Linphone is an easy to use, handy internet phone or Voice Over IP phone (VoIP).
This tool will enable you to communicate freely with people over the internet, with voice, video, and text instant messaging.
Linphone also complies to the SIP protocol, an open standart for internet telephony. The application should be able to interoperate with most SIP phones and proxies.
If you subscribe a VoIP to PSTN (=classic telephony) account to a telecom provider, you can reach everyone that has a "classic" phone line. However those calls are not free since PSTN networks are costly.
