We have a pretty old Isoetec system, and EZ-1/36. We just signed up for voicemail service and were instructed to convert our lines to centrex lines so that it would work.

The problem we are having is trying to transfer an incoming call to a voicemailbox. We are supposed to be able to hit the Trans/con key, get a dial tone, and then speed dial a voicemailbox number. it doesn't work. We get a triple tone when we try to speed dial. Like a busy signal, but only three pulses, then it stops.

Anyone got any idea of how to make this work? We're about to "fire" our voicemail company for telling us that the whole thing was a snap. Perhaps it is, but no one seems to know how to make it work.

Thanks for any help you can provide.
