mrjoe,
On my Panasonic phone:
1) I note in the general menu
Initial setting=>Caller ID edit=>Auto edit = (select ON)
2) I can control the CID displayed by finding any call on the CID that is listed on the phone, then I press the edit button to cycle through different CID display styles that I want to keep. Select the display style that you want. I think your calls should now display the way you would like to see them.
I don't know if your model works in the same manner. Hope this helps.
