We are getting phone numbers from Microsoft AD in E.164 format. They show on the phone fine under Corporate Directory. There are some dialing issues but that's a separate problem that I know can be solved.
We also have a secondary field in AD for internal dials which is usually 8 digits. The field is - for example - telephone2 in AD. Questions are: 1) is it possible to replace the default e.164 shown on the phone to the internal dial string? (I think I can accomplish this by making the internal dial the default phone number in AD but this would break other things.) 2. Can I list both numbers under Corporate Directory on the phones. If yes to either question, how would I go about doing it?
