I have configured my GPX- 2000 phones (2 of them). They both show green on the status page. I can dial out on them just fine. Problem is that when I call into the system and press the appropriate key (1 is routed to extension 101), I get the forwarding message and then the recording that the extension is not available. If I route to VM, it will then go to VM. The two extensions cannot ring each other either. Any ideas?
