
CID Prefix
1. Disabled – Incoming GSM caller ID is not transmitted to SIP.
2. Use Remote Party ID – This enables the Remote-Party-ID field is sent as part of the INVITE
message. The incoming GSM caller ID is specified in the Remote Party.
3. Use CID as SIP Caller ID – This causes the CID information in an INVITE message is replaced
by the incoming GSM Caller ID.
This parameter is intended to modify the incoming GSM number.
Syntax = 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 CID number
matches “a”, the first action “-b” is to removed “b” from the CID 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:
CID Prefix = 9:-9+852|
CID Number = 9262124567
Actual CID Number forwarded = 85226124567
The parameters listed are channel dependent. This means that each channel has its own parameter settings. First select the channel desired
and then set the parameters accordingly.
3. CALL IN via GSM
This parameter enables the channel selected to accept (select “Enable”) or reject (select
“Disable”) incoming GSM calls. Enable
4. Forwarding to VoIP
Number
This parameter enables or disable an incoming GSM call to the selected channel to be
forwarded to the SIP extension specified.
If this parameter is blank, incoming GSM calls are not forwarded automatically. Instead, they
are answered with a dial tone or a voice prompt (IVR parameter enabled in the Preference
page). the device answers an incoming GSM call. This operation is called Second Dial mode.
If a SIP extension number is assigned to this parameter, a SIP call to the SIP extension is then
sent to the SIP Server or the SIP trunk address. The SIP extension must be a number that can
be recognized and accepted by the VoIP network registered.
Special Feature
Conditional forwarding is implemented to forward an incoming GSM call based on its caller ID.
To enable this feature, this parameter should be entered according the syntax described below.
1) Syntax= a>b|
“a” is a complete or portion of a number for matching with the incoming caller ID.
“b” is the number to be dialed via the VoIP network. It could be an extension number or
an E.164 number.
Example:
98765432>108|>101|
In this example, the device first try to match the incoming GSM caller ID with the number
98765432. If it is a match, the device dial the number 108. If the first rule does not
match, it will continue to the second rule. There is no matching number for the second
rule. It is then considered as a match and the device dials the number 101.
