Bridged Extensions With a bridged extension, buttons and status lights on one telephone are
associated with buttons and status lights on another telephone. On the
primary telephone, you can perform all operations (such as dialing
telephone calls, placing calls on hold, forwarding calls, and so on). On the
secondary telephone, you can answer calls that are made to the primary
telephone’s extension but you cannot make calls using the buttons that
are associated with the primary telephone.
