What is the PSTN?
PSTN stands for the Public Switched Telephone Network. Generally
this refers to the analog phone line standards that are almost
universally implemented, plus the T-Carrier trunks such as T1
lines and ISDN PRI trunks that support PBX systems. The PSTN is
constructed on a circuit switched model, as contrasted with enterprise
VoIP systems that are packet switched.
