Shared Lines
Shared Lines feature allows sharing of an extension across multiple phones to handle calls as a
group. The feature has two modes:
• Shared Call appearance mode (SCA) available for Broadsoft environment
• Bridged Lines appearance mode (BLA) available for Ring Central environment
All phones sharing this extension will support:
• Displaying incoming calls.
• Initiating outbound calls.
• Displaying the same caller ID for an outgoing call for all phones in the group.
• Displaying the state of all calls on the extension of all phones that share the extension.
• Joining calls on other phones in the group, if configured.
• Effective eliminating of any missed calls.
Note:
Avaya J129 IP Phone does not support Shared Lines.
Usage of SCA on the phone
Depending on the configuration, there are different approaches to how SCA can be used on the
phone. The common configuration methods are Key System and Attendant Console.
Key System
A Key System configuration emulates legacy systems where many phones are configured with the
same set of lines or extensions. For example, Key System might include four different extensions
where the primary extension is configured as shared. All users with the same configuration will
share the same extensions. Each configured extensions can be associated with a Direct Inward
Dialing(DID) line and the incoming calls roll over to the next line when a line is busy.
Attendant Console
An Attendant Console configuration supports one phone to monitor the calls on multiple other
phones. For example, the phone of an Executive Assistant can be configured with a shared
extension of an Executive so that the Executive Assistant can answer incoming calls for the
Executive or initiate outbound calls on behalf of the Executive. In this configuration, the Executive
Assistant will have a primary extension that is private and one SCA for each Executive that the
Executive Assistant supports. Each Executive will have only a primary extension which is shared.
SCA configuration
Extensions can be configured as Shared Call Appearance (SCA) on the Broadsoft server to be
used as SCA or a primary shared extension on the phone.
