In this paper we present a novel approach to video telephony where we are able to exploit the benefits of the Universal Plug and Play (UPnP) protocol: self-configuration, discovery and control of available devices connected to the network. At the time being, UPnP does not deal with Video Voice over IP (VVoIP) applications. Integrating a signaling protocol like the Session Initiation Protocol (SIP) with UPnP allows interaction between the videophone and other UPnP compliant devices, like a TV set or a media server. This interaction, for example, makes it feasible to display the caller's image on the television screen, thus allowing the user to relax on the sofa and naturally converse. Another interesting scenario is the one where the user sends to the conversation partner a set of still pictures or short video clips acquired from a UPnP media server already available in the home premises. An advantage of this distributed approach is its cost effectiveness, since it allows to reuse existing UPnP devices also in the context of video telephony. The integration between SIP and UPnP has been achieved introducing a new UPnP device, the VVoIP device, which is a SIP User Agent able to interoperate with standard UPnP MediaServers and Medi-aRenderers.
