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.

Have you checked 15-01-04 and 20-09-02 ?

Both 15-01-04 and 20-09-02 are checked.

I have a cheat sheet (for the 8100) that shows how to capture (via DIM) ISDN call setup messages. It's specifically titled "Proving it's a telco issue".

It combines text and screen captures.

I can email it if you think it still applies to the 9100.

I would bet it's a problem on the provider end. I have had a few PRI circuits where when network upgrades were made by the telco, we stopped getting CID. Took a couple calls to the right techs to finally get it working.

It would be great if you could send the cheat sheet.

I PM'd my email address.
