Hi all,

We have two businesses in town. We initially had two Avaya Partner systems. We recently upgraded one of the businesses to the new Avaya phone system which I don't quite have the name of (not VOIP) (I'll call this location 1) and our other business still has its original Avaya Partner system. (location 2)

The one that has not been upgraded, location 2, has 4 Avaya Partner phone modules in our PBX closet (not sure of the correct terminology here.) Anyway, over the years certain extensions have went out and we were having problems with it so we simply took the ones that were being upgraded from location 1 and moved them to the location 2 and I installed them this afternoon. After installing them in their slots, I tested them and all work fine, I matched the wires and lines up one by one as they were on the ones I was replacing - no problem at all and all extensions are so far working fine. I noticed that the ones I'm replacing were Partner and Partner II but were not Partner ACS (which I do know supports caller ID.) All 4 phone modules on the rack are all now Avaya Partner ACS - the only one I have not changed out was the center one that has a hold music aux in and some other stuff on it.

After I install the center phone module, should our caller ID work now? The caller ID worked fine when they were at their original location before the upgrade, but now that they're installed over here we still don't have caller ID. I still have to go get the center module with the aux jack from the old place and install it, just to have it all together. Does the center piece have anything to do with caller ID?

To my understanding our telephone company has caller ID enabled and I am under the assumption caller ID is automatic on the Partner system depenedent on the telephone line. Anyway, any help you could offer would be appreciated. Who would have thought anyone ever taking Caller ID for granted, but when you have eight lines running into one building it's definitely helpful.
