Customer changed PRI carriers due to Katrina as Bell was thier only option. We can make outgoing calls but cannot receive incoming. We verified all settings and protocols with Bell and they said everything matched: NI-2, B8zs, received digits 4, etc... Bell came out with T box and showed us where the 4 digits are coming in on the PRI circuit. They claim that they are seeing the 4 digits hit the D channel but the call does not go thru . I setup a target line 149 to appear and ring on one phone to test . When the number is dialed, it times out after 20 seconds. Any suggestions ? Confused in Chocolate City
