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
