Patent ID: 8843152

Claim:
A method to maximize external network access capacity in an integrated call-server comprising: receiving a request for a circuit allocation at a first wireless media gateway; reviewing the request to determine an incoming logical trunk-group for a call incoming to said integrated call-server; reviewing a plurality of wireless media gateway lists associated with a corresponding plurality of wireless media gateways to determine call circuit availability for the plurality of wireless media gateways in said integrated call-server, wherein each of the plurality of wireless media gateways is associated with a location identifier associated with a network security gateway; connecting the incoming call to an outgoing logical trunk-group provisioned in the same wireless media gateway as the incoming logical trunk-group, if a call circuit is available; if no call circuit is available in the same wireless media gateway, then reviewing an interconnection table to determine if there are any other wireless media gateways currently provisioned with an interconnection to the first wireless media gateway; determining the availability of an interconnection between said first wireless media gateway and a second wireless media gateway within said integrated call-server responsive to said reviewing of the interconnection table; connecting the incoming call to an outgoing logical trunk-group provisioned in said second wireless media gateway; and wherein said connecting divides the load statistically equally among the available media gateways to minimize the time and cost for connection of a call from an incoming logical trunk-group to an outgoing logical trunk-group for all calls incoming to said integrated call-server.
