I've had a few systems with 408 cards where the Caller ID will stop working on a trunk, usually not all, just one. A system reset would resolve the trouble, I then tried just reseating the 408, that did as well. Today had a call with 5800 phones with the 8PUB-2 with the trunk option having the same thing, no CID on just the 1st trunk. The customer reset the Cable Co.'s ATA, still no CID. I reseated the 8PSUB then it was good. This has happened with different Cable Co.s, I believe they're always Arris ATAs.

I wonder if the 408 and 8PSUB-2s use the same circuitry components for the trunks - and is this a somewhat common occurrence? With some customers it may be 2 - 3 time a year it seems.
