[SR-Dev] Capture RTP packet in Kamailio module
by Cock Ootec 27 Apr '14

27 Apr '14

Hi, I'd like to develop module for Kamailio which will be working with RTP/RTCP packets. Is there any way to capture and edit RTP packet in module of Kamailio for example in module extended from *topoh*? In topoh there are two events SREV_NET_DATA_IN and SREV_NET_DATA_OUT but I didn't be able to capture any RTP packets by them. Thanks in advance for any help or useful information.

kamailio module development - udp socket support
by Cockootec Jarabee 27 Apr '14

27 Apr '14

Hi, I am developing Kamailio module as a part of my school project and I need to send some data via UDP socket from within my module. Before I try to use Unix sockets I want to ask if there isn't something implemented in Kamailio so I can use it without developing wheel. I tried to google for "kamailio module development udp socket" and so on but I cannot find anything particular. Thanks for your help in advance.

ICE=force_relay for rtpengine
by Juha Heinanen 24 Apr '14

24 Apr '14

i have played with idea of adding new ICE flag value 'force_relay' to rtpengine. if differs from ICE=force in that only existing ICE candidates of typ relay are replaced using rtpengine relay candidates. i would appreciate if owners of rtpengine module and rtpengine itself could review the patches below and if ok, commit the changes. if committed, i can update rtpengine module README. -- juha diff -c /usr/src/orig/sip-router/modules/rtpengine/rtpengine.c ./rtpengine.c *** /usr/src/orig/sip-router/modules/rtpengine/rtpengine.c Wed Apr 9 08:55:16 2014 --- ./rtpengine.c Tue Apr 22 19:09:03 2014 *************** *** 1160,1166 **** if (!val.s) goto error; err = "invalid value"; !

history-info
by Juha Heinanen 24 Apr '14

24 Apr '14

some sip user agents/proxies have started to use history-info header(s) instead of diversion header(s) to carry diversion information. i didn't find any history-info header related pvs in wiki nor any h-i related stuff in parser. there is requirement in sip proxy to be able to map between h-i and diversion headers. any suggestions on how to proceed with this? -- juha
