What's the difference between your value and premium route for USA/Canada.
Value is the greatest price we could find for Canada. This permit us to offer Canada starting as low as 1/2 cent per minute, depending on location. Our value rate is of the best quality we could find and targeted at endusers and resellers who are looking for the best wholesale prices without any volume commitment.
Premium has a flat rate of 0.01 for both USA and Canada and is routed through established and renowned tier-1 carriers always delivering the same level of quality, at a price that is a little higher than our value option. This price is intended to end-users with critical business calls or resellers who are willing to pay a little more for assured quality, but still less than other US48 tier-1 providers.
Which one to use? Best to do is to try both (value and premium) and settle for the one that best suit your needs.

We support SIP and IAX2.
Can you give me some details about these different protocols?
"The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences." (cit. RFC 3261). It was originally designed by Henning Schulzrinne (Columbia University) and Mark Handley (UCL) starting in 1996. The latest version of the specification is RFC 3261 from the IETF SIP Working Group. In November 2000, SIP was accepted as a 3GPP signaling protocol and permanent element of the IMS architecture. It is widely used as a signaling protocol for Voice over IP, along with H.323 and others.

IAX is the Inter-Asterisk eXchange protocol used by Asterisk, a dual licensed open source and commercial PBX server from Digium and other softswitches and PBXs. It is used to enable VoIP connections between servers, and between servers and clients that also use the IAX protocol.
IAX now most commonly refers to IAX2, the second version of the IAX protocol. The original IAX protocol has been deprecated almost universally in favor of IAX2
