I installed a new Avaya BCM 50 6.0 with IP1230'S. I have PRI with prime line as I/C with routing table,dest. 9. My customer accesses their call log and wants to use the Dial back feature. With prime line set as I/C the dial back isnt working.Is there any setting that invoke the route of a caller ID Log? Or is this feature only available with other primes?
