Common call routing for multiple telephony devices

A system for allowing coordinated call processing among multiple telephony devices associated with an entity comprising:

• a) an interface;
• b) a processing system associated with the interface and adapted to:
• i) establish call processing rules for processing incoming calls to each of a plurality of telephony devices associated with an entity;
• and
• ii) for each incoming call to any one of the telephony devices:
• (1) receive a message initiated by a switching device servicing the one of the telephony devices, the message indicative of an incoming call to be terminated at the telephony device;
• (2) generate instructions defining how the switching device should process the incoming call based on the call processing rules;
• and
• (3) effect delivery of the instructions to the switching device, wherein the switching device will process the incoming call according to the instructions such that incoming calls to any of the plurality of telephony devices associated with the entity are processed in a coordinated fashion.
