[Kamailio-Users] RtpProxy: start_recording()
by Iñaki Baz Castillo 06 Jul '09

06 Jul '09

Hi, I'm using start_recording() function of nathelper module. I use "-R" option in rtpproxy daemon in order not to record RTCP. start_recording() is called in route and onreply_route. After the call ends I see the following files in the recording directory: 283K 2009-07-06 13:41 1e54fbae418504a40744ad765718792a(a)212.230.19.1=38a3b929-co1782-INS001;1.a.rtp 275K 2009-07-06 13:41 1e54fbae418504a40744ad765718792a(a)212.230.19.1=38a3b929-co1782-INS001;1.o.rtp 0 2009-07-06 13:41 1e54fbae418504a40744ad765718792a(a)212.230.19.1=38a3b929-co1782-INS001;2.a.rtp 0 2009-07-06 13:41 1e54fbae418504a40744ad765718792a(a)212.230.19.1=38a3b929-co1782-INS001;2.o.rtp Some questions: - "1.a.rtp" is one direction and "1.o.rtp" the other, right? - What are the last two files (0 size)? - How to extract the audio from these files? note that the used codec could be G729, ALAW, GSM... Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Re: [SR-Users] [sr-dev] LCR/CR and prefix mask (REGEX?) [moved to SR-Users]
by Edson - Lists 06 Jul '09

06 Jul '09

I looked around... CR uses the same approach that LCR on prefix definitions (or, at least the README don't say/explain that it's different). So I went to look on REGEX module... Iñaki, this module has Your signature... let me ask You what exactly are this REGEX groups? Could I use something like: - Use RURI and recover associated "REGEX-group number"; - Ask LCR or CR to look for routes to prefix="REGEX-group number"; - proceed routing fail-over as usual...

Henning, how can I configure Kamailio to use some other path to find modules? i should make modules differently as well, right? I'll copy back the list so anyone can answer that.

[Serusers] rtpproxy: How to force it to send packets out a specific interface?
by Frank Durda IV 06 Jul '09

06 Jul '09

I am running SER/rtpproxy on some systems with multiple cores and multiple ethernet interfaces. I am running multiple copies of rtpproxy, each with an IP address associated with a particular interface, as in one rtpproxy is using em1 which is 208.33.44.3 and em2 is 208.33.44.4 which another rtpproxy listens at, while ser listens in em0 at 208.33.44.2. These three (actually ten) interfaces pass through ethernet switches and then on to a router with a default gateway of 208.33.44.1 and then off to the Internet or wherever. (In my setup, each rtpproxy has a second interface pointing into a private network, so only one side of a call appears on any given interface and five face toward the Internet.) SER+rtpproxy correctly divides RTP traffic for calls to 208.33.44.3 and 208.33.44.4 in the SDP payloads, and callers send their RTP packets to the two rtproxies IP addresses without problems. That part works just fine. The problem is that rtpproxy is using the default route for transmission, so everything that goes towards the Internet goes out via em0, so em1 and em2 don't transmit anything. This means that this one link is overwhelmed by the traffic that should have been divided across multiple links. Rtpproxy is allowing the local route table and the default route to handle the outgoing packets and so the packets are all going out the same interface. In my case, em0 was 100Mbit/sec (completely sufficient for SIP messages, while em1 and em2 were gigabit links to handle RTP, but they are getting used only in one direction. Even if em0 was upgraded to Gbit, it would still not be able to handle the potential for 2+ Gbit of data from the rtproxies. So, is there any way to force rtproxy to perform what I believe they used to call "reflector mode", where the answers go out the same interface they come in on? (This used to be common on UDP-based NFS file servers.) A number of communication programs also allow this behavior as an option, but rtpproxy doesn't appear to do it or it isn't turned on by default. Because the destinations for the RTP are out on the Internet somewhere, I don't believe I can solve this via "route" or "ifconfig" settings, but would be delighted if someone knows different or knows of a setting change in rtpproxy that will do this so that load balancing will work. The OS in question is FreeBSD 7.2, but I have the same issue on 6.2 and 6.3. Thanks in advance!

[Kamailio-Users] Branch Flag / Location Lookup
by Brandon Armstead 04 Jul '09

04 Jul '09

Hey guys, First off thanks for any help in advanced! I'm saving a nat branch flag into usrloc when the user registers, now each user has two registrations to the same username in usrloc, upon lookup("location"), inside of branch_route[] it appears only one of them have the nat branch flag set, while the other does not? Is there any case where a branch flag could somehow get mangled, or what to look for, or what may cause this? Also one other thing from a database outlook (the cflag) is equivalent on both AOR's. However again at the time of branch_route, one flag is i.e. 000800, and the other 000820, any thoughts are appreciated, thanks!
