In an effort to get around several 800 numbers being handed off to the same number on a PRI (i.e. 800-123-4567 and 877-234-5678 are handed off as 7500 on the PRI) is there a way to use translation rules, or some other mechanism, to match on the original called number instead of the called party number (or modify the called number to be the original called number)? GTD seems like a good alternative, but I need call routing not call reporting.
Is there any hope?
if telco is delivering alle the numbers with samecalled IE = 7500, and there is no other IE indicating what was the number called originally (check debug isdn q931), there is nothing you can do. You will need to ask telco to deliver each toll free to a different DID for your routing purposes.
