Kamailio with mohqueue module
by mark＠brightvoip.co.uk 30 Jan '14

30 Jan '14

Hi, I am developing a system using Kamailio 4.1.1 as a front-end to a group of Asterisk servers. All of the usual functionality (registations, inbound, outbound, internal calls) are fine. We need to add call queueing to the system. I looked at the mohqueue module and read that we can use mohq_process() to send inbound calls to a suitably defined queue, based on the incoming URI. My question is what is the process for managing/automating the call to mohq_retrieve() to send calls to agents? Do I need to track agents with XMPP presence, etc? Thanks, Mark Hall

Hello Andrew, I did not know this function. I am using it to determine the direction of the flow.

Hello Fred, calls are being bridged across two interfaces: one natted from the outside with one public IP and one directly connected to the Asterisk. > ----- Original Message ----- > From: Fred Posner > Sent: 01/24/14 06:55 AM > To: Kamailio (SER) - Users Mailing List > Subject: Re: [SR-Users] Kamailio behind NAT > > On 01/24/2014 09:51 AM, Andrew Pogrebennyk wrote: > > On 01/23/2014 05:12 PM, Klaus Darilion wrote: > >>> It is necessary to use the cwie / cwei flags in the rtpproxy_manage call? > >> > >> If rtpproxy uses only a single listen-IP, then these flags are not > >> needed.

Problem Re-writing RURI
by Geoffrey Mina 30 Jan '14

30 Jan '14

I am trying to manually rewrite the RURI for a certain scenario. The RURI is currently: sip:110219546496707@12.12.12.12;npdi;rate=0.000880 I want to re-write so it's just: sip:110219546496707@12.12.12.12 I have the following snippet which isn't working: xlog("L_INFO","sip:$(ruri{uri.user})@$(ruri{uri.host})"); $ru = "sip:$(ruri{uri.user})@$(ruri{uri.host})"; t_relay(); the log spits out exactly what I want, but writing the $ru variable results in: Jan 29 18:59:36 dev-sipgateway /usr/local/sbin/kamailio[23042]: ERROR: <core> [resolve.c:1733]: sip_hostport2su(): ERROR: sip_hostport2su: could not resolve hostname: "$(ruri{uri.host})" Jan 29 18:59:36 dev-sipgateway /usr/local/sbin/kamailio[23042]: ERROR: tm [ut.h:337]: uri2dst2(): failed to resolve "$(ruri{uri.host})" Jan 29 18:59:36 dev-sipgateway /usr/local/sbin/kamailio[23042]: ERROR: tm [t_fwd.c:1773]: t_forward_nonack(): ERROR: t_forward_nonack: failure to add branches Jan 29 18:59:36 dev-sipgateway /usr/local/sbin/kamailio[23042]: ERROR: tm [tm.c:1502]: _w_t_relay_to(): ERROR: w_t_relay_to: t_relay_to failed Jan 29 18:59:36 dev-sipgateway /usr/local/sbin/kamailio[23042]: ERROR: tm [t_reply.c:1067]: run_failure_handlers(): ERROR: run_failure_handlers: Error in run_top_route Any hint would be greatly appreciated.

Notice: changes to apt repositories
by Daniel-Constantin Mierla 29 Jan '14

29 Jan '14

Hello, the current server hosting the apt repositories for debian and ubuntu is scheduled for replacement. It hasn't been updated with new packages in a while. Courtesy of Sipwise, a new build system is under development and should be available in the near future. Meanwhile, we plan to clone the existing packages to another server and have them available till the new system is up and running. As all these involve operations requiring DNS change and file transfer, the repositories might be unavailable from time to time. Many thanks to Jon Bonilla that took care of building the deb packages so far and Inaki Baz Castillo for hosting the afferent repositories. Note also that all Kamailio packages for latest version are also available via the official repositories from Debian unstable (sid) - thanks to Victor Seva for the work on it. Perhaps testing will get them soon and with the next stable version, should be no longer needed to use our repositories by users of Debian. We plan to keep ours as well. Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

Regarding the sem_post problem, here is an old email from Tomasz Gebarowski which is interesting because it states that he had a sem_post issue with cdp.so which he solved by modifying the modules/cdp/Makefile. Now if we skip forward to right now, I notice that cdp.so COMPILE and LINKS for me with no errors and I also notice that Tomasz' fix is in place, but other ims modules that also use semaphore do NOT link properly for me in ubuntu and are exhibiting the same *undefined symbol: sem_post* error Tomasz had years ago in his ubuntu compiles. I think (hope) this may be more than coincidence that these things are related??? I have tried Tomasz' fix with an ubuntu compile but I still get the sem_post error. I still think he is on to something here and I am NOT modifying the Makefile correctly. Any suggestions on specifics to test this theory are greatly welcome.

Kamailio with Asterisk
by Chirag Desai 28 Jan '14

28 Jan '14

Hi all, I'm wondering if someone can help me get a little unstuck. I followed the guide here: http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb And I now have kamailio running, but I have two problems. Number 1 When I do kamctl add user password and make two users, they register fine. But any attempt to call between the users times out. Number 2 Anytime I have my kamailo.cfg file begin as #!KAMAILIO #!define WITH_MYSQL#!define WITH_AUTH#!define WITH_USRLOCDB#!define WITH_ASTERISK I am unable to start kamctl. I get the following error. ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed If I run kamailio I get ERROR: bad config file (3 errors) The moment I remove the define lines at the start, kamctl starts fine, but I can't authenticate with asterisk. Any ideas? Thanks Chirag

ser-0.9.6 bug report
by David Binderman 28 Jan '14

28 Jan '14

Hello there, I just ran the static analyser "cppcheck" over the source code of ser-0.9.6 It said many things, including 1. [parser/parse_uri.c:566] -> [parser/parse_uri.c:568]: (warning) Variable 'state' is reassigned a value before the old one has been used. 'break;' missing? Source code is case 'r': case 'R': b=p; state=PR2_R; default: state=URI_PARAM_P; Suggest add missing break. 2. > [parser/parse_uri.c:624] -> [parser/parse_uri.c:624]: (warning) Variable 'state' is reassigned a value before the old one has been used. 'break;' missing? > [parser/parse_uri.c:628] -> [parser/parse_uri.c:628]: (warning) Variable 'state' is reassigned a value before the old one has been used. 'break;' missing? > [parser/parse_uri.c:631] -> [parser/parse_uri.c:631]: (warning) Variable 'state' is reassigned a value before the old one has been used. 'break;' missing? > [parser/parse_uri.c:636] -> [parser/parse_uri.c:636]: (warning) Variable 'state' is reassigned a value before the old one has been used. 'break;' missing? Duplicates.
