17.4.2 Dial Plan Rules
A dial plan defines the dialing patterns, such as the length and range of the digits
for a telephone number. It also includes country codes, access codes, area codes,
local numbers, long distance numbers or international call prefixes. For example,
the dial plan ([2-9]xxxxxx) does not allow a local number which begins with 1 or
0.
Without a dial plan, users have to manually enter the whole callee’s number and
wait for the specified dialing interval to time out or press a terminator key (usually
the pound key on the phone keypad) before the NVG2053 makes the call.
The NVG2053 initializes a call when the dialed number matches any one of the
rules in the dial plan. Dial plan rules follow these conventions:
• The collection of rules is in parentheses ().
