The RADVISION Videophone Framework is an extensible framework for IP-based Videophone Development. It helps application developers to focus on functionality rather than standard specifications. Developers working on top of the Videophone Framework do not need to be experts on VoIP standards â_" they need only be competent application developers interested in hardware integration and user interaction.

The Videophone Framework includes support of SIP for simple videoconferencing, telephony services, Presence and IM. It supports firewall/NAT traversal, security of both signaling and media, as well as a host of additional features.
