ABSTRACT:
A method and apparatus for efficiently utilizing resources in a switched telephone network by providing call treatment at the closest available resource to the calling party preventing holding up network connection through to the terminating location if resources are not available at call termination equipment to handle a call. The selected calls are locally parked pending the availability of service termination resources to handle the call. The availability of service resources at the termination is determined before a selected call is extended through the network. Advantageously while the call is parked call treatment discrimination can be performed.
