July 9, 2019Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractA telephone call connection architecture is disclosed which establishes a call connection between two parties. A caller at a caller location initiates a call request to an intermediate location over a first communication network requesting a call be connected to a callee at a callee location over a second communication network. The caller location is connected to the callee location over the second communication network in response to the call request being made over the first communication network. In both a call back and call collect scenario, the caller initiates the call request to the intermediate location. However, in a call back situation, the caller is ultimately charged for the call, while in a call collect situation, the callee authorizes charges for the call.Other References
