Edge Proxy, how is it supposed to work?
by Daniel Tryba 17 Aug '15

17 Aug '15

The documentation for outbound contains sample configs for edge proxy and registrar configs: http://kamailio.org/docs/modules/4.2.x/modules/outbound.html I tried to implement these but I don't see anything happen concerning the outbound module. What is supposed to happen to make it work? The main problem I have is that calls for the endpoints coming in from the registrar fail to get past the loose_routing check and fail with a 500 in the default case of the switch. the R-URI contains username/externalip/port from the endpoint, there is 1 route header (containing the edgeproxy ip) but no username/flow-token. So per http://kamailio.org/docs/modules/4.2.x/modules/rr.html#loose-route-id loose_routing returns false: "If a Route: header is found, the function returns 1 and behaves as described in section 16.12 of RFC 3261. There is only one exception: If the request is out-of-dialog (no to-tag) and there is only one Route: header indicating the local proxy, then the Route: header is removed and the function returns FALSE." How should the Path header look when registering? According to http://kamailio.org/docs/modules/4.2.x/modules/path.html#idp3043008 there should be a flowtoken inserted, this is not the case. Just a plain Path: <sip:ip;lr> is added. So when is outbound required? Can anybody confirm that the examples work?

rtpengine rewrite sdp for second time
by Virmantas Variakojis 17 Aug '15

17 Aug '15

Hi, I have a situation like this: I have kamailio with 3 NIC's. I'm sending INVITE to first provider over NIC1. Before sending INVITE I use rtpengine_manage to rewrite sdp body with IP that is on NIC1: rtpengine_manage ("replace-origin replace-session-connection direction=intvlan direction=prov1 ICE=remove"); If first provider fails i want to send INVITE for the same call to second provider. But if i use like this: rtpengine_manage ("replace-origin replace-session-connection direction=intvlan direction=prov2 ICE=remove"); or (because ip of prov1 is allready set): rtpengine_manage ("replace-origin replace-session-connection direction=prov1 direction=prov2 ICE=remove"); rtpengine ignores my changes as said in documentation: "The direction must only be specified in for initial SDP offer; answers or subsequent offers can omit this option." and if I try to set ip like this: rtpengine_manage ("replace-origin replace-session-connection media-address=X.X.X.X ICE=remove"); SDP body is doubled: it leaves old values and adds the new one. What i'm doing wrong or how can I rewrite SDP for second time? Thanks in advance for answer!

multi-process not multi-threading
by Ali Taher 14 Aug '15

Hello, Can you please help me to well understand this statement : Kamailio is a multi-process application not multi-threading Does this mean that if we have a machine with one processor of 8 cores , kamailio cannot process more than 1 call at the same time ? Any help would be appreciated. Regards, Ali

Hello all, Always fun integrating with proprietary pbx's... is there a way that is "generally accepted" as handling hold invites from devices such as Mitel or Toshiba? We're not proxying the media, so these devices are trying to send an Invite to the endpoint when calls are placed on hold.

Problems investigating a crash in the siptrace module (4.3.1)
by Sven Neuhaus 13 Aug '15

13 Aug '15

Hi, we're experiencing crashes in the siptrace.so module with Kamailio 4.3.1. I looked at the core dump with gdb but it complained about missing debugging symbols so all I could see was that it called do_action() before branching into an unknown function in the siptrace module. I then installed the kamailio-dbg package to get the debugging symbols. This had the weird effect that get the error "Cannot access memory at ..." in GDB and no longer see *any* function names (previously only the names in the siptrace module were missing. Any idea whats going on? # gdb /usr/sbin/kamailio core GNU gdb (GDB) 7.4.1-debian Copyright (C) 2012 Free Software Foundation, Inc.

Hey guys, I've been pulling out my hair for a few days trying to get SCTP with Kamailio working in CentOS 7... with no luck at all. When attempting to start Kamailio via the 'kamctl start' command I get the following error: INFO: Starting Kamailio : ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed When attempting to start Kamailio via the 'systemctl start kamailio' command, I get the following: Job for kamailio.service failed.

kamailio as SIP Agent
by Sandeep Chakravarthi 12 Aug '15

12 Aug '15

Hi, We have a requirement with one of our telco We are using asterisk in our servers and we are planning to implement SIP-I protocol and we choosed kamailio for it. In Kamailio website, i came to know that kamailio will be supporting both SIP-I and SIP-T protocols Below is what we need and pls confirm whether it is possible or not? Asterisk PBX <-------> Kamailio <--------> Telco MSC Telco will be forwarding the calls to kamailio on sip-i protocol and kamailio server has to forward the calls to our Asterisk server by converting sip-i to standard sip protocol Similiarly Asterisk will be initiating sip call to kamailio server and kamailio server should convert it into SIP-I and should forward the call to Telco MSC 1. I am able to establish the SIP trunk [sending OPTIONS from asterisk and kamailio acknowledges with 200 OK] between Asterisk and Kamailio using dispatcher module in kamailio and sip.conf in asterisk. How to establish the SIP trunk between kamailio and telco MSC? [Generally MSC will act as SIP server and kamalio should send OPTIONS packet and MSC will acknowledges with 200 OK] My telco MSC has only provided me the MSC SIP IP and there were no username/passwords provided. Means i need to use IP based authentication for the SIP Trunk establishment. In Kamailio how to achieve it? Please help and any suggestions/feedback will be highly appreciated and thankful Regards, Sandeep

sdp manipulation in connection with rtpengine_offer/answer calls
by Juha Heinanen 12 Aug '15

12 Aug '15

it was not clear to me based on rtpengine module readme if rtpengine_offer/answer are same kind of sdp manipulation functions as, for example, sdpops module functions, i.e., will rtpengine functions pass to rtpengine the sdp as it is after possible earlier sdpops function calls and will possible sdpops functions calls after rtpengine function call keep on manipulating the sdp returned from rtpengine function call. -- juha

RTPProxy incorrect port 0 in reply from rtp proxy

Re: [SR-Users] LCR Routing - Cost based routing
by DanB 12 Aug '15

12 Aug '15

Hi Alexandru, Well the concept is simple: on INVITE, you will issue a special format evapi request. You will receive the list of suppliers in the reply (which is received in a separate route) and you continue processing from there. These suppliers are simple tags so your creativity will be the limit of what you can do with them - eg: direct ip addresses received or tags of suppliers which you can further translate with drouting module or any alias related one. For more information on LCR please find this year's presentation on Kamailio World (which I strongly recommend to be attended): https://www.youtube.com/watch?v=Hsvcwleb-fY You can also find the kamailio configuration which I have used in the worshop here: https://github.com/cgrates/cgrates/tree/master/data/tutorials/kamevapi/kama… Let me know if further questions (or join our irc or mailing list so we do not create too much noise here).

Help with sip balancer
by Bruno 11 Aug '15

11 Aug '15

Hello, i'm on my first try with kamailio. I need to build a SIP balancer that should keep SIP registration from VoIP provider and route the calls to the asterisk boxes where an IVR will take care to answer. Here's my network topology: +---> [asterisk1] [public_ip] | 10.50.10.131 [router] <---NAT---> [kamailio] <---+ 10.50.10.1 10.50.10.120 | +---> [asterisk2] 10.50.10.132 In my setup i planned to use UAC and DISPATCHER modules. I started from the "kamailio-basic.cfg" and added some extra lines to handle UAC and DISPATCHER. All is working fine when i do a test call from a softphone inside network 10.50.10.0/24. When a call is coming from the sip carrier, troubles occurs because asterisk boxes are sending their internal ip in SDP. I understand that i need to rewrite SDP in that case, but i actually don't know how/where. I've attached kamailio configuration and a sip trace taken with sngrep where the problem is visible. For security reasons, i would like to force the RTP through RTPProxy. I'm missing something, and need your help me to understand my errors. Best Regards, Bruno

Trailing newline with {re.subst,expression}

11 Aug '15

I'm unable to get rid of the \n in "multiline" content of a var. xlog("var: $var(sdp)"); $var(sdp)=$(var(sdp){re.subst,/^a=rtcp:.*//}); xlog("var: $var(sdp)"); a=sendrecv#015#012a=rtcp:31543#015#012a=X-foo:bar becomes: a=sendrecv#015#012#012a=X-foo:bar Using the s flag results in no substitution at all, /^a=rtcp:.*//s should result in a=sendrecv#015#012 according to http://www.kamailio.org/wiki/cookbooks/4.3.x/transformations#resubst_expres… Is this a bug or a feature? If it is a feature, how to get rid of the newline (without additional regexps substitutions).

force_send_socket/$fs behaviour when binding to INADDR_ANY
by Alex Balashov 11 Aug '15

11 Aug '15

Hello, When binding Kamailio to 0.0.0.0, Kamailio no longer recognises any specific IP address homed on the system as being a "socket" for purposes of forcing traffic out of any specific interface (i.e. setting $fs), or any other purpose for which ingress and egress "sockets" are tracked (e.g. double RR). As I understand it, this is because Kamailio considers only addresses explicitly specified via the 'listen' core config directive to be valid "send socket" arguments. Kamailio _will_ accept addresses already attached to the interface if it is bound interface-wise, e.g. listen=eth1:5060 but not when addresses are added to the interface without restarting the proxy: # ip addr add dev eth1 172.30.110.10/24 Aug 10 17:31:35 centosity6 /usr/local/sbin/kamailio[28627]: WARNING: pv [pv_core.c:2285]: pv_set_force_sock(): no socket found to match [udp:172.30.110.10:5060] Is there any straightforward way to modify this behaviour, so that it would be possible to dynamically add addresses to existing physical interfaces and get Kamailio to utilise them as if they were bound at boot time?

Here is the output from the log file 3(3711) DEBUG: <script>: return value = 30 -----> $avp(i:10) 5(3713) WARNING: dialog [dlg_handlers.c:1426]: dlg_ontimeout(): timeout for dlg with CallID '1-3743(a)192.168.1.100' and tags '37431' '37401' 5(3713) DEBUG: dialog [dlg_hash.c:832]: dlg_unref(): unref dlg 0x7f32ee941140 with 2 -> 0 5(3713) DEBUG: dialog [dlg_hash.c:832]: dlg_unref(): ref <=0 for dialog 0x7f32ee941140 5(3713) DEBUG: dialog [dlg_hash.c:320]: destroy_dlg(): destroying dialog 0x7f32ee941140 (ref 0) 5(3713) DEBUG: dialog [dlg_hash.c:336]: destroy_dlg(): removed timer for dlg 0x7f32ee941140 [773:2813] with clid '1-3743(a)192.168.1.100' and tags '37431' '37401' Here is my config. file related to dialog module: #!define DLG_FLAG 4 loadmodule "dialog.so" modparam("dialog", "dlg_match_mode", 2) modparam("dialog", "default_timeout", 3600) # 1 hour timeout modparam("dialog", "db_mode", 0) modparam("dialog", "hash_size", 2048) modparam("dialog", "dlg_flag", DLG_FLAG) modparam("dialog", "default_timeout", 3600) # 1 hour timeout modparam("dialog", "timeout_avp", "$avp(i:10)") if (is_method("INVITE")) { #$var(rv) = perl_exec("max_allowed_time"); $var(rv) = 30; $avp(i:10) = $var(rv); xlog("L_DBG", "return value = $var(rv)\n"); setflag(FLT_ACC); # do accounting setflag(DLG_FLAG); } Maybe i am missing some configuration related to the dialog module. Any help is very much appreciated. Thanks.

Handling a non-standard SIP port
by Jean-Marie Baran 10 Aug '15

10 Aug '15

Hi, This is a question for the sake of comprehension, as I actually solved the problem with a workaround. I am trying to get Kamailio working with a third party SIP provider. The SIP server of this provider pings my Kamailio with OPTIONS messages. Being located in a sub-network, the SIP messages are relayed to a router (not a SIP router, just a gateway to the Internet) which is not listening/sending on port 5060 but on 13377. When Kamailio answer to OPTIONS, it send back the message to the router on the port 5060 which is wrong. Here is the topology: *Kamailio* *Router* *SIP Server* /my.sip.domain 174.37.217.1 197.17.144.4/ | | ? <-------------------- 5060 | | 5060 <---------------- 13377 | | | 5060 ----------------−> 5060 | | | | X | You can see that, Kamailio answers to the wrong port, but I think this is somewhat coherent since the SIP message says that the port 5060 is in use. But still, I would have liked that the correct port was used: *Kamailio* *Router* *SIP Server* /my.sip.domain 174.37.217.1 197.17.144.4 / | | ? <-------------------- 5060 | | 5060 <---------------- 13377 | | | 5060 ---------------−> 13377 | | | | ? --------------------> 5060 | But I do not understand where Kamailio is supposed to find the correct port. Below are the transport frames, and SIP frames. Kamailio receives: Internet Protocol Version 4, Src: 174.37.217.1 (174.37.217.1), Dst: 172.16.8.61 (172.16.8.61) Source: 174.37.217.1 (174.37.217.1) Destination: 172.16.8.61 (172.16.8.61) User Datagram Protocol, Src Port: 13377 (13377), Dst Port: sip (5060) Source port: 13377 (13377) Destination port: sip (5060) OPTIONS sip:my.sip.domain:5060 SIP/2.0 Via: SIP/2.0/UDP 197.17.144.4:5060;branch=z9hG4bKb9340cb29ba From: <sip:197.17.144.4>;tag=1797904074 To: <sip:my.sip.domain> Date: Mon, 10 Aug 2015 10:01:51 GMT Call-ID: c7f38580-5c817680-b94-38512c6(a)197.17.144.4 User-Agent: Cisco-CUCM10.5 CSeq: 101 OPTIONS Contact: <sip:197.17.144.4:5060> Max-Forwards: 0 Content-Length: 0 ...and then sends: Internet Protocol Version 4, Src: 172.16.8.61 (172.16.8.61), Dst: 174.37.217.1 (174.37.217.1) Source: 172.16.8.61 (172.16.8.61) Destination: 174.37.217.1 (174.37.217.1) User Datagram Protocol, Src Port: sip (5060), Dst Port: sip (5060) Source port: sip (5060) Destination port: sip (5060) SIP/2.0 200 OK Via: SIP/2.0/UDP 197.17.144.4:5060;branch=z9hG4bKb9340cb29ba;received=174.37.217.1 From: <sip:197.17.144.4>;tag=1797904074 To: <sip:my.sip.domain>;tag=b27e1a1d33761e85846fc98f5f3a7e58.de7a Call-ID: c7f38580-5c817680-b94-38512c6(a)197.17.144.4 CSeq: 101 OPTIONS Allow: INVITE,ACK,BYE,CANCEL,INFO,OPTIONS,REFER,SUBSCRIBE,NOTIFY Accept: */* Accept-Encoding: Accept-Language: en Supported: Server: kamailio (4.3.1 (x86_64/linux)) Content-Length: 0 We see clearly that the port is wrong here. But in the received SIP frame, everything suggests that the correct port is 5060, and I do not think Kamailio will look at the transport frame to send the response back to the correct port. Am I correct stating this ? Maybe the Via header should contain a port along with the IP address ? I solved the problem by using TCP instead of UDP, as I know that since the TCP connection is maintained, the port would be correct (because imposed by the gateway). I am sorry if the question does not directly relates to Kamailio, but any explanation here would be appreciated, as I am a student trying to learn how all this is working :) Cheers, Jean-Marie.

rtpengine disabling offers of rtcp
by Daniel Tryba 10 Aug '15

10 Aug '15

Maybe a bit offtopic, but I can't find a rtpengine mailinglist and know the Sipwise guys are reading this list. Since upgrading to 4.2.x and rtpengine instead of rtpproxy I'm seeing problems with calls being terminated by upstream provider after a bit more than 5m. The INVITE process looks okay, the only difference with before as far as I can see is the rtcp attribute in the SDP body. According to http://kamailio.org/docs/modules/4.2.x/modules/rtpengine.html#rtpengine.f.r… and https://github.com/sipwise/rtpengine rtcp offering can be disabled. But neither rtcp-mux-demux nor rtcp-mux-accept have any impact on the adding of the a=rtcp:port attribute in SDP. rtpengine_manage("trust-address replace-origin replace-session-connection rtcp-mux-accept ICE=remove"); or rtpengine_manage("trust-address replace-origin replace-session-connection rtcp-mux-demux ICE=remove"); have no effect op the INVITE to the upstream. kamailio: 4.2.5 rtpengine: 4.1.0.0+0~mr4.1.0.0

Debian/jessie and 4.3.1 default config doesn't work
by Daniel Tryba 10 Aug '15

10 Aug '15

It looks like the compile defaults of the ctl and mi_fifo module and the default kamailio.conf/kamctlrc conflict. kamailio tries to open: /tmp/buildd/kamailio-4.3.1+jessie/debian/kamailio/var/run/kamailio//kamailio_ctl /tmp/buildd/kamailio-4.3.1+jessie/debian/kamailio/var/run/kamailio/kamailio_fifo and will fail to run, unless explicitly set to conf paths are set to /var/run/kamailio/kamailio_(ctl|fifo)

Running Kamailio 4.3 on Debian 8.1 and systemd
by Grant Bagdasarian 10 Aug '15

10 Aug '15

Hello, I just installed the latest stable release of Kamailio (I believe 4.3.1) on a debian 8.1 system using the install guide (http://www.kamailio.org/wiki/install/4.3.x/git). Starting kamailio didn't work using /etc/init.d/kamailio start. I got the following error: # /etc/init.d/kamailio start [....] Starting kamailio (via systemctl): kamailio.serviceFailed to start kamailio.service: Unit kamailio.service failed to load: No such file or directory. failed! After some googling I found out I have to add a new file named kamailio.service to the /etc/systemd/system/ directory. Kamailio.service: [Unit] Description=Kamailio SIP Server [Service] Type=forking PIDFile=/var/run/kamailio.pid ExecStart=/usr/local/sbin/kamctl start ExecRestart=/usr/local/sbin/kamctl restart ExecStop=/usr/local/sbin/kamctl stop [Install] WantedBy=multi-user.target Now I can start kamailio using the command: service kamailio start Is this the correct way of doing this? Does the file need any changes? Regards, Grant
