[Freeswitch-users] If Bypass Media works why won't Proxy Media work?

I find it strange that I can have to endpoints get audio went using bypass media mode but the audio fails to go across endpoints if I use proxy media mode. I'm trying to pass audio "internally" on the same machine between endpoints and have be advised that a reason the audio may fail to be passed is because there is some RTP timing and IP address/port issues. However, FS has no problem "connecting" ports if i change the mode to bypass media. This gives me the impression that something is wrong with FS proxy media mode. Any comments??
