I understand your confusion. But did you not say the other circuit was T1? Apples and oranges.
The difference between what is going on at this location and the others is most likely answer supervision, not the presence or absence of a PROGRESS message.
Could something be different on this one set of trunks on the AT&T side? Certainly - mistakes happen when trunks are programmed, because they're done manually. But is it
wrong? Only if it's not programmed according to what was ordered.
If you're really interested in getting to the bottom of this, whether it's to find out why this one set of trunks is "different" than the rest (which, by the way, I personally would like to know) or just to satisfy yourself that you're not sitting on a time bomb, contact your account rep and explain that you want to know the following information for
each of your PRI ISDN circuits:
Type of Network Switch, including the software release;
Version of ISDN protocol
ordered;
Version of ISDN protocol
provisioned;
What the T303 timeouts are for each switch (the default is 4 seconds).
