I am having trouble getting the Caller ID to work. The customer has added caller to 5 lines that are DID numbers for 5 users. We upgraded to the 206EC cards and all of the lines and sets are on these newer cards. There are two cabinets and the lines and sets are are spread around the 2 cabinets.
Two of the numbers are providing caller ID and the other 3 are not. There are working and non-working lines/sets on the 4 different cards. I cannot find anything that the working or non-working have in common. They are all using the same style of phone. There are no restrictions, #302 on any of the sets.
I have swapped a good line with a bad line and the caller ID works on neither phone at that point. Does anyone have any ideas for me? Please and thank you.
