ABSTRACT:
A telephone system architecture enabling various components of a video based telephone system to be distributed geographically yet operates as a seamlessly integrated system. A transcoding gateway provides an interface to a third generation wireless network and received video messages in a plurality of formats. These video messages are converted to a single format and provided to the video media server. The video media server can store the video messages in a message store, separated as a video component and an audio component. The entire video message can be provided to compatible equipment over the third generation wireless network. For non-compatible equipment, the audio component of the video messages can be provided.
