Have a 9100 that was installed in August with PRI. Caller ID worked for a couple months then all of a sudden stopped. Contacted Telco to investigate as no programming had changed on the system. Telco said it was fixed, but still not working. Was speaking with the PRI group today and they confirmed that CID was programmed but still nothing showing up. I have tried taking the name out of the DID tables but changed from the table name to the generic "Line 001" in the display.

Anything off the bat that I could check in programming? CID on PRI typically just works, no magic.
