3. Using rtpengine:
According to rtpengine NG protocol, "offer" supports:
"sdp-media-remove": ["video"]
However, I cannot find a way to pass this parameter via Kamailio's rtpengine
module.
Tried to add flag sdp-media-remove=video to the rtpengine_manage() but it
doesn't work.
Environment:
- Kamailio version: 6.0.6
- rtpengine version: 13.5.1.6
You can enable debug logging on rtpengine and see what it has to say
about what it receives from Kamailio when you do this.
In general: With these versions, you should be able to use the
"extended" 2-argument syntax for rtpengine_offer/_answer/_manage, by
putting the branch value (which you need anyway) as second argument,
which allows you to use this syntax directly, for example:
rtpengine_manage("replace-origin RTP/AVP ... sdp-media-remove=[video]",
"auto-next");
"auto-next" is to use the generated branch value in a branch route, and
to use the value from the header in a response. Depending on your
scenario and config you may have to use different values (rtpengine must
be able to match an answer to the corresponding branched offer).
Cheers
