[Freeswitch-users] RTP SSRC changes mid session

[Kiss Karoly]

Hello all,

I ran into a problem where freeswitch stopped relaying media in bridge mode from
leg A to leg B when the endpoint on leg A (Cisco SIP gateway) changed the SSRC in the RTP stream.
The first RTP packet with the new SSRC had the Mark bit set.

The closest I got when reading up on this issue was RFC3550 Section 8.2, which states that
and endpoint may change SSRC but must send an RTCP Bye before doing so.

In my case there was no RTCP involved.

Am I right to assume that FS stopped relaying media because the SSRC changed ?

Is there a magical switch that will tell FS not to stop relaying media in this case ?
If there is, are there any caveats ???

Using: FreeSWITCH Version 1.0.head (git-3aeaec7 2011-09-02 23-45-57 +0200)

Thanks,
