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

Mon Oct 15 09:52:20 UTC 2018

Michael, can you please explain your comment a little bit more:

"There is one exception to this rule, and that is when you are trying to
pass codecs that freeswitch does not know about, and even that case has a
better workaround than to use proxy media"

We are using proxy, because FS on windows can't support g729 and
transcoding. What is better workaround than use proxy media?

Gregor
