Shared Call Appearance
Description
Shared Call Appearance, or SCA for short, is a feature that allows a user to be
associated with several devices in a fashion similar to the Concurrent Registrations
service. Unlike Concurrent Registrations, however, SCA extensions have the following
functions available:
• Monitoring the extension status via MPK/VPKs
• Restricting simultaneous calls from associated devices
• Barging into and picking up existing calls from an associated device.
Getting Started
Shared Call Appearance is available by default on the UCM starting from firmware
1.0.17.16. To use it:
1. Navigate to Extension/Trunk
→
Extensions
→
Edit Extension
→
Basic Settings
and tick the Enable SCA checkbox.
2. Navigate to Call Features
→
SCA
→
SCA Number Group and add a private
number to the desired extension. This private number will be used to
register devices to be associated with the main extension. To register to a
private number, the endpoint must have the following fields configured as
such:
a. SIP User ID : private number
b. Auth ID: main extension’s Auth ID. If no Auth ID is configured, the
main extension’s number will be used instead.
c. Password : main extension’s SIP password
3. (Optional) If an SCA extension and its associated private numbers want to
be able to barg
e into each other’s calls, Allow Bridging between Locations
in the Call Features
→
SCA page must be enabled.
Using the Service
Assuming the following:
• A and B are SIP extensions registered to the UCM.
• A1 is a SIP endpoint registered to an SCA private number associated with
A.
