Hello,
Please let me know if there is any work around for this.
Details of the issue:
kamailio.cfg has this sequence in kamailio.cfg,
...... modparam("rtpproxy", "ice_candidate_priority_avp", "$avp(ice_priority)" ) ........
sdp_remove_line_by_prefix("a=candidate"); set_iattr("ice_priority", "1"); rtpproxy_manage("frwie");
I'm seeing an issue towards the bottom of the SDP message.
.... a=ssrc:738345272 mslabel:VPELrlXvdfGmtevlYLEeVm6zq4JHvI4g a=ssrc:738345272 label:VPELrlXvdfGmtevlYLEeVm6zq4JHvI4ga0 a=ice-ufrag:YJuJWr9clIJHhENw a=ice-pwd:3v1D1ShCg8xIlDZ9 a=candidate:1297581420 1 udp 659136 10.1.2.3 17534 typ host generation 0 a=candidate:1297581420 2 udp 659136 10.1.2.3 17535 typ host generation 0 a=ptime:20 \r\n a=nortpproxy:yes\r\n
The call gets rejected by UA due to an invalid (empty) line in SDP.
Very old but somewhat similar issue: http://lists.sip-router.org/pipermail/users/2008-September/019605.html
(Module authors, I'll be happy to code/test or assist in any way possible if needed.)
Just to test it, I commented the following code snippet and the call worked. But that can't be the permanent fix.
Thank you, - Deep N
