System and method for dynamically routing communications

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.

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.
