Installed S Class, enabled Caller ID on CO lines, I have tried adjusting the gain in system timing. The Caller ID still does not work. The local provider is using a Copper Comm Soft Switch. Do I have to program a caller ID feature key on the phone for this to work?

Only if they want to be able to scroll through calls, as long as you have it enabled it should work. I would guess that the provider isn't sending you caller ID

The caller ID is enabled from the providers switch. The caller ID still does not work with our demo kit and with a different directory number. We also put a Caller ID unit ahead of the ESI system and it is recieving the digits.

A couple (probably) stupid questions:

I'm guessing you DID enable CID in F24?

Have you called tech support to see what they have to say? If you are getting it ok ahead of the system, using an industry-standard CID box, then something is missing at the system, or something isn't lining up right.

I have cured this problem a couple of times by changing the Line Receive Volume. In most cases the volume is to hot and CID info is unreadable by the system at uncommon levels. Start by taking the LRV down 4 notches.

Just for my records who is the service provider?

How about some feedback from original poster. Did any of the above suggestions solve the problem?
