I have a user with a M2616 phone. The user has her extension and rollover extension on key 00 and 01. The user also has their supervisors extension on key 14 and xmwa on key 13. Anytime the user receives a call on their line the Caller ID works. But if the user receives a call on the line that's on key 14 the Caller ID does not display. How can i resolve this?
