[Freeswitch-users] [Missing local host] in proxy media mode

Mon Oct 15 22:31:45 UTC 2018

Yes, I am using mod_g729 and proxy media mode and it works. Just wanted to
know, why should I avoid proxy media mode at all? In scenario where I use
proxy media, I don't want to use any FS processing on channel, just to flow
from one ip to another.
