Hi, I guess it is after executing rtpengine_maange() – but not really sure. How can I check that?
I get a different sdp header that is going out of the gateway v=0 o=Dialogic_SDP 3975025 0 IN IP4 213.173.185.38 s=Dialogic-SIP c=IN IP4 185.49.222.198 t=0 0 m=audio 20306 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 a=fmtp:101 0-15 a=silenceSupp:off - - - - a=sendrecv a=rtcp:20307 a=ice-ufrag:UMTBynMy a=ice-pwd:63JdnvLS7cMyCQ978BA6syPmiI a=candidate:GUTMVOhP7VJyBkZg 1 UDP 2130706431 185.49.222.198 20306 typ host a=candidate:GUTMVOhP7VJyBkZg 2 UDP 2130706430 185.49.222.198 20307 typ host Incoming was v=0 o=Dialogic_SDP 3975025 0 IN IP4 213.173.185.38 s=Dialogic-SIP c=IN IP4 213.173.185.39 t=0 0 m=audio 9036 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 a=fmtp:101 0-15 a=silenceSupp:off - - - - Von: sr-users [mailto:sr-users-boun...@lists.sip-router.org] Im Auftrag von Daniel-Constantin Mierla Gesendet: Mittwoch, 16.

Cheers, Daniel On 16/11/16 10:03, Oliver Roth wrote: 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 $rm"); # remove CLEARMODE if Colt if($avp(s:todirection) =~"^MyCarrier+") { if (is_method("INVITE")) { xlog(, "L_INFO", "SDP remove: request method $rm"); msg_apply_changes(); sdp_remove_codecs_by_name("CLEARMODE"); #sdp_remove_codecs_by_id("125"); } } } This block gets hit as I can see with the xlog entry. In the sent INVITE the “Clearmode” is still in the sdp header a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:125 CLEARMODE/8000 a=rtpmap:101 telephone-event/8000 So with rtpproxy – it worked With rtpengine not any more … Any idea?
