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

[Salman Zafar]

Hi Razvan,
        I got it working without branching, after banging head a lot I got
to learn unforcing drops the media ports for previous rtpproxy offer/answer
and after that directing the new flow though rtpproxy flags,IP media works.
I am able to traverse from eternal to internal play media and then on
failure do external to external with media flowing between public
interfaces. Just wondering if you know this method or certify.
