Hello,
I have tested video with FreeSWITCH and found out that video with SRTP
is broken. Without SRTP the video works fine.
I have attached a capture of the SIP SDP negotiation.
I am pretty new to FreeSWITCH so I don't know where exacly the problem is.
It looks like FreeSWITCH does not understand
m=video 2166 RTP/SAVP 125 126
and trims the additional parameters for it. You can see this in the last
line of the log.
Can somebody please check it?
Thank You, Artem Makhutov
