Claim:
A method of querying a policy system from any service any port (ASAP) ASAP network, the method comprising: receiving a call request associated with a call through the ASAP network; querying a policy system to determine if a first terminating gateway bridging the ASAP network and a second network may accept the call through the ASAP network and the second network before reserving any resources for the call; if the first terminating gateway may accept the call, transmitting an address of the first terminating gateway upon which to terminate the call; and if the first terminating gateway may not accept the call, determining if a subsequent terminating gateway bridging the ASAP network and a third network may accept the call through the ASAP network and the third networks before reserving resources for the call; if the subsequent terminating gateway may accept the call, transmitting an address of the subsequent terminating gateway upon which to terminate the call; and if no subsequent terminating gateway may accept the call, rejecting the call request.
