Xten's X-Lite is a free SIP ("Session Initiation Protocol") phone that allows you to use VoIP.
Xten-Lite is available for PC's, Macs and Windows Mobile devices and has a number of features.
Open standards-based design allows for maximum network interoperation and integration.
One unique ability that I have not seen before in competing products is the ability of X-Lite to seamlessly pass through NATs configurations by allowing the end user to specify a specific NAT address (the specific IP of your machine inside your LAN setup) within a SIP message.
Major features include:
Touch-tones [DTMF]

It is possible to co-brand or even private label X-Lite so that it bears the identity and look of your company or ISP.
