Abstract

A method for routing a call to a called party who may be located at any one of plural sites which avoids delays in connecting the called party to the received call. When a call is received at a switch, a controller at the switch uses an embedded data base to identify plural sites where the called party may be located from among a multiplicity of sites to which the switch can be connected and causes the switch to initiate parallel connections from the switch to the identified sites. The received telephone call is routed through the switch to a one of the sites at which the called party responds to the initiated connections, and the initiated connections from the switch to the other of the identified plural sites are thereafter disestablished.

Claims

1. A method for routing a communication to a party who may be located at any one of plural sites, the method comprising the steps of:

(a) receiving a communication for the party at a switch;

(b) at the same switch, obtaining information on the communication;

(c) at a controller positioned at the same switch, searching a database responsive to the obtained information to identify plural sites where the party may be located from among a multiplicity of sites to which the same switch can be connected, the data base including a called party identifier to ensure that only one of the identified plural sites will answer the received communication;

(d) providing instructions from the controller to the same switch to initiate parallel connections from the same switch to the identified plural sites;

(e) in response to the initiated parallel connections, receiving a response by the party from one of the identified plural sites;

(f) routing the received communication through the same switch to the site at which the party responded to the initiated connections;

(g) verifying at the controller that the connection of the same switch to the site at which the party has responded has been made; and

(h) sending a signal from the controller to the identified sites for disestablishing the connections between the same switch and all of the sites except the site at which the party has responded.

2. The method of claim 1 wherein the communication is a telephone call.

3. The method of claim 1 wherein the communication is an electronic mail transmission.

4. The method of claim 1 wherein the step of obtaining information on the communication includes the step of obtaining an identifier of the called party from the communication.

5. The method of claim 1 wherein the step of obtaining information on the communication includes the step of providing identity information on the source of the communication.

6. The method of claim 1 further comprising the step of providing a unique communication address for the party at each site for routing the communication only to the party.

7. In a switch having a controller and a data base identifying a multiplicity of sites to which the switch can be connected, means for routing a received communication to a party who may be located at any one of plural sites comprising:

means for obtaining information on the received communication;

means for searching the data base responsive to the obtained information to identify plural sites where the party may be located from among the identified plural sites to which the same switch can be connected, the data base including a called party identifier to ensure that only one of the multiplicity of sites will answer the received communication;

means for providing instructions from the controller to the same switch to initiate parallel connections from the switch to each of the identified plural sites;

means for detecting a response by the party from one of the identified plural sites;

means for routing the received communication through the same switch to the site at which the party has responded;

means for verifying at the controller that the connection of the same switch to the site at which the party has responded has been made; and

means for sending a signal from the controller to the identified sites for disestablishing the connections between the same switch and all of the sites except the site at which the party has responded.

8. The switch of claim 7 wherein the communication is a telephone call.

9. The switch of claim 7 wherein the communication is an electronic mail transmission.

10. The switch of claim 7 wherein the means for obtaining information includes a means for obtaining an identifier of the called party from the communication.

11. The switch of claim 7 wherein the means for obtaining information includes a means for providing identity information on the source of the communication.
