The dial-peer command always takes the argument voice. The number following it is the dial-peer tag,

and pots is the type of dial peer.

Cisco IOS software refers to a telephone number as a destination pattern because it is the destination for

an incoming or outgoing call. Enter these numbers with the destination-pattern command. A

destination pattern can include asterisks (*) and pound signs (#) from the telephone keypad, and commas

(,) and periods (.), which have special meanings. Parentheses ( () ), hyphens (-), slashes (/), and spaces

( ), which are often used to make telephone numbers easier for humans to read, are not allowed.

Notice that the commands in the examples puts the prefix 1 (used in the United States to indicate a

long-distance number) and an area code in front of the remaining numbers to complete the destination

pattern. You need to include similar codes for your country if the VoIP equipment needs to establish a

connection to the PSTN.

The Cisco IOS software does not check the validity of the telephone number. It accepts any string of

Note

permitted characters as a valid number.
