I'd have to read the anti-spoofing laws to see what they say exactly; the number you want to send is not one associated with the trunk group originating the call, and so quite a number of switches will ignore it anyway... but the real problem is the one the other respondants are assuming around: you said "T-1", not "ISDN PRI". I'm not 100% certain, but I don't believe you *can* send CNID down a T-1; the span protocols don't provide a way to do it, the way ISUP does, I don't think. Since the near end-office doesn't have any way to take CNID from the channel, it sets whatever that channel is datafilled with on it's switch as the CNID. If your span *is* a PRi, then the problem might be technical (AT&T 5E's typically won't let you "forge" CNID; DMS-100's will -- or at least they did years ago; haven't looked lately), or administrative. If the latter, I'm not sure whom you'd beg to, but since it's Verizontal, good luck. Cheers, -- jra -- Jay R.
