Abstract: A method of establishing secure groups of trusted contacts with access rights in a secure communication system. The method includes establishing secure groups of trusted contacts in the secure communication system; storing information corresponding to the trusted contacts of a secure group as a secure group in a database; and determining access rights of the secure group and storing the access rights in the database with the stored information corresponding to the secure group.

Abstract: A communication system including one or more end points, each end point interconnected to a wireless network. The communication system also includes a media network system, the network system contains a registration server for registering device IDs of the end points in the communication system, a database for storing device IDs, one or more media servers for routing calls between end points and a signaling server for selecting one or more media servers to route a call between end points in the communication system based on an algorithm that evaluates one or more predetermined conditions.
