i guess, the question is, if i have a Toronto TN as the CLID, and the TFN is listed in Toronto, then why wouldn't it complete,  Doug mentioned it was IP based blocking.  but then why when we change the CLID to a US based TN, it works no problem?

thanks

A CLEC which received a call to a TFN does SS7/TCAP request to its TF lookup provider in order to find out to where the call should be sent (which IXC - long distance carrier) to. If no carrier for originating area of service returned - then a type of message preconfigured on TFN's record must be played back to a caller.
