When there is no match, the incoming GSM call is handled as if the Forward Number is blank.
4.
Dial Plan
The Dial Plan specifies rules to process a number dialed after the call is answered.
This
number is referred as a second dial number.
This enables a way to recognize second dial
numbers that are in a known format and dial them out immediately.
Depending on the VoIP
network connected, a second number could be an extension or an E.164 number.
Syntax 1= a:-b+c|
The portion on the left side (“a”) of “:” specifies the prefix for matching.
The right portion
“-b+c” is the action to be taken and they are optional.
When the beginning of the callee
number matches “a”, the first action “-b” is to removed “b” from the Callee Number.
The
second action “+c” is to add “c” to the beginning of the number that is produced from the first
action.
Please note that a, b, c could be a single digit or a sequence of digits and they are
independent.
Example 1:
Dial Plan = 9:-9+852|
Number received = 9262124567
Actual Number dialed = 85226124567
Syntax : XXX…XXX: |
This syntax monitors the length of the number dialed when performing second dial
operation.
Each “X” represents a single digit.
If a prefix is known, X’s can be replaced by
the prefix.
Example:
Dial Plan: 13XXXXXXXXX: |
This rule monitors the number dialed with the starting prefix of 13 and a length of 11 digits.
Once this condition is met, the number will be dialed out immediately.
The maximum length for the Dial Plan definition is 140 ASCII characters.
There is no limit on
the number of rules defined.
Each rule must be ended with the “|” character.
The rule
matching starts from the beginning and stops once a match is found.
5.
Hunt Group Mode
Forward Mode
Hunt Group operation is discussed in details in Appendix D.
Please note that Hunt Group
Mode is a property of each GSM channel and is required to be set individually.
Host - This enables the channel selected to be the Host of the Hunt Group operation.
All
clients registers and update the host on their channel status.
The host then maintains a
list of clients status and selects an idle channel to receive the next incoming GSM call via
GSM call forwarding.
Please note that each GoIP cannot have more than one Host
channel assigned.
Sharing of GSM channels between two Hunt Groups is supported.
When all channels in
one group are in use, Call Forward will be set to the Host channel of the other group.
When a free channel is available again, Call Forward is then set to the free channel
instead.
To enable this feature, the Backup Host Address must be set to the IP of the
GoIP which contains the Host channel of the other Hunt Group.
This parameter determines if the Host channel is going to be used for incoming call or not.
If the Forward Mode is set to Always, the Host channel will not be used for answering any
