Hi Pete, We handle this type of traffic for a number of US-based hosted providers and US-based clients with Canadian offices, who have the exact same problem as you. We are based in Canada. BTW, Toll Free to Toll Free is not supposed to work? and if it does, it?s by luck? so I wouldn?t rely on this. Cheers.

The challenge we've seen is that when you call some toll free numbers from those Canadian DID's the call gets blocked by the far end, presumably because the switching equipment is in the US. No issues dialing the same numbers from the US. We've attempted to deliver these calls over numerous different carriers with the same results. Talking with some of these carriers, we're told this is a known frustration and noone seems to have a way around it. The only thing that has helped even a little is if the customer is willing to use a toll free number as the Originating ANI, but even then it is spotty. We're not trying to do any sort of toll bypass or anything unsavory. Just want to be able to serve US customers who happen to also have some Canadian locations. Anyone have a solve for this? Thanks, Pete
