Abstract
A call from a calling party (12) is routed to at least one called party (14, 16, and 18) in accordance with the network preference of the calling party while taking into account the network capability of the called party. The calling party initiates an attempt to the called party over a preferred network (32) by first querying a database (40) containing records, each indicating the network capability of a corresponding called party. If the called party has the capability of receiving a call on the preferred network, the call is routed over that network. Otherwise, the call is routed over an alternate network (30) on which the called party has the capability of receiving a call.
