Advanced Shared Line Feature Key

Advanced Shared Line, also known as Shared Line Appearance, is a device feature key that enables a group of up to 35 IP phones to share and monitor the same target line. Any user in the group can use the shared line on their own device to:

• Answer an inbound call
• Place an outbound call
• Place a call on hold
• Resume a held call

The line status is updated across all shared devices in real time. Incoming calls ring on all devices, and any user can answer. When the shared line is busy, it appears as busy on all devices, and no one else in the group can make or receive a call on that line. Additionally, if the target device line loses registration, incoming calls will still ring to the line on the shared devices.

One device can be assigned as many Advanced Shared Line references as needed, making it an especially useful feature for administrative assistants or receptionists who regularly handle calls for other users.

Advanced Shared Line is not yet available for Cisco devices.

Configure Device Feature Key

1. In the Admin Portal, go to either:
   • Account > Business Cloud > Devices
   • Account > Business Cloud > Users > Devices
2. Locate the device you want to add the shared line to and click Edit.
3. Under Line Configuration, edit the line on your device you want to assign the feature to.
4. In the Device Line Info modal, configure the following:
   • Type: Advanced Shared Line
   • Target user: Select the user whose device line will be referenced on this device.
   • Device: Select a device assigned to the target user.
   • Line: Select an active line on the target user's device.
     • Line 1 on the target user's device is listed as "Line."
     • The line on the target user's device must be configured as a Device Line. See Device Line Configuration for details.
     • A single device line can be referenced on up to 35 devices. If the line you’re looking for isn’t listed, it may be maxed out.
   • Advanced shared line display name: Enter a name for the line that will be displayed on this device, such as the name of the monitored user.
5. Click [Save]. The feature key is assigned to the device.

Key System Emulation

Alianza’s Advanced Shared Line feature can be used to emulate a key system in which all phones have the same lines instead of extensions.

On all devices, Line 1 is reserved for the device itself and cannot be assigned a feature. However, it can be referenced on another device as an Advanced Shared Line. The name displayed on the device for Line 1 is the username on their account; however, the name can be customized on each shared device when configuring the Advanced Shared Line.

In the example below, we have three phones, each of which has a shared line for the other two, and Line 4 is a shared parking spot which is owned by the first phone.
