Curley Cord... I did some more testing into the CID issue that we've been discussing and here's what I've determined thus far:
a. C.O line 002 (in this particular group of telephones) DOES CID correctly on the PRIME station, where the lines are set to Appear and Ring. You must let the phone ring at least twice before you answer.
Lines 001 & 003 would not show CID info on ANY set, but I can see no reason why CID would work on one line but not on the other lines; on the same new trunk card. Therefore I'm assuming (yes... DANGEROUS I know!!) that CID service simply did not get purchased for all of the trunks. If I cannot verify this with the LEC, I'll check it myself the next time I'm on-site. But my money's on the "missing" service.
b. If you transfer Line 002 from a ringing station, the CID info transfers with the call (even if the station's lines are not set to APPEAR AND RING). Actually, if you answer the call from a non-ringing station, and transfer it, the CID info transfers to the ringing station. I'm assuming again (yes again ... DANGEROUS I know!!) that the CID is appearing because the call is now ringing on a station.
c. The CID info, where it's working correctly, will display BEFORE you answer the call on any Ringing station. Which leads me to a question...
Another group of telephones on the same system have four different C.O lines, and these lines will soon have CID service. This group's calls are answered by a Call Pilot (Auto-Attendant). I've set the lines into the Call Pilot to ring twice before answering. So... when the Call Pilot answers, and then transfers the call, will the CID info transfer to the ringing station?
As always, thank you for taking the time to answer questions on this forum.
