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?

> If a TFN owner wants to limit its area of service to Great Toronto ONLY - they can do it (by asking their RespOrg). Because the TFN owner pays for calls coming to his/her number depending on a call's origin.

> Regarding "playing" a message - this is a correct behavior because _what_ should be done in case of call being out of area of service is also configured by a request from TFN owner by its RespOrg. 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.
