Thank you to answer.
this is my SDP annex (no ice o related stuff):

I think I can eliminate a=extmap lines and maybe other lines but i
don't really know where I have to put *sdp_remove_line_by_prefix*
function//in the script/

Hi,
did you pass over the ice stuff from webrtc to the udp side? You could
strip that of with rtpengine options.

Hello,
I'm trying to solve a problem with calls WebRTC/UDP. I think is a
fragmentation problem because udp/webRTC calls works without
problem. The INVITE from Kamailio to the UDP device not receive
any type of answer.
I'm trying to reduce the SDP annex size using:
|sdp_remove_line_by_prefix|
for some lines unsuccessfully. Maybe I don't know where put this
function in the script.
Or, is there another way to solve this issue?
Thank you in advance
Regards
