I'm not sure if that is the feature I'm looking at so here is the scenario. I have a Dual Mode Phone client with a TCT device name. MyMobile Identity Name is my name and the Destination Number is My Cell preceeded with a 9. When I dial our Auto Attendant (IPCC) from the Cell Phone, The CUCM sees my Cell caller ID and associates the inbound call to my 7965, turning on the remote device in use. When I call a different Auto Attendant(Same IPCC Server), through another Gateway,the call fails. I have checked the inbound CSS on both Gateways and although they are named differennt, they each have the same partitions. Can Someone explain the call flow? Where should I start for Trouble shooting?
