) and send a normal reply. The second Via is not needed, because he have to send to the first Via. And if it really comes to trouble, I can remove it with kamailio :) If it is not possible to make a complete translation with kamailio, then I have to search again for an other solution. But still: why is this one Via line not transmitted on the IPv6 side? Only when I do some modifications it appears magically. That's not a normal behaviour in my opinion. If you or Henning can not reproduce this behaviour, then it's possible that I start TeamViewer and I can show this on our installation (only at normal working hours). Btw. I use sngrep to display all the messages, but it works stable and reliable. Best regards, i.A. Bernd

kamailio with evapi crashing on high volume
by Jayesh Nambiar 07 Sep '18

07 Sep '18

Hello, I'm using kamailio 5.1.5 with evapi. I have a node.js connecting with kamailio evapi to which I send events and also consume events based on which I do the routing. I have 8 evapi workers defined in the config. The problem is that kamailio randomly crashes on high load. I'm assuming that it is related to the evapi module as rest of the config is pretty straight forward. I could get a core file and here's the core dump: [New LWP 14042] [Thread debugging using libthread_db enabled] Using host libthread_db library “/lib/x86_64-linux-gnu/libthread_db.so.1”.

Kamailio with CGNAT
by Amar Tinawi 06 Sep '18

06 Sep '18

Hello Although my question it's not related to Kamailio directly, but i think someone could help in this strange behavior in our tests, we have some clients under private networks, where the provider of those networks implements CGNAT (NAT444) for it's customers to reach internet (Client Private IP) --->(Home router: Private to Private NAT)--->(FW with CGNAT)---------------------------->(Kamailio Proxy Public IP) Registration is performing fine, but making calls from this client had strange problem as follow: Client -------------INVITE--------------> Proxy Proxy -------------Trying---------------->Client Proxy--------------INVITE---------> Called Party The called party should send Ringing msg, but the massage get lost somewhere and didn't reach to the Proxy. Although all the IP's in sip massages are public i tried with STUN/TURN and NAThelper module solutions, but didn't help is there any way to slove CGNAT with SIP in Kamailio? Thanks in Advance

null $au
by David Villasmil 06 Sep '18

06 Sep '18

Hello, in the block: 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")) consume_credentials(); } I'm trying to print out $au, but it's coming up NULL many times, i don't get why this is. If i remember correctly, the script goes through this block twice, once when we get the REGISTER with no credentials, and once when the REGISTER comes with credentials after the challenge... is this correct? i need to know how to catch $au when the authentication is successful... help? Thanks! David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337 ᐧ

Via header line missing
by Karlheinz Knapp 05 Sep '18

05 Sep '18

Hi, we want to use kamailio as a IPv6 to IPv4 proxy. IPv4 to IPv4 bridging with NAT works. If we come from an IPv6 address, the registration packet is send via IPv4 to the provider. He answers with 401 Unauthorized and one Via line in the header. On the IPv6 side was no Via line in the packet. So I tried to add one line by hand using an onreply_route and append_hf(), msg_apply_changes() To my suprise, this line does never appear, but the original Via line is now in the packet !!! If I add now additional Via header lines, they appear in the packet too. This looks realy like a bug to me. A solution is needed, because the phone does not respond to the 401 with user and password. It starts a new registration instead. Maybe I can fix it with my additional Via linem but I need the original branch ID (I think) How can I get this? Btw. we have this behaviour with 4.4.2 and 5.1.5 If I get no answer during the next 12 hours I'll try 3.3.7 Best regards

dispatcher local socket
by Евгений Голей 05 Sep '18

05 Sep '18

Hello! Kamilio version 5.1.0 Please tell me why the module dispatcher does not correctly determine the availability of destination gateways. The scheme is as follows: Kamailio (udp:XX.XX.XX.XX:5060) ----- Provider_1 -----> (sip:aa.bb.cc.dd:5060) Dest GW Kamailio (udp:YY.YY.YY.YY:5060) ------- Provider_2 -----/ In table dispatcher: setid | destination | flags | priority | attrs 17 | sip:aa.bb.cc.dd:5060 | 8 | 50 | socket=udp:XX.XX.XX.XX:5060 17 | sip:aa.bb.cc.dd:5060 | 8 | 40 | socket=udp:YY.YY.YY.YY:5060 That is, our server controls the availability of the remote gateway through two local sockets, in order to switch to the backup if it is not available through the primary Internet provider. But as I understand at the moment when determining the availability of a remote gateway, the outgoing socket does not play any role, that is, if the remote gateway is not accessible through the secondary operator (priority is less than the primary one), only the one that has priority above is always inactive. Are there any solutions to this problem? BR. Evgeniy

From URI attribute for dispatcher target
by Giacomo Vacca 05 Sep '18

05 Sep '18

Hi all, I was looking for a solution to set a dedicated From URI in OPTIONS requests to a specific dispatcher target. ds_ping_from ( https://www.kamailio.org/docs/modules/devel/modules/dispatcher.html#dispatc…) applies globally, why I needed the granularity of a single target. With these changes to the dispatcher module I get what I need: https://github.com/kamailio/kamailio/commit/3f9c38be11416f7abe5c4448088ba66… I can just add an attribute to the others, e.g. instead of *1 sip:127.0.0.1:7070 <http://127.0.0.1:7070> 0 1* something like: *1 sip:127.0.0.1:7070 <http://127.0.0.1:7070> 0 1 ping_from=sip.custom.com <http://sip.custom.com>* When the ping_from attribute is not specified, the general ds_ping_from applies and is used. This would save me from a solution like intercepting the outgoing OPTIONS and manipulating the From header. Does this approach make sense? Are there other ways already available to achieve this? Thanks, Giacomo

SCA: sca_call_info_bye_handler: no in-use callee appearance for BYE
by Asgaroth 05 Sep '18

05 Sep '18

Hi All, I've just started playing with the SCA module and am encountering an issue whereby SCA cannot seem to find an in-use appearance for the BYE message. From my limited understanding of SCA, the module, in this case, appears to be trying to track the state of the call using callid as there are no call-info headers in the signalling for it to extract and use. I call sca_call_info_update() for initial invite, 100 response, 180 response, 200 response and again for the terminating bye. When I answer the call, at the 200 ok for the initial invite, I can see sca sending a notify to the subscribed devices indicating appearance state being active. I can verify this with kamcmd sca.all_appearances. However, when I hang up the call, when sca_call_info_update() is fired for the bye message it fails with the following error message: sca [sca_call_info.c:1587]: sca_call_info_bye_handler(): sca_call_info_bye_handler: no in-use callee appearance for BYE <aor> from <from uri>, call-ID 7989c223-2ba4-1237-1888-20474786734e I cannot seem to track down where this is failing for me, or where I may be missing something in my configuration. sca.all_appearances does appear to have the entry mentioned in the failure message, there must be something I'm missing somewhere. Is there anyone out there who is using the sca module and may have a moment to assist with this issue. I have a pcap trace that I can send privately. Any assistance would be greatly appreciated. Thanks

DMQ mem leak issues
by Rogelio Perez 04 Sep '18

04 Sep '18

Hello, We're running three instances of Kamailo v5.14 as registrars handling registrations from ~2000 SIP clients, with one instance being primary and the other two as backups. The three of them are using the dmq and dmq_usrloc modules to synchronize user locations, however after a couple of days of operation the two failover instances show memory leak behaviors, with mem usage assigned to the core taking all available resources. When this happens we've noticed that: - The shared memory used by the function "sip_msg_shm_clone" spikes (from 1kb to 1.5GB). - The shared memory used by the function "dmq:worker.c:job_queue_push" also increases, but not as much (from 1kb to 1MB) - DMQ request are not being answered (with a 200 OK) by the affected instance during this memory leak, which make us think that DMQ module becomes unresponsive. A few more notes: - The failover instances are doing nothing except receiving replicated contacts. - The shared memory grows at the same rate on both instances, but the critical behavior never happens at the same time. - We are allocating 1GB memory on startup to each instance. - We store the location DB in a psql DB and we load it at startup. - We didn't find any errors in syslog, even at debug level. Has anyone experienced a similar issue who can suggest a possible solution? Thanks, Rogelio Perez Telnyx

I have not set closed_event param, because according to README, it defaults to 1.

Can't connect to local MySQL server (13 "Permission denied")

Hi, In a previous post ([SR-Users] Questions about changes between 5.0.1 and 5.0.7 <https://lists.kamailio.org/pipermail/sr-users/2018-August/102442.html> ), I reported problem to upgrade my kamailio from 5.0.1 to 5.0.7-7 level. With help from some people, it was finally fixed on my test server in my lab.

Dispatcher question
by Igor Olhovskiy 03 Sep '18

03 Sep '18

Hi! I’m having some issues with dispatcher and cannot get why it’s not working Idea is to use ds_next_dst right after ds_select_dst I’m having it like this modparam("dispatcher", "list_file", "/tmp/dispatcher.list") modparam("dispatcher", "flags", 2) # Enable dispather failover modparam("dispatcher", "xavp_dst", "_dispacher_dst_list_") … ds_select_dst(«1», «0»); … # Some extra check on $du here … ds_next_dst(); But get in logs WARNING: dispatcher [dispatch.c:2285]: ds_update_dst(): no xavp uri field in next destination record But contents of /tmp/dispatcher.list is 1 sip:172.28.0.12:5060 1 sip:172.28.0.19:5060 Can I somehow dump xavp_dst var to check if ds_select_dst is correct? kamailio 5.2.0-dev6 Regards, Igor

handle_ruri_alias() question or issue?
by Wilkins, Steve 02 Sep '18

02 Sep '18

Good Morning All, The following Incoming request came in => SIP Incoming Request: [[BYE sip:2406506175@20.20.20.20:5060;alias=10.10.10.5~55157~2 SIP/2.0 I called handle_ruri_alias(), and expected the destination and port to be set to 10.10.10.5:55157, but it was not. It was left 20.20.20.20:5060. Is my thinking correct or is there another way to set the destination and port to the alias? Thanks All!, -Steve

Having trouble associating response to message request
by Byran Carlock 31 Aug '18

31 Aug '18

Hello, I'll be the first to admit I'm a complete novice to Kamailio, but I'm learning due to necessity. I'm working on setting up Kamailio as a sip proxy (SBC?). Any help would be massively appreciated. The desired setup would be for Kamailio to as an external connection point to authenticate the connection and reverse proxy/NAT the rest of the traffic to the asterisk server, hiding internal topology as we go. Right now I'm using dispatcher with NAT and ALIAS to push connections to proxy@{PROXY IP} to proxy@{ASTERISK EXTERNAL IP}. I'm running into an issue where a "Message" is being sent, forwarded to the Asterisk server and responded to. Then Asterisk spawns a new call ID "To" the proxy rather than the original requestor which of course gets a 484 response. How can I somehow associate these two messages and complete the route?
