ICS 7750 - Unexplained numbers displayed on incomming calls

We are seeing random, unexplained numbers displayed on our IP 7960 phones on incomming calls (from outside). Display shows "Message from 9" or "Message from 345". The number varies from call to call. My guess is this has something to do with CLID and how the CM on the ICS 7750 picks up incomming IDs. We do not have CLID enabled on any of our POTS lines or T1. This is not effecting system functionality, however it is a cosmetic issue that annoys some users.
