[Freeswitch-users] Need help with Video proxy-media mode

[Ken Rice]

Topology Hiding means to you hiding everything behind something... In this
case FreeSWITCH...

Proxy Media mode is for special cases where you are still proxying the media
with FreeSWITCH that is a legacy feature but is not even needed anymore.
Just use FS in the default modes and this will get you Topology Hiding.

If you don¹t want topology hiding you can use bypass media where the media
does not go thru FreeSWITCH, but you lose a pile of features by doing this
and you are effectively NOT doing a full topology hide at this point.
