Canadian traffic that goes through the US BrettD , I think in principle you have a valid point that I respect and can sympathise with.
However, in reality, lots of traffic goes through the US, whether you like it or not. And that includes Canada-Canada traffic, too; more often than many people would think.
I presume you use VoIP.ms SIP-to-PSTN services, too; are you really sure they aren't buying it from carriers through servers in the US? (I dunno the answer in case of voip.ms, but I recall CallWithUs buys calling to Canada through US-based carriers, which probably involves US servers of such carriers.)
Also, did you check where voip.ms has their main web-site and user database? IIRC, it was New York; so, all your base are belong to US, anyways.
