And what "HD" codec are they using?

  Came here to ask the same thing. G.722 springs to mind as the simplest to implement that could reasonably be called "HD".

    Yes, right now we use G.722. Possibly others later.

There are a number of SIP gateways that you can use for free. You'd have to read their individual TOS and/or trust them about tracking and monetization. One of the other guys that's working on this has a list of a few providers that offer a free account and work with the WiPhone. I'll see if I can post it once he's here.

  The last time I looked at this space was ~10 years ago for a hobby project, so definitely curious if they exist.
