In the past, real-time voice information is sent over the Public Switched Telephone
Network (PSTN). With the Circuit-Switched Technology, every call takes up a dedicated
bandwidth. End-to-end calls are established on the basis of a sequence of dialed digits,
and the PSTN dedicates a physical path between callers. Although the telephone
equipment establishes the call path at the beginning of the call, the path may change
between calls, but not during any specific call.
