Hi, I have worked with CallManager and find you question interesting. If I read your question correctly, you are trying to modify the display/label of the phone. On the 7940, I assume the phone is configured with 2 lines, if you click on line 2 a new window should pop up, towards the bottom you should see 2 edit windows one for display one for label. The label will be what is printed on the phone, the display is what internal callers will see when dialing Line 2. You probably already have done this but I thought I would answer. Good Luck.
