Bingo :-) It's the PRI code that does it. If it's any consolation, that code wasn't in the mainline as long as I was with PRI :-P It's actually even worse than you describe. It allows you to set the bit that says that the calling number has been validated by the network. The justification for the change was to allow the bank to set a single outgoing number on the PBX. It may very well be true that this is what they intended to do. It also allows you to avoid paying long distance fees by spoofing the outgoing number as a local number. Numbers that are already validated avoid the billing code. Edit: Just realized that I may be wrong. The code I work on was for the SL-100. I can't remember if Meridian shared that code or not. I think they did, but it's long enough ago that I just can't remember.
