Abstract:
A system for providing enhanced services to users of a telecommunication network having signaling traffic handled in accordance with a set of messaging protocols that support call establishment, call clearing and user-user information exchange, said network including a first user terminal operated to generate an off-hook signal in response to said first user terminal going off-hook and a plurality of second user terminals, said system comprising:a stored-program-control switch in said network having said first user terminal and said plurality of second user terminals connected thereto, said switch operated in response to said off-hook signal to generate and transmit a call establishment message;a processor in said network, connected to said switch over a voice and signaling link and operated in response to said call establishment message to establish a voice connection between said first user terminal and said processor, said voice connection comprising a first segment connecting said first user terminal and said switch and a second segment connecting said switch and said processor;said processor further operated to execute an application to provide a destination directory number;said processor further operated to generate and transmit to said switch a call clearing message including user-user information encoded with said destination directory number;said switch further operated in response to said call clearing message to clear said second segment of said voice connection while maintaining said first segment; andsaid switch further operated in response to said user-user information to extend said first segment to the second user terminal associated with said encoded destination directory number.
