Abstract: A system and method for providing call sessions between personal communication devices (PCDs) of sender users and recipient users are described. The system includes one or more voice communication domains (VCDs) interacting with each other, and a cross-domain coordinator configured to coordinate interaction between the voice communication domains over the Global Communication Network. Each VCD includes PCDs associated with the corresponding users, and a voice communication server (VCS) deployed within the voice communication domain. The VCS is configured to control operation of the PCDs verbally by user voice commands, and to provide call sessions between a sender user and a recipient user within the same voice communication domain and between the users of different voice communication domains.

Abstract: A system and method for providing a call session in a communication environment between a caller communication device associated with a caller user and a recipient communication device associated with a recipient user are described. The system includes an automated call controller adapted for being coupled to the caller and recipient communication devices. In operation, a caller user utters a call initiation phrase in a natural language into his communication device. The system analyses the call initiation phrase, finds the recipient device in the communication environment, transmits and plays back the call initiation phrase on the recipient communication device. The system receives and analyzes a recipient reaction to recognize the recipient user intention either to accept or reject the call session, and establishes the call session between the communicating caller and recipient users.
