Embodiments of the invention provide systems and methods for providing an in-vehicle, multimedia, real-time communication system. According to one embodiment, a system for providing in-vehicle communication services can comprise a communications network and a vehicle user agent communicatively coupled with the first communications network, wherein the vehicle user agent publishes one or more published presence attributes. A Service Delivery Platform (SDP) can be communicatively coupled with the communications network. The SDP can provide a presence service adapted to receive the one or more published presence attributes from the vehicle user agent and update a presence profile for the vehicle user agent based on the received presence attributes. The presence attributes can comprise at least one attribute indicating information other than presence information and to provide one or more telco functions to the vehicle user agent.
