POTS dial peers enable incoming calls to be received by a particular telephony
device. To configure a POTS dial peer, you need to uniquely identify the dial peer
(by assigning it a unique tag number), define its telephone number(s), and
associate it with a voice port through which calls are established. Under most
circumstances, the default values for the remaining dial peer configuration
commands are sufficient to establish connections.
To enter the dial peer configuration mode (and select POTS as the method of
voice-related encapsulation), use the dial-peer voice number pots global
configuration command. The number value is a tag that uniquely identifies the
dial peer. (This number has local significance only.)
To configure the identified POTS dial peer, use the destination-pattern string
dial peer configuration command. The string value is the destination telephone
number associated with this POTS dial peer.
When a router receives a voice call, the router selects an outbound dial peer by
comparing the called number with the number configured as the destination
pattern for the POTS dial peer. The router then removes the left-justified numbers
corresponding to the destination pattern that matches the called number. If you
have configured a prefix, the prefix is put in front of the remaining numbers,
creating a dial string, which the router then dials. If all numbers in the destination
pattern are removed, the user receives a dial tone.
For example, suppose there is a voice call with the E.164 called number of
1-310-767-2222. If you configure a destination-pattern of 1310767 and a prefix
of 9, the router removes 1310767 from the E.164 telephone number, leaving the
extension number of 2222. It will then create a prefix 9 at the front of the
remaining numbers, so that the actual numbers dialed are 9,2222. The comma in
this example means that the router will pause for one second between dialing the
9 and the 2 to allow for a secondary dial tone.
