Our problem turned out to be the SP.
Just to add to what has been suggested, go on-site and check the POTS lines before the system.

IF Trunks set to ICLID...there is a 2 ring delay before it follows teh incoming call route...

It's not rocket science, but it seems another mystery was solved just by isolation and substitution. I gather the original poster just unplugged a line from the system and put his test set in its place, thus demonstrating that the ringing delay was in the carrier's network not the customer's equipment.

ISOLATE and SUBSTITUTE!

Every time I have tested it, butt set on the incoming line on monitor, call line from cell phone and listen, 2 rings and the office phone rings. I can not duplicate the problem. But the customer says it happens daily.

Have you checked ALL lines? It might work on 1 & 2, but when you hit 3 it might not..double check all lines to see if they are hitting one of the back lines.

yeah, I tried it on all lines, that was my first thought, they might be hitting the roll over lines. Not the case, and it happenes when the system is not busy, early in the morning, mid day. I though it might be because we have the four lines showing up on all phones. Like a key system. They have 9 phones. Could this cause it?

I had a similar problem for lines on an ip500 fed from a specific pairgain when caller ID was enabled on the ip500. Routing it to voicemail and back out immediately fixed the ring delay as well as made the caller ID show up. Avaya wouldn't admit it was a problem...

what do you mean "route into a voicemail and back out "
