POTS (plain old telephone service, or basic telephone service)—The dial
peer associates a physical voice port with a local telephone device. The key
commands you need to configure are the destination-pattern and port
commands. The destination-pattern command defines the telephone number
associated with the POTS dial peer. The port command associates the POTS
dial peer with a specific logical dial interface, normally the voice port
connecting your router to the local POTS network.
VoIP—The dial peer associates a telephone number with an IP address. The
key commands you need to configure are the destination-pattern and
session target commands. The destination-pattern command defines the
telephone number associated with the VoIP dial peer. The session target
command specifies a destination IP address for the VoIP dial peer. In
