Figure 7-3 Dial Plan Settings
The function of elements allowed in a dial plan are described in the table below:
When a user dials a series of digits, the dial-plan rule is tested for a possible match.
If a match is made, the dialed sequence is transmitted. If no match is made, the
dialed number is blocked and the user will hear an error tone.
A dial-plan string cannot include spaces between elements. Dialed sequences that
are longer than specified in a dial-plan rule are truncated after the number of
specified digits. For example, if the dial-plan rule is “011x” and “0115678” is dialed,
only the digit sequence “0115” is transmitted.
