Jettel

Jettel Softphone has come up for iPhone based Mobile phones. Jettel Softphone lets the callers make calls through their standard Mobile phones. The iPhone dialer works just like standard Softphones i.e. it gets registered on the server and then let the authentic caller makes calls.

This softphone also turns your iPhone into a VoIP phone, so you can make cheap or even free phone calls over the internet at anytime, and from almost anywhere.
Jettel Softphone is designed specifically to leverage the iPhone's unique capabilities and easy way to make a iPhone voip call by using iPhone devices.
