line, a second dial tone is generated to wait the caller to dial a phone number. Please note
that this could only happen in the Single Server mode, Config by Line mode, and Config by
Group mode since SIP registration is required.
If this parameter is blank and the Callee Number does not equal to the SIP Number defined
for this line, GoIP dials out the Caller Number according to the Dial Plan defined.
This parameter is used to define rules on how to handle a numbers received for dialing out via
a GSM channel. It is intended to modify and/or restrict (need to enable the Restricted Dial
Plan parameter)the numbers to be dialed out. Each rule consists of two sections as shown
in the syntax below.
Syntax: condition:acton
"condition" defines the format for matching with the number received. It could be a prefix
(the leading part of a number), a range (use "[...]") or a fixed length number (use "X"). If no
condition is matched and the Restrict Dial Plan parameter is disabled, the number received
will be dialed out as is.
"action" defines how to remote ("-") or add ("+") digit(s) to the number to be dialed out. If
no action is required, just leave this section blank. Please make sure that you enable the
Restrict Dial Plan parameter if you want to restrict the numbers to be dialed out. Use "|" to
separate two rules.
Here are more description on the syntax and examples.
1) Syntax: a:-b+c|
The portion on the left side ("a") of ":" specifies the prefix for matching starting from the
beginning of the Callee Number. The right portion "-b+c" is the action to be taken.
Both "-b" and "+c" are optional. "-b" means that "b" is removed from the beginning of
the Callee Number. If "b" is not found starting from the beginning of the Callee Number.
"+c" means that "c" is added to the beginning of the Number generated from the last
action. In order for this rule to be meaning, "b" must be the same "a" or the beginning
portion of "a".
Example:
Callee Number = 9262124567
Dial Plan = 9:-9+852|
Actual Number dialed = 85226124567
2) Syntax: a[b-c]:-d+e
"b-c" specifies the range of a single digit. Together with "a", they form a prefix for rule
matching. "a" can be a single or multiple digits. "-d+e" are the actions to be taken as
described in the previous syntax.
Example: 913[5-9]:-9+86|
In this rule, Callee Numbers starting with 9135, 9136, 9137, 9138, 9139 meet the prefix
requirement. The first action is to remove the first digit "9" from the number and then
append "86" to the beginning of the number. If the Callee Number is 913601234567,
the actual number dialed is 8613601234567.
3) Syntax : XXX...XXX: |
This syntax monitors the length of the number to be dialed out. Each "X" represents a
single digit. If a prefix is known, X's can be replaced by the prefix. This rule restricts
the length of the phone number to be dialed out provided that the Restricted Dial Plan
parameter is enabled.
Example:
Dial Plan: 13XXXXXXXXX: |
This rule monitors the number dialed with the starting prefix of 13 and a length of 11
digits. Only phone numbers in this format are accepted and dialed out.
The syntax defined about can be mixed with others to form a dialing rule.
