Bridged Extensions (NBX Business Telephones only) With a bridged extension, buttons and status lights on one telephone are associated with buttons and status lights on another telephone, and you can perform the same operations (such as dialing telephone calls, placing calls on hold, forwarding calls, and so on) from either telephone.

Example:

■If an assistant answers a manager’s telephone calls, your administrator can map the manager’s extension on the assistant’s telephone.The manager’s telephone is the primary telephone, and the assistant’s telephone is the secondary telephone. Both telephones must be NBX Business Telephones.

A primary telephone’s extension can be mapped to one or more secondary telephones.
