| DTMF | None entered | Nothing is sent, calling party number is blank |
Call Forwarding Feature
Used to enable/disable the Call Forward feature at the Signaling Group level. The Call Forward feature allows a phone connected to an FXS port to forward calls to another telephone number. Available options: Enabled or Disabled. Once this field is enabled, the Call Forwarding Activate DTMF and Call Forwarding Deactivate DTMF fields become visible. To enable at the channel level, you must activate at the Assigned Channel Table, Assigned Channels - Field Definitions, or activate through the physical phone, How to Operate Call Forward on Telephone. Once Call Forward is activated and a keycode is configured, you must configure a route on the SBC to route the forwarded number. If a route is not provided, the call will fail.
Call Forwarding Availability
Call forwarding is supported for Analog FXS only.
Field Behavior
The Call Forwarding Feature field is only visible when Analog is selected in the Line Type field. If the Line Type has been set to Analog and Call Forwarding has been enabled then Line Type is subsequently set to Digital:
- Call Forwarding is automatically disabled.
- The Call Forwarding Feature field is hidden.
The Call Forwarding feature enables a phone connected to an FXS port to forward incoming calls to another configured telephone number. The SBC supports unconditional call forward on an individual port basis. Call Forward is activated/deactivated on a port with configured specific service codes, accompanied by the forward number. Once the user enters the configured keycode and forward telephone number, all outgoing calls to the port will then be redirected to the forwarding number. When the outgoing call routes to a port that is forwarded, the phone on that port generates a short ring.
In North America, the NANP defines *72<forward number> for activation and *73 for deactivation, but the SBC enables you to configure any 6 character combination for activation and/or deactivation. The SBC enables a keycode to have a minimum length of 3 characters and a maximum of 6; this is based on what is commonly used today.
Call Forwarding Feature
Activate through a Telephone
The Call Forward feature can be initiated with the following steps:
- Lift the handset to the port (in which calls will be forwarded) and enter the activate keycode + forwarded number, followed by the '#' key on the telephone.
- A confirmation tone (fast beep) indicates a successful Call Forward. A congestion tone (busy tone) indicates call forward failed.
- An activation at the physical phone level automatically activates the feature for the applicable channel in the Assigned Channels table. See Assigned Channels - Field Definitions.
Deactivate through a Telephone
- Lift the handset connected to the port in which calls are being forwarded (that requires deactivation) and enter the deactivate keycode.
- A confirmation tone (fast beep) indicates a successful Call Forward deactivation. A congestion tone (busy tone) indicates call forward has not been deactivated.
Activate on a Channel through the Channel Table
The Call Forward feature can be activated for a specific channel through the Assigned Channels table as follows:
In order for the feature to be available at the channel level, ensure the Call Forwarding feature is enabled under CAS Protocol. See #Call Forwarding Feature.

No Channel Available Override
In the event of a "No Channel/Circuit available" release cause code, the specified cause code will be sent to the relevant protocol module. For more information see the list of Cause Codes.
NOTE: This attribute relates only to Inbound calls on the Signaling Group where applied.
Call Setup Response Timer
Specifies the interval of time, in milliseconds, after an call is initiated that the Ribbon SBC 1000/2000 waits for a call to connect before terminating the incoming call.
Assigned Channels - Field Definitions
Channels are assigned to specific Signaling Groups (SG). The channels for a digital SG can be made up of all or part of channels from one or more digital ports in the system. Likewise, "channels" for 1 analog SG can be made up of any analog ports in the system. When you click on the 
icon, the Create Assigned Channels window is displayed. Field definitions are below.
For a CAS Signaling Group using E&M/Loop Start signaling (T1/Analog) or CAS R2 (E1), a maximum of 48 channels can be assigned to the signaling group.
For E1, limit channels to 30 (to not go over the maximum 48 channels). Otherwise, the following will occur:
- The span (48 channels) is split across two signaling groups.
- When the limit of 48 channels in the span is met, 18 channels from one of the signaling groups must be deleted before a new signaling group can be created.
DS1 Port Selection
Specifies the DS1 port from which channels will be assigned to this SG. This field is only visible when the Line Type is specified as Digital.
Channel Selection Method
Specifies the method by which to assign ports to analog cards or channels to digital ports. Available options: Digital (All Channels, Single Channel, or Range of Channels), Analog (All Ports on a Card or Single Port).
Analog Card Selection
Specifies the analog card to which ports will be assigned. This field is only visible when the #Line Type is specified as Analog.
Channel Phone Number
Specifies a specific phone number to assign to a channel.
