Hello, I am trying to use the 3CX Skype gateway, and whenever I make a call on this trunk, I get a sound on the IP Phone's end that sounds like an old industrial fire alarm. The user I call can't hear me, either. The sound on the IP Phone's end is rather loud too. Does anyone know how to fix this? Thanks! EDIT: I am using the built in gateway template, and Skype Gateway 2.0.9919.0.
