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?
KR,
Oli
