4.4 SIP Advanced Feature Configuration
This section provides configuration instructions for advanced SIP features supported by
the phone including but not limited to Shared Call Appearance, Busy Lamp Field, Feature
Key Synchronization, Call Center, Emergency Call, Advice of Charge, Call Recording, and
Security Classification.
4.4.1 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 to use the phone number plus an index (<phoneNumber>_<index>)
when provisioning the unique AoR for each shared line, for example: 2405551111_2. If a
phone number does not exist, use the Media Access Control (MAC) address plus an index
(<macAddress>_<index>).
