Dial plan functions
Number match
Dial terminator
In areas where variable-length numbers are used, you can specify a character as the dial terminator so
that the voice gateway can dial out the number before the dialing interval expires. The dial terminator
identifies the end of a dialing process, and a call connection is established based on the received digits
when the dial terminator is received. The voice gateway does not wait for further digits even if the longest
match mode has been globally configured.
Maximum number of local numbers or call routes found before a search process stops
This function enables you to define the maximum number of qualified local numbers or call routes to be
found before a search process stops. Even if the number of local numbers or call routes meeting call
requirements is greater than the defined maximum number, the system matches against the local numbers
or call routes that are found in the search according to the configured maximum number.
Number match mode
You can specify a match mode, either longest match or shortest march.
For example, you have configured two destination numbers 0106688 and 01066880011 on the device
respectively.
When a subscriber dials 01066880011:
• If the device is configured to use the shortest match mode, the dialed number matches 0106688.
That is, the device establishes a call connection to 0106688 at the remote end, without processing
the last four digits 0011.
• If the device is configured to use the longest match mode, the dialed number will match
01066880011. That is, the device establishes a call connection to 01066880011 at the remote end.
When a subscriber dials 0106688:
• If the device is configured to use the shortest match mode, it matches 0106688.
• If the device is configured to use the longest match mode, it waits for further digits. After the dial
timer expires, the device ignores the configured longest match mode, and uses shortest match mode
automatically to establish a call connection.
When a subscriber dials 0106688#, if you configure the longest match mode and a dial terminator of
a pound sign (#) on the device, the device ignores the configured longest match mode and uses shortest
match mode to establish a call connection.
Number match policy
A number match policy can be in either service-first mode or number–first mode.
If the number-first mode is applied, a dialed number matches first against numbers and then local service
numbers or the service feature codes (when the service feature switch is enabled). For example, if a local
service feature number is *40*1234 and the number *40 is configured for a local number or call route,
*40*1234 dialed by a subscriber first matches the number *40 (*40 is dialed out as the called number),
and the local service corresponding to the local service code *40*1234 is not triggered.
