Abstract

A call referral system (10) for use in a telecommunications network (12) that permits a called party (16) to control the number and treatment of incoming calls. The call referral system includes a switch (34) for receiving calls from calling parties(14) and for connecting the calls to the called party. The call referral system includes a routing monitor computer (40) coupled with the switch for monitoring the connection of the calls to the called party. The monitoring computer receives and stores a gate size selected by the called party indicating the maximum number of calls the called party wishes to simultaneously handle through each of its gates. The gates are comprised of single destination telephone numbers or groups of destination telephone numbers to the various destinations (17 & 18, 32).

Claims

1. A method of operating a call referral system for use with a telecommunications network wherein the telecommunications network routes a call placed to a called party to the call referral system and wherein the telecommunication network extends the call to the called party using a destination telephone number provided by the call referral system, the method comprising:

receiving and storing in the call referral system a maximum number of calls that may simultaneously use the destination telephone number;

receiving and storing alternate call-handling instructions in the call referral system;

receiving the call from the telecommunications network into the call referral system;

determining the destination telephone number for the call;

determining if the maximum number of calls for the destination telephone number would be exceeded by the call;

if the maximum number of calls for the destination telephone number would not be exceeded by the call, providing the destination telephone number to the telecommunications network in order to extend the call to the called party;

if the maximum number of calls for the destination telephone number would be exceeded by the call, executing the alternate call-handling instructions; and

automatically altering the maximum number of calls for the destination telephone number in response to a request from the called party wherein the request is received through an automated interface into the call referral system.

2. A method of operating a call referral system for use with a telecommunications network wherein the telecommunications network routes calls placed to a called party to the call referral system and wherein the telecommunication network extends the calls to the called party using destination telephone numbers provided by the call referral system, the method comprising:

receiving and storing gate assignments for a plurality of gates in the call referral system wherein one of the gate assignments indicates a particular set of destination telephone numbers that are assigned to one of the gates;

receiving and storing a gate size for each gate in the call referral system wherein the gate size indicates the maximum number of calls that may simultaneously use the destination telephone numbers assigned to that gate;

receiving and storing alternate call-handling instructions in the call referral system;

receiving the calls from the telecommunications network into the call referral system;

determining a particular destination telephone number and a particular gate size for each call;

determining if the particular gate size for each call would be exceeded by that call;

if the particular gate size would not be exceeded by that call, providing the destination telephone number to the telecommunications network in order to extend that call to the called party;

if the particular gate size would be exceeded by that call, executing the alternate call-handling instructions; and

automatically altering the gate sizes, the gate assignments, or the alternate call handling instructions in response to a request from the called party wherein the request is received through an automated interface into the call referral system.

3. The method of claim 2 wherein the particular set of destination telephone numbers is comprised of a single telephone number.

4. The method of claim 2 wherein the particular set of destination telephone numbers is comprised of toll-free numbers.

5. The method of claim 2 wherein the alternate call-handling instructions include connecting the calls to a voice message system.

6. The method of claim 2 wherein the alternate call-handling instructions include connecting the calls to a voice capture system.

7. The method of claim 2 wherein the alternate call-handling instructions include providing access to a called party database.

8. The method of claim 2 wherein the alternate call-handling instructions include connecting the calls to a facsimile system.

9. The method of claim 2 wherein the alternate call-handling instructions include connecting the calls to an alternate destination telephone number.

10. The method of claim 2 wherein the alternate call-handling instructions include queue instructions.

11. The method of claim 2 wherein the alternate call-handling instructions include queue instructions that include a time threshold.

12. The method of claim 2 wherein the alternate call-handling instructions include queue instructions that include a queue size.

13. The method of claim 2 wherein the alternate call-handling instructions include queue instructions that include connecting the call to a voice message system.

14. The method of claim 2 wherein the alternate call-handling instructions include queue instructions that include connecting the call to a voice capture system.

15. The method of claim 2 wherein the alternate call-handling instructions include queue instructions that include providing access to a called party database.

16. The method of claim 2 wherein the alternate call-handling instructions include queue instructions that include connecting the call to a facsimile system.

17. The method of claim 2 further including generating call referral statistics reflecting usage of the call-referral system.

18. The method of claim 2 wherein the automated interface uses automated voice instructions that prompt DTMF inputs from a caller.

19. The method of claim 2 wherein the automated interface is provided by a called party computer that connects to the call-referral system.

20. The method of claim 2 further comprising automatically altering one of the alternate call-handling instructions in response to a request from the called party that is received through the automated interface.
