According to Palm, all Windows Mobile-run Treo models are ready to take advantage of Microsoft Office Communicator Mobile 2007, a client designed to extend the reach of Office Communications Server 2007 to smartphones. For Palm these include the Treo 700wx and Treo 750 in North America and Europe as well as the Treo 750v and Treo 500v in Europe and other parts of the world.

Office Communications Server manages all real-time (synchronous) communications, including instant messaging, VoIP, audio and video conferencing. Microsoft said it works with existing telecommunications systems, so business can deploy advanced VoIP and conferencing without tearing out their legacy phone networks.
