Disclosed is a system and method for routing a call to a dual mode
wireless device. In accordance with an embodiment of the invention, a
network node receives a call. The network node determines that the call
is associated with a dual mode wireless device. Once this determination
is made, the network node then selects one of a plurality of networks
(e.g., cellular network or packet-based network, such as a VoIP network)
for use in connecting the call to the dual mode wireless device. The
network node then routes the call to the dual mode wireless device via
the selected network. During the call, the network node re-routes the
call to another network if the network node determines that this other
network is now better suited for the call.
