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

Betreff: Re: [SR-Users] SDP Codec not removed with RTPengine - but with rtpproxy it worked
Hello,
are you executing rtpengine_manage() before or after removing the codec?
Cheers,
Daniel

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
