[Freeswitch-users] Bypass media succeeds from extension to gateway but fails from extension to extension

[Ken Rice]

This is not a bug in FreeSWITCH...
Bypass Media is a special mode to allow us to act as a psuedo proxy.

Other then possibly filtering some codecs the rest of the SDPs are simply
copied across the bridge. That means if your sip devices are sending RFC1918
IPs in their SDPs then FreeSWITCH will forward an RFC1918 SDP. Why is that?
Because FreeSWITCH has no way to know where the media is actually coming
from since FreeSWITCH is not in the media path.
