One of my customers has T1 curcuit in their pbx. They've had it for quite a while but all of the sudden, they are able to place outgoing calls but incoming calls are not ringing in to the switch.
Bell states that their channels are ringing in fine. There are no Fujitsu dealers in our city and no tech support available.
Any ideas? Is there anything that can be physically adjusted on the switch to "listen harder" , etc.?
