The incoming line was provided by Callcentric, using their “free” inbound US DID program – the same number that is used for the US incoming line for Project Fax. Note that calls in pass-through mode use G.711u in the USA as compared to G.711a in Australia, and setting the incorrect mode can result in call quality degradation due to transcoding.

I started Project Fax in recognition of this, as a way to remember one of the technologies, but sadly from the few faxes I have received, it seems I might be too late. The death of voiceband modem communications is slowly but surely happening.
