Hello Paul,
welcome to the Polycom Community.
The caller ID is not a functionality that can be changed on the phone so I can only suggest to post this question in a Microsoft LYNC or AVAYA forum.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
