[SR-Users] Route Between WebSockets without rtpengine getting into the mix

[Daniel-Constantin Mierla]

Hello,

you can do nat_uac_test("64") to identify that call comes in via
websocket and after lookup("location") you can see it is going out via
websocket. If both coditions are true, then you can skip engaging rtpengine.

Cheers,
Daniel
