Hi,

Configured freeswitch as a media gateway between sip and web clients.

When video call initiated from Sip client to web-rtc clients, audio sdp is dropped when responding 200 ok to sip client after getting 200 ok response from webrtc clients. where as video sdp is fine in 200 ok.

From the logs found "marking rejected media" might causing issue. but not getting clue for what is causing issue for rejected media. Enclosed complete log for reference.
