The reality is we have gotten used to terrible voice quality with our
GSM and CDMA voice networks. You would be surprised what is possible.
The only issue is that depending upon your wifi hardware and device, you
may not truely be "always availabe", though most apps like CSipSimple
allow you to control that.

Using the VoIP service we offer (, you can control the
quality of the codec you want to use, all the way up to CD quality if
you wish.

Even if you use a SIP-to-PSTN (aka a "real phone number") gateway
service like Callcentric, the quality you get will generally be superior
than what you get with your normal phone system.
