POTS is the abbreviation of the Plain Old Telephone Service, which refers to ordinary
telephone service. The POTS dial-peer configuration means to establish relati onship
between the physical voice port and the local telephone device. General ly we only
need to configure two commands: destination-pattern and port. The command of
destination-pattern is used to define phone numbers related to POTS dial-peer, and
the command of port connect the POTS dial-peer with an actual voice port which is
usually the voice port connecting the router to the local office. Furthermore, prefix
should be configured for the outgoing PBX subscribers.
