SDP Codec not removed with RTPengine - but with rtpproxy it worked
by Oliver Roth 23 Nov '16

23 Nov '16

Hi there I have the following problem - I need to remove a codec in the initial INVITE. This happens since I changed from rtpproxy to rtpengine. I changed all rtpproxy_manage() to rtpengine_manage(). Originating INVITE with the "clearmode" m=audio 9196 RTP/AVP 8 0 125 101 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:125 CLEARMODE/8000 a=rtpmap:101 telephone-event/8000 I do the following in the config route[SDP] { xlog(, "L_INFO", "SDP: request method $rm"); … [View More]

IMS related : ims_usrloc_pcscf : "lookup_check_received" setting is useless now
by Dragos Oancea 23 Nov '16

23 Nov '16

Hi The setting "lookup_check_received" is documented here : http://www.kamailio.org/docs/modules/4.4.x/modules/ims_usrloc_pcscf.html#id… But looking through the code I saw it's not used anymore, although it can be passed as a parameter. I was wondering if this is an accident or something intentional. I found some more details here: http://lists.sip-router.org/pipermail/sr-dev/2014-June/024371.html Cheers, Dragos

async_workers vs. async workers modparam in case of async_route()
by Alex Balashov 22 Nov '16

22 Nov '16

Hi, If I am using async_route() with delay, what is the relationship between the core async_workers parameter value and the async module 'workers' modparam? This doc change was intended to clarify it, I think: https://www.mail-archive.com/sr-dev@lists.sip-router.org/msg25002.html But it does not for me: > Number of worker processes to be started to handle the > asynchronous tasks for async_route() and async_sleep(). So, does that mean the module starts its own processes for … [View More]

log_prefix ignored in resumed routes
by Alex Balashov 22 Nov '16

22 Nov '16

Hi, I have this log_prefix: log_prefix="[$ci $mt] " Which means xlog("L_INFO", "xyz") normally results in log entries like this: Nov 22 00:29:50 allegro-4.evaristesys.com /usr/local/sbin/kamailio[27625]: [1-27702(a)10.150.20.6 1] INFO: xyz But if xlog("L_INFO", "xyz") happens to occur in a route[] block that is resumed after async_route()—I have not tested other async functions—there is no prefix: Nov 22 00:29:52 allegro-4.evaristesys.com /usr/local/sbin/kamailio[27678]: INFO: … [View More]

flags documentation
by Alex Balashov 22 Nov '16

22 Nov '16

Hi, I have this set up in my configuration boilerplate: -- flags DUMMY : 1, PDD_DAMPEN : 2, PROXY_MEDIA_SET : 3, #!ifdef WITH_NAT_TRAVERSAL SIPPING : 4, #!endif DUMMY2 : 12 -- I then use these aliases in transaction flags, e.g. setflag(PDD_DAMPEN). But I can honestly say I don't remember how I arrived at this approach. I wrote it somewhere in early 3.x days. However, when I look at the core documentation for … [View More]

Message flags preservation for replies in onsend_route
by Alex Balashov 22 Nov '16

22 Nov '16

Hi, I have -- flags BLAH : 1, DUMMY : 12 onsend_route_reply=yes route { ... setflag(BLAH); if(!t_relay()) sl_reply_error(); } onsend_route { if(is_reply() && isflagset(BLAH)) do_things(); } -- My discovery has been that isflagset(BLAH) always == FALSE _unless_ an onreply_route has been armed for the request, regardless of whether it is necessary. In other words, the following causes … [View More]

Registering Trunk help please
by Andrei Mahalean 22 Nov '16

22 Nov '16

Hello, I am having a bit of trouble finding information on how to setup a registering trunk with Kamailio. By registering trunk, I mean a trunk between a PBX and Kamailio, of say 15 DID's, where the main DID (Pilot) registers with Kamailio and all the other 14 DID are able to make/receive calls without having to register all DID's individually. If the pilot DID registration goes away, the trunk is then considered to be unreachable/down. I have seen this in the past with a Broadsoft setup, but … [View More]

Roadmap to Kamailio v5.0
by Daniel-Constantin Mierla 21 Nov '16

21 Nov '16

Hello, following the last IRC devel meeting, I am writing the summary of the main points being discussed there and what's planned to get to Kamailio v5.0. 1) Freezing should be done either before Chrismas holidays or at beginning of January 2017 to aim meeting the deadline for next Debian stable distro 2) Restructuring the source tree To be done in the weeks before freezing, so eventual fixes won't have hard time to be backported to 4.4. This means it will be done in December. Open issues: … [View More]

usage of app_mono : how to communicate results back to config file
by Pranathi Venkatayogi 21 Nov '16

21 Nov '16

Hi, I am using app_mono module and building my logic in c# app. I am unable to understand how to send the decision back to kamalio.cfg. More precisely: I would like my routing logic to allow specific user names though they are not registered as subscribers. Like: translate(a)myip.cyracom.com<mailto:translate@myip.cyracom.com> I have the logic in c# app which takes $ru and validates such that: Host is myip.cyracom.com User is translate How do I … [View More]

Is there a way to detect inactive MSRP chat sessions without using SIP session timers
by Pranathi Venkatayogi 18 Nov '16

18 Nov '16

Hi, I am using MSRP feature of Blink client. I want to track when the chat starts and ends so I can free up server resources. Apparently Blink client does not send BYE when MSRP chat window closes. It does not support SIP session timers even. So potential use of SIP session timers (sst and dialog modules) is ruled out. Only possible way is to track every message that goes through the server and keep the session alive. If no message comes within “expiry time period”, server … [View More]
