Shared Call Appearance Configuration
The Shared Call Appearance (SCA) feature allows the administrator to add multiple
locations to a given line. Any of the locations can be used to originate or receive calls.
When a call comes in to an idle line, all the provisioned locations for that line are alerted.
The first location to answer the call is connected to the originator. If the line is already
active in a call, only the active location is alerted.
A subscriber can originate calls from any of the configured locations. All other locations
are unable to originate calls until all calls are released.
It is recommended that the phone number plus an index (<phoneNumber>_<index>) is
used when provisioning the unique address of record (AoR) for each shared line. For
example: 2405551111_2. If a phone number does not exist, the MAC address plus an
index could be used (<macAddress>_<index>).
