[SR-Users] RTPProxy issue?

[Igor Potjevlesch]

I reviewed again a call trace and I can be more precise: a RTP packet comes
with a new SSRC and the Marker bit set to "True". This packet is properly
forwarded.

 

Then, just after this packet, another RTP packet containing a new SSRC with
the huge timestamp and the Marker bit set to "True" is coming from the UA. 

The RTPProxy stops forward since this packet.

 

Regards,

 

Igor.

Hello,

 

Thank you.

 

Just to let you know, the RTPProxy is running in bridging mode.

Regards,

 

Igor.

Hello,

 

I discovered an issue related to the handling of "timestamp" and/or "Marker
bit" with rtpproxy (I use the latest Extension 20081224).

 

The call-flow is the following: one UA places a call to A and put this call
on hold. Then, the same UA call another number B. Individual streams are ok.

When the UA tries to transfer A with B, the RTPProxy receive a RTP packet
with a huge timestamp and the Marker bit set to "True".

 

Just after this RTP packet, RTPProxy stop forward the RTP packets from A to
B. B to C is still working.

 

Anyone have an idea?

Regards,

 

Igor.
