    There was a thread about this a few weeks ago:

    ... but it didn't generate much discussion. So I'll start a new one:

    It seems to me that if, thanks to shadowmite's extraordinary efforts, WiFi will work on the 650, then it's at least theoretically possible to turn a 650 into a WiFi VOIP phone. But then again, I'm not a very technical boy. :-)

    Perhaps the experts here could enlighten us as to what it would take to make this happen?

    Imagine ... you could buy an unlocked 650 and *never register it with a cell phone carrier* ... just use it as a VOIP cellphone! Of course, this would require that:

    a) you always have access to WiFi. (For myself, this is almost true -- my company has WiFi at all of its locations, and I have it at home. That takes care of about 80% of my life) and

    b) you have VOIP service.

    Your thoughts? What are the technical hurdles? Is anyone working on this?

    Thanks in advance!

    The VOIP stuff would be easy if you have a home phone and a *nix machine. The hard part would be getting someone to develop an application that would interface with the hardware on the Treo.

    Apparently it's not possible on OS 5 (aka Garnet) because it won't wake up for incoming calls, however, it is theoretically possible to make outgoing calls. At least, that's what I heard last.

    Does anybody believe that voip would be possible on os5, or were my suspicions correct?

    What you'd need would be an API that would allow access to the mic and earpiece (done, I believe). Then you port SIP and RTP and you have outgoing. If you did some clever hook to the SMS app, you could conceivably build a method into something like Asterisk ( that would launch the outbound connection and then connect both sides. You would probably only want to use G.729a for a codec.

    Lotta work.

    Keep an eye on iPhone at I haven't tested it, but they've got a lotta cool stuff there.
