I. POTS dial-peer configuration
POTS is the abbreviation of the Plain Old Telephone Service, which refers to ordinary
telephone service. The POTS dial-peer configuration means to establish relationship
between the physical voice port and the local telephone device. Generally 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.
Please use the command
dial-peer voice pots
in the global configuration mode, and
use other configurations in the dial-peer configuration mode.

II. VoIP dial-peer configuration
The VoIP dial-peer configuration involves the corresponding of the phone numbers with
the IP addresses. The key configuration commands are
destination-pattern
and
session target
. The destination-pattern defines the phone numbers related to the VoIP
dial-peer, and the
session target
specifies the destination IP address for the VoIP
dial-peer.
