Abstract

A system and method for routing voice communication to an end user across multiple telephony networks are disclosed. In one embodiment of the present invention, when a caller dials a voice identity number of a user, a policy processor checks a database for information on that number. Depending on whether or not that voice identity number has an associated mapping policy attached to it, the policy processor will determine how and where the call should be routed. If there is no mapping policy associated with the number dialed, the call will be routed to that same number dialed, however, if a mapping policy does exist, the policy processor will determine to which target number the call should be routed based on a mapping of possible numbers and rules based on date and time.
