Virtual call center
DCFirst Claim
1. In a call control system operative as a call center, said call center being physically distributed, a method for controlling routing of a telephone call comprising:
- receiving a call at an incoming gateway (301) of the call control system (10);
separating the call into components of a signaling channel (16) and a bearer channel (18);
signaling from the incoming gateway to a call control system that said call has been received by the incoming gateway;
determining via a call routing system (400) the termination point to which said telephone call should be delivered from incoming call information of the signaling channel (16) and from information and availability of a qualified agent at a termination point (500 or 600) to establish a selected termination point;
signaling with control signals from said call control system to an outgoing gateway coupled to said selected termination point;
causing said an outgoing gateway (308) to connect to the incoming gateway (301) via a digital voice packet connection to carry content of said bearer channel (18); and
directing content of said bearer channel (18) of said call from the outgoing gateway (308) to said selected termination point (500 or 600).

Abstract
A system and methods are provided for enabling real-time call control. with minimal requirements for dedicated telecommunications PBX and dedicated switching equipment. Dynamic call routing is handled by a network carrier'"'"'s equipment and an interface is provided at the carrier switch to dynamically redirect calls from outside of the carrier'"'"'s network. A call'"'"'s signaling channel and bearer (voice) channel are separated, allowing the voice carriage to continue to be handled by the network carrier, but the routing of the call is controlled from outside of the carrier'"'"'s network. A real-time signaling path and interface is provided into the carrier network such that the associated routing decisions and business logic can remain outside of the carrier network, while the carrier network continues to carry the voice channels.

16. A call control system comprising:
-
an incoming gateway apparatus (301) operative to receive a call from the call control system (10); an apparatus (301) configured to separate the call into components of a signaling channel (16) and a bearer channel (18); an apparatus (402) configured to determine via a call routing system (400) the termination point to which said call should be delivered from incoming call information of the signaling channel (16) and from information and availability of a qualified agent at a termination point (500 or 600) to establish a selected termination point (500 or 600); an apparatus (302) to connect an outgoing gateway (308) to the incoming gateway (301) via a digital voice packet connection to carry content of said bearer channel (18); an apparatus (403) for directing content of said bearer channel (18) of said call from the outgoing gateway (308) to said selected termination point (500 or 600); an apparatus (405) for contemporaneously signaling from a the call control system to an agent screen visual display (502 or 602) at the termination point (500 or 600) to provide call-specific information regarding the call; and an agent interface server (404) operative to provide call-specific information to the agent screen (502, 602) at the termination point (500 or 600). - View Dependent Claims (17, 18, 19)
