[OpenSIPS-Users] opensips and multiple rtpengine instances

[Răzvan Crainea]

The RTPengine module in OpenSIPS simply instructs the server to 
start/stop the sessions, and adds a few control flags. It does not, by 
any means, handle the RTP packets order.
The module ensures that for a specific callid, *all* initial and 
sequential messages go to the same RTPengine go to the same instance, 
if, of course, you are using the same RTPEngine set for that call.

So to be honest, I can't say I understand what's happening in your 
setup. Can you give us a few more indications?

Best regards,
Răzvan
