Fring is a VoIP (voice over
internet) app that allows you to make 2-way video calls, voice calls and live
chat for free, from your phone or iPod.
It offers video calls to other
Fring users on any advanced smartphone over both 3G and WiFi, and allows you to
connect with your friends on Fring, Google Talk™, MSN® Messenger, Yahoo™!, Facebook
and Twitter! It can also act as a SIP client.
Fring provides a fringOut service
that allows users to call landline or mobile phones at very cheap rates (when
compared to those of Skype or of many SIP providers), while maintaining high
audio quality.
There are developed applications
for Android and iOS mobile devices.
