I have a client that has a DSX 40 and caller ID is only working on line1. Lines 2,3,4. Display reads "No Caller ID Info"

Programming is correct ( just for the heck of it, we copied line 1 programming to 2,3,4)

Caller Id is present on all four lines from the provider.

I don't think it is a bad card, I never saw caller ID just stop and everything else is good.

Any thoughts on this or has anyone ever seen this?

Thanks
Walter

You have confirmed with a external caller ID box or butt set with caller ID Telco is sending the info?
Have you powered cycle the system? If not do so.

Caller Id on the line is confirmed, did a recycle of the system and have the same problem.

Have u Tried frogging the line 1 to Line 2,3,4 , if Line 2 works on Line 1 etc , Could be AC inductance or interference , it will work on a butt set or cheap caller id box , but won't work on Pbx Line card ,,cause it wasn't designed for it ,, ac inductance shoudn't be higher then 40, or 50 millivolts in Canada.
