User's Manual

• Telephones with a Privacy Override Allowed (POA) Class of Service can bridge into an
established call on an SCA MADN. However, you cannot bridge into a call until the call
establishes.
• Any user with the MADN SCA feature can put a call on hold. Any other user in the group
can pick up the held call by accessing the line key with SCA provisioned.
• The state of the user’s group is reflected in the line key icon. Three states are available;
idle, active, and held. For more information about line key icons, see the applicable IP
Deskphone User Guide.

Multiple Call Arrangement
Multiple Call Arrangement (MCA) MADN allows as in-progress calls as there are appearances
of the DN:
• A call on a DN appearance does not make other appearances busy (they can receive or
make calls).
• Activity on one DN appearance does not reflect on other appearances.
• There is no simple method for a DN appearance to bridge into or pick up a call on another
DN appearance.
