[Freeswitch-users] RTP Proxy config and DTMF conversion problem

[Anthony Minessale]

just because you want to make a proxy and there is a mode with the
name proxy in it, you do not have to use it.
proxy_media mode is not going to work with inband detection because
then you are looking at the media and not really proxying it.
