Abstract

A system and method for routing an incoming call to a subscriber-selected destination number in accordance with dynamic data concerning the subscriber provided by an address book, a calendar and a presence server. A routing system routes the incoming call in accordance with a subscriber-defined routing rule associated with the originating number of the incoming call, as determined from the address book. The routing rule may specify that the incoming call be routed to a destination number associated with the current date and time, as indicated by the calendar. The routing rule may specify, alternatively or in addition thereto, that the incoming call be routed to a destination number associated with a presence-enabled service on which the subscriber is currently active. The subscriber or caller may also be alternatively notified of the routing of the incoming call.

Claims

1. A method for selectively forwarding an incoming call over a Public Switched Telephone Network (PSTN), the method comprising:

receiving the incoming call;

identifying the incoming call by originating number, wherein identifying comprises determining whether the originating number is associated with a subscriber-defined group;

retrieving a subscriber-defined routing rule associated with the originating number of the incoming call, wherein the subscriber-defined routing rule is based on said subscriber-defined group; and

routing the call over the PSTN according to subscriber-defined information including the subscriber-defined routing rule.

2. The method of claim 1, wherein the step of retrieving comprises:

matching an originating number of the incoming call with a contact number in a database.

3. The method of claim 1, wherein the step of retrieving comprises:

retrieving the subscriber-defined routing rule from a database.

4. The method of claim 1, wherein the subscriber-defined information comprises:

a contact number,

the subscriber-defined routing rule associated with the contact number,

a destination number,

a destination number associated with a time period,

a destination number associated with a subscriber presence on a client application, or

any combination thereof.

5. The method of claim 4, wherein the destination number is a home telephone number, a cellular telephone number, an office telephone number, a voice mail telephone number, or any other phone number.

6. The method of claim 1, wherein the step of routing comprises:

routing the incoming call to a destination number,

routing the incoming call to a destination number associated with a current time period,

routing the incoming call to a destination number associated with a subscriber presence on a client application, or

any combination thereof.

7. The method of claim 1, further including the step of:

identifying the incoming call as being directed to a subscriber.

8. The method of claim 1, wherein the subscriber-defined information comprises at least one subscriber entry including one or more records in one or more tables, each record comprising:

at least one contact number; and

a subscriber-defined routing rule associated therewith.

9. The method of claim 1, wherein the subscriber-defined routing rule is a default routing rule.

10. The method of claim 1,

wherein the subscriber-defined routing rule comprises a routing instruction comprising at least one of:

route the incoming call to a called number,

route the incoming call according to subscriber calendar information,

route the incoming call according to subscriber presence information,

route the incoming call to a voicemail system,

route the incoming call to a messaging system,

forward a message to a calling party,

forward a notification to the subscriber, and

disconnect the incoming call; and

wherein the notification is performed using at least one of;

a telephone service,

an email service,

a paging service,

a messaging service, or

an instant messaging service.

11. The method of claim 10, wherein one or more routing instructions are performed until the incoming call is forwarded to a destination according to the subscriber-defined information.

12. The method of claim 10, wherein the subscriber calendar information comprises:

at least one time slot; and

an associated destination number.

13. The method of claim 10, wherein the subscriber presence information includes at least one of:

a client application identifier,

a destination number associated with a client application, or

an indicator of whether a subscriber is currently using a client application.

14. A system for selectively forwarding an incoming call, the system comprising:

a receiver operative to receive the incoming call;

a database comprising subscriber-defined information including at least one contact number and at least one routing rule associated with the at least one contact number;

a search unit for determining from the database a first routing rule corresponding to an originating number of the incoming call, wherein the first routing rule is based on a subscriber-defined group associated with the originating number of the incoming call; and

a routing unit for routing the incoming call via a Public Switched Telephone Network (PSTN) according to the first routing rule.

15. The system of claim 14, wherein the subscriber-defined information further comprises:

a destination number,

a destination number associated with a time period,

a destination number associated with a subscriber presence on a client application, or

any combination thereof.

16. The system of claim 14, wherein the receiver is further operative to identify the incoming call as being directed to a subscriber.

17. The system of claim 14, further comprising:

a calendar database of subscriber calendar information including

at least one time slot; and

an associated destination number.

18. The system of claim 14, further comprising:

a presence server providing subscriber presence information including at least one of;

a client application identifier,

a destination number associated with a client application, or

an indicator of whether a subscriber is currently using a client application.

19. A system for selectively forwarding an incoming call, the system comprising:

an address book database including at least one contact number and at least one routing rule associated with the at least one contact number;

an incoming call identification unit operative to identify an originating number of the incoming call, wherein the originating number is associated with a subscriber-defined group;

an address book search algorithm operative to determine a first routing rule corresponding to the originating number, wherein the first routing rule is based on said subscriber-defined group;

a calendar server including at least one time slot and an associated destination number;

a presence server including at least one client application identifier and an associated destination number; and

a routing unit operative to route the incoming call over a Public Switched Telephone Network (PSTN) to a destination number determined by the first routing rule.

20. The system of claim 19, wherein the incoming call identification unit is further operative to identify the incoming call as being directed to a subscriber.
