Dialing rules are used to effectively determine if the received number sequence is completed, for the
purpose of stop dialing and sending out the received numbers. The proper use of dialing rules can help to
reduce the connection time of telephone calls.
The maximum number of rules that can be stored in gateways is 520. The total length of the dialing rules
table (the total length of all dialing rules) cannot be more than 3000 bytes.
The following table provides a description of typical rules:

Description
First digit timer
If a subscriber has not dialed any number within a specified time by this parameter after
offhook, the gateways will consider that the subscriber has given up the call and prompt to
hang up in busy tone. Unit: seconds, default value: 12 sec.
Inter-digit timer
If a subscriber has not dialed the next number key from the time of dialing the last number key
to the set time by this parameter, the gateways will consider that the subscriber has ended
dial-up and call out the dialed number. The default value is 12 sec, unit: seconds.
Critical digit timer
This parameter is used with the “x.T” rule set in dialing rules. For example, there is “021.T” in
the dialing rules table. When a subscriber has dialed 021 and has not dialed the next number
within a set time by this parameter (e.g. 5 sec), the gateways will consider that the subscriber
has ended dial-up and call outthe dialed number 021.
The default value is 5 sec, unit: seconds.
x
Represents any number between 0-9.
The x sign can match with any numbers. For example, the x sign can match with 1 or 2.
