Abstract
An approach provides interdomain traversal to support packetized voice transmissions. A centralized data store, maintained by a service provider, stores one or more user identifiers and an associated directory number. The centralized data store also stores routing information including one or more communication paths corresponding to the user identifier, wherein the routing information includes a data path or a circuit-switched path for establishing a call to the user. In response to a request for establishing the call to the directory number, the data store retrieves the routing information for use to establish the call.
