Hi, did you pass over the ice stuff from webrtc to the udp side? You could strip that of with rtpengine options. Social Boh via sr-users <sr-users(a)lists.kamailio.org> schrieb am Sa., 14. Okt. 2023, 01:00: 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?

I'm maybe out of context here but i don't think you can remove ssrc headers from sdp since they are crucial in identification of the rtp streams On Mon, Oct 16, 2023, 14:41 Social Boh via sr-users &lt;sr-users(a)lists.kamailio.org&gt; wrote: Hello, in the rtpengine LOG i can see: Oct 16 06:32:53 sip1 rtpengine[146001]: DEBUG: [28vs0pbtdtu7udefti8m]: ...
