International priority calling system with callback features
First Claim
1. A method of completing an outgoing telephone call placed by a caller from an originating network and directed towards a destination connected to a remote network comprising the steps of:
- recognizing unavailability of at least one of telephone network resources comprised of switching capacity and transmission facilities to complete said call at said destination, said resources being under the control of said remote network;
estimating in said originating network anticipated time range before said network resources can become available;
offering said caller an option of being called back when said resources become available, said offering being carried out only when the estimated time meets a predetermined criterion;
when said callback option is exercised by said caller, calling back said caller when said network resources are about to be available within a very short time frame; and
initiating in said originating network an interconnection between said caller and said destination when said resources become available.

-
determining that said circuits are temporarily unavailable to complete said calls; computing expected time to complete each call if it were to be placed in a queue; presenting announcements to said callers indicating at least one option to complete each call; in response to signals from ones of said callers, acting on said announcements, placing the calls initiated by said callers in said queue which is comprised of a) a callback section storing information about ones of said callers to be called back, and b) a holding section comprised of calls on hold waiting to be completed initiating periodic requests for access to one of said circuits at said destination; upon accessing one of said circuits, selecting one of said calls on hold to be routed via said circuit based on a predetermined position of said call in said queue; and calling back and placing on hold one of said callers in said calling back section in said queue based on a predetermined position of said information about said caller in said queue. - View Dependent Claims (4, 5, 6)
