Hello,
are you executing rtpengine_manage() before or after removing
the codec?
Cheers,

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
