Our solution is less than elegant but seems to be working. We do a
check in translations and if the source NPA is canadian and the
destination is TollFree we then punt it to a termination trunk we
have with a canadian carrier. <br>
<br>
We use Thinktel for this. They have been a solid partner and have
been easy to work with. <br>
<br>
Hope that helps<br>

<div dir="ltr">Greetings VoiceOpers,
<div><br>
</div>
<div>There are a handful of US SIP carriers who offer the
promise of doing business in Canada with Canadian DID's. 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.</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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.<br>
</div>
<div><br>
</div>
<div>Anyone have a solve for this?</div>
<div><br>
</div>
<div>Thanks,<br>
Pete</div>
