I am running Cisco IP Communicator with a UC_540. I have configured the UC_540 for the IPC Extension with the following specs.
MAC 5427.1E0A.0810 - MAC of Network Adapter on the Laptop
Phone Type - CIPC
Expansion Module - None
Preferred Codec - g711ulaw
Missed Calls - Exclude Overlay Button
First Name - BDCRemote
Last Name - H
Password - 123456
When I open IP Communicator, the application appears to register successfully, but the time is 5hrs ahead and the extension does not appear. We have been using IP Commuicator off and on for about 14 months. I have never seen this issue.
Your thoughts and wisdome are extremely appreciated!
