Suposidly Windows Moble actually has the capabilities to use VOIP but when the cariers get it they shut that capability down. There are some cabs out there that will actually re-enable that capability and you can set the phone to use either the actual carier or if it has web access to use a voip account and connect your calls that way. So if you are near a WiFi hotspot or have a data plan it can default to that and if there is not access where you are then it will default to your normal phone plan for outgoing calls.

Unfortunatelly, most VOIP software uses the external speakers on the HC phone, by using the windows embeded VOIP, it is supose to use the phones ear speaker just like if you were making a regular call and you would use the phone just like a regular phone without having to launch a seperate app every time you wanted to make an VOIP call.
