in this case.
Please note that how this line is selected depends on the Config Mode and the Callee
Number received. The Callee Number is defined as the phone number specified in the
“To:” field of an INVITE message. Please refer to Section 3.3.3.1 for more information.
Calling the SIP number directly routes the call to the corresponding line immediately.
If this parameter is blank and the Callee Number equals to the SIP Number defined for this
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.
3. Forwarding to GSM
Number
If this parameter is specified, GoIP dials this phone number via the corresponding GSM
channel whenever an incoming VoIP call is received for this line. This is a fixed forwarding
method and has the highest priority. This means that the Dial Plan setting does not apply
in this case.
Please note that how this line is selected depends on the Config Mode and the Callee
Number received. The Callee Number is defined as the phone number specified in the
“To:” field of an INVITE message. Please refer to Section 3.3.3.1 for more information.
Calling the SIP number directly routes the call to the corresponding line immediately.
If this parameter is blank and the Callee Number equals to the SIP Number defined for this
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.
4. Dial Plan The Dial Plan specifies rules to modify the Callee Number before dialing it out. Each rule
is terminated with the delimiter “|”. The rule matching begins from the left to the right.
Once a match is found, rule matching terminates and the actions specified in the rule are
executed.
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
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
