To be more specific (now I'm on-site) -- Auto Attendant (Call XPress VM system) answers, and will successfully attempt a transfer to a station on the NEC system. If the station is busy / in use, CallXPress successfully interprets that and dumps the call to that station's voicemail box.

BUT, what I can't get to work is if the station is not in use (i.e. it just rings, no answer), CallXPress doesn't recognize that, it just rings forever, until approximately a 2 minute timeout passes, and then the caller is dumped back to the main greeting.

Any suggestions?

Thanks.
