Creating and Modifying Supplementary Service Profiles

Used to enable/disable the Hold/Off Hold feature.

When enabled, the user can perform a flash hook (quickly depressing button on the handset cradle) to put the active call on hold, after which they will hear a dial tone. To take the call off hold and resume speaking, the user performs a second flash hook. If the call remains on hold for more than 20 seconds, the dial tone changes to a fast busy tone. The user can perform a flash hook at anytime to resume the call.

Used to enable/disable the Transfer feature. If enabled, the user can perform a flash hook to get a dial tone (the active call will be put on hold) and to start dialing the phone number that the active call will be transferred to.

The Ribbon SBC 1000/2000 supports two transfer modes, attended and unattended, both work similarly by transferring a call from one receiving extension to another receiving extension.

An attended transfer is that transfer scenario in which the user at the new receiving extension answers the call before the user transferring the call (original recipient) hangs up. An unattended (or blind) transfer is that transfer scenario in which the user transferring call hangs up after the new recipient's extension begins to ring and before they answer.

Transfer Mode

Normal Transfer (attended or unattended)
To transfer a call, one of the parties (User B) on the call performs a flash hook (quickly depressing button on the handset cradle), dials the number of the user (User C) to which they want to transfer the call, and then hangs up.

No Answer
If the new recipient of the call fails to answer within a predetermined length of time, the ring back tone heard by the connected caller(s) with become a fast busy tone. If this is an attended transfer, both will hear the ring tone, then fast busy.

Rejected Transfer
Assume that User A is connected to User B, then User B transfers the call to User C. User C answers the call. If User C hangs up before User B the call reverts to a call between User A and User B.

Used to enable/disable the Call Waiting feature. If enabled, Call Waiting allows an FXS port to handle two calls at the same time. When Call Waiting is enabled on an FXS port, the user on the FXS port is notified of an incoming new call even though the user is already on an existing call. At the same time, the second caller hears ring back. Call waiting notification is in the form of a double-tone with configurable frequency and on/off intervals.

Available options: Enabled (the FXS port will receive call waiting notification when a second call destined for the same port comes into the port) or Disabled (any incoming call destined for the FXS port engaged in another call receives a busy signal). Default entry: Disabled.

Call Waiting - How does it work?

Call Waiting is triggered when a user at the FXS port is in a call and another call from another user gets routed to the same FXS port.

 

Call Waiting

When the user receives a call waiting notification (a double-tone), the following options are available: 

Conversation is placed on hold.
User can place the existing call on hold and answer the new call by hitting the flash button on the analog phone. The on-hold caller hears silence.

Existing conversation is ended.
User can end the existing conversation by simply hanging up the phone and answering the new call. The current call is disconnected and the phone rings to answer the second call.

Ignore the new call.
User can ignore the new call by continuing the conversation on the existing call. The SBC will stop the call waiting notification tone after three cycles.

New caller disconnects call.
The new caller can disconnect the call. As a result, the call waiting notification stops.

Far end of active call disconnects.
The far end of the active call disconnects. The user on the FXO port hears silence until the flash button is hit to answer the new call, or the user hangs up (in which case the phone will ring).

How to configure Call Waiting

The following configuration must be completed for Call Waiting:

• Enable Call Waiting through the CAS Supplementary Profile.
• Configure the Call Waiting tones through Creating and Modifying Tone Tables. The tone parameters must match the country where the SBC 1000/2000 is hosted. For more information about country-specific values for these tone parameters, see Various Tone Used in Nation Networks.
• Configure the FXS CAS Signaling Group (which uses the CAS Supplementary profile) as follows: From the Channel Hunting drop down box, select Own Number. See Creating and Modifying CAS Signaling Groups.
