We currently have several Polycom RealPresence Trio 8800 devices and a couple of them have some odd issues with dialing externally. One of the phones will be able to dial externally but then it randomly seems to "break" and when we try dialing externally, we get a fast busy signal. Right now, the only way to fix this is to restart the phone and then it's a matter of time before it "breaks" again. Internal calls still work but the issue seems to be with calling external. Any suggestions?
