[OpenSIPS-Users] OpenSIPS/RTpProxy BridgeMode after failure route

[Răzvan Crainea]

Hi, Salman!

Well, this is what I was suggesting - even though you were doing 
RTPProxy per branch, you still should have closed the old/unestablished 
leg before starting a new one. So I can confirm that your approach is 
the proper one.
