New module: presence_profile
by MÉSZÁROS Mihály 21 Nov '11

21 Nov '11

Hello All, I've committed a new module named 'presence_profile' which provides UA config provisioniong according RFC6080. http://git.sip-router.org/cgi-bin/gitweb.cgi?p=sip-router;a=commitdiff;h=cd… The README describes the module function: http://git.sip-router.org/cgi-bin/gitweb.cgi?p=sip-router;a=blob_plain;f=mo… The modul is very very simple in it's current stage. The modul added only the event 'ua-profile' handling. Best Regards, Mihály Mészáros

GIT committing and backporting
by Daniel-Constantin Mierla 21 Nov '11

21 Nov '11

Hello, I put together a wiki page to help people porting patches between branches, exemplified with master and 3.2 branches -- the typical patch backporting these days: * http://www.kamailio.org/wiki/devel/backporting-to-3.2.x They are useful also for people with no write access, in case they want to try patches committed to devel branch in their local git repo clones. In additions, I added to kamailio wiki the page with guidelines for commits, trying to give the generic suggestions of how to do it in order to keep the coherence of the development: * http://www.kamailio.org/wiki/devel/git-commit-guidelines Updates and enhancements are welcome! If one has more suggestions or want to debate some of the proposed guidelines, feel free to start the discussion on the mailing list. Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com Kamailio Advanced Training, Dec 5-8, Berlin: http://asipto.com/u/kat http://linkedin.com/in/miconda -- http://twitter.com/miconda

Limiting simultaneous calls
by Mino Haluz 21 Nov '11

21 Nov '11

Hi, I was using cdrtool (prepaid table) and callcontrol to limit concurrent calls. In fact this is only limiting the outbound calls, but I would like to use another mechanism which should limit the inbound calls too. So basically to limit voice channels. So is there some reliable method/module how to achieve this? Thanks, Mino

Dropped registrar bindings with 1.5.3
by Alex Balashov 19 Nov '11

19 Nov '11

I have a 1.5.3 installation functioning as a registrar that is exhibiting a very curious, if only infrequent set of behaviours. The host is CentOS 5.x, with PostgreSQL 9.0 backing usrloc, and db_mode = 1 (immediate write-through). I have a registration handler in my initial request route that begins with a log message: ... else if(is_method("REGISTER")) { xlog("L_INFO", "... Processing REGISTER from $si:$sp for AOR $tu\n"); route(2); exit; } I've got a registrant who consistently re-registers with an expiration time of 120, so in theory they ought to be re-registering every two minutes or so. Most of the time they do. But, occasionally, I'll see a gap of 5-8 minutes go by, in which the above log message does not appear, and their registration expires so that they can't receive calls. That's not what's interesting. What's interesting is that I did a packet capture on the proxy and caught one of these scenarios. Within that ~8 minute window when the registration expired and calls were failing, the UAC actually re-registered several times, on normal ~2 minute boundaries, AND the proxy successfully challenged the request and sent a 200 OK indicating that the binding was stored! I double-checked all the parameters to ensure that the 401s and 200 OKs corresponded to the right REGISTER flow, etc. - yes, it's all correct. Is there any imaginable set of circumstances or a known bug that would cause Kamailio to successfully authenticate and affirm a registration request, while neither logging its receipt, nor, evidently, storing it to the database? I can envision a number of database failure modes that would account for the binding not actually being in the 'location' table, but that doesn't explain why the request wouldn't even be logged. That's what has me baffled.

[Kamailio-Users] Converting rtpproxy recorded .rtp file to .wav file
by Vikram Ragukumar 18 Nov '11

18 Nov '11

Hello, I used Kamailio+rtpproxy to record a session and rtpproxy outputs the following files long_file_name.a.rtp, long_file_name.a.rtcp, long_file_name.o.rtp, long_file_name.o.rtcp http://www.rtpproxy.org/wiki/RTPproxy/FAQ From the Rtpproxy FAQ above, i tried to extract the audio using rtpbreak and sox. rtpbreak -W -r long_file_name.a.rtp rtpbreak -W -r long_file_name.o.rtp The above commands generate rtp.0.0.raw, rtp.1.0.raw. Then when i run sox using sox --combine merge -r 8k -A rtp.0.0.raw -r 8k -A rtp.1.0.raw -t wavpcm -s out.wav i get the following errors : sox: invalid option -- - sox: -c must be given a number Is there a switch/anything else that i am missing ? Thanks in advance, Regards, Vikram.

Core compiled with Sctp support
by Stefan Ljung 18 Nov '11

18 Nov '11

I've downloaded sip-router 3.1.2 and have been struggling with the make commands for configuring. Compiling and installing. Can't really say that I master it. But I have finally managed to do all steps and started a example ser.cfg. One of the features I want to play around eith is the sctp transport. >From previous experiments with OpenSER I kearned that if I only specify a listen host address without transport protocol all three UDP TCP and SCTP sockets will be started. Ths time I only see UDP and TCP: Listening on udp: 127.0.0.1:5060 tcp: 127.0.0.1:5060 Aliases: tcp: localhost:5060 tcp: localhost.localdomain:5060 udp: localhost:5060 udp: localhost.localdomain:5060 I have read the c sources to verify that the sctp libs and header files are in the right places, and they are. What I could need is a tip on how to verify that my core has been compiled with sctp support. How can I see that ? In what files would there be a confimation of that the sctp feature will be compiled in? /Stefan

Problem trying to play recorded message before call
by David Candamil Santos 18 Nov '11

18 Nov '11

Hi there, guys. I hope you can help me. I use kamailio to comunicate some servers (each one with its own kamailio). When an user calls another, depending on the userID that will receive the call, the server redirects the call to the corresponding kamailio server. It works properly. Now, what I would like to do is to configure it so it plays a notification saying where the call is going to be forwarded. After reading some tutorials, I tried to get it working with rtpproxy, but after configuring it, it doesn't play the clips. I am testing it with a *.wav file. The path to the file is "/usr/local/etc/kamailio/test.wav" (it's in the kamailio directory). This is my software: Debian stable kernel 2.6.32-5-686 Kamailio 3.2.0 (GIT installation) rtpproxy 1.2.1-1 Kamailio and rtpproxy are running in the same machine. These are the log messages: -------------------kamailio.log------------------- (SEVERAL TIMES) Nov 16 12:58:10 debian-virtualbox kamailio[2076]: INFO: rtpproxy [rtpproxy.c:1415]: rtp proxy <udp:127.0.0.1:22222> found, support for it enabled (SEVERAL TIMES) Nov 16 12:58:12 debian-virtualbox kamailio[2069]: ERROR: <script>: Intentando reproducir audio -------------------------------------------------- This is the relevant configuration: --------------/etc/default/rtpproxy--------------- # The control socket. #CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock" # To listen on an UDP socket, uncomment this line: CONTROL_SOCK=udp:127.0.0.1:22222 # Additional options that are passed to the daemon.

As a side note, I've looked at how to implement the mt_match equivalent in redis and it does't look that hard using kamailio s.prefixed transformation (as you suggested) and redis sorted sets. I'll need to make more tests to check the performance, I'll share the results. Thanks! Javi > > Cheers, > Daniel > > > > Regards > > > > Javi >

Hi, I'm just using it because after reading lots of manuals and tutorials, it was the solution I thought it could work. The smartphone is outside the network. I am trying to use it over the Vodafone network. What do you suggest then? Thanks. 2011/11/14 Pavel Segeč <Pavel.Segec(a)fri.uniza.sk> > Hi, **** > > ** ** > > from your topology description I'm not sure why you are trying to use > RTPproxy when all your equipments are on private segments.
