Hello, I tested a remote connection today and experienced one way audio. The remote extension registers ok and the phone rings when called and can call out. On the remote phone one can talk to the other party (internal extension) but hear nothing and the internal extension can listen but say nothing. When using tunneling the audio is 2 way, but i would like to use normal phones on remote sites so that isnt a real solution for me. My firewall test passed without faults. When i stay inside the network of my provider (telenet belgium) everything seems ok, But when the remote extension being on another network (Mobistar) i have one way audio . Tia, Christophe.
