Creating and Managing Bridged Extensions 137
When you define bridged extension appearances on a primary telephone:
■Incoming calls appear on the bridged extension buttons first, followed
by the buttons (if any) associated with the primary telephone’s
extension. For example, by default, buttons 1, 2, and 3 are extension
appearances of the primary telephone. If you define buttons 4, 5, 6,
and 7 as bridged extensions on the primary telephone, incoming calls
appear on primary telephone buttons in the order 4, 5, 6, 7, 1, 2, 3.
■Any bridged extension appearance that overlaps one of the defined
extension appearances for the primary telephone (by default, buttons
1, 2, and 3 on an NBX Business Telephone) take precedence over
those extension appearances. For example, if you define buttons 3, 4,
5, 6, and 7 as bridged extension appearances on the primary
telephone, incoming calls appear on primary telephone buttons in the
order 3, 4, 5, 6, 7, 1, 2.
Example
Bridged Extensions
Configurations
Example 1: An NBX Business Telephone, extension 1044, is defined as a
primary telephone and buttons 2, 3, and 4 are defined as bridged
extension buttons. Two other NBX Business Telephones, extensions 1055
and 1066, are defined as secondary telephones on which extension 1044
appears. On the 1055 telephone, buttons 10, 11, and 12 are configured
as the three bridged extension buttons for the 1044 telephone. On the
1066 telephone, buttons 4, 5, and 6 are configured as bridged extension
appearances.
If a call is made to extension 1044, it can be answered using any of the
following buttons:
■Extension 1044 (primary telephone) — button 2
■Extension 1055 (secondary telephone) — button 10
■Extension 1066 (secondary telephone) — button 4
In this example, both secondary telephones use buttons 1, 2, and 3 as
extensions appearances for their own extensions.
Example 2: An NBX Business Telephone with extension 1077 is defined
as a primary telephone and buttons 4, 5, 6, 7, and 8 are defined as
bridged extension buttons. Two other NBX Business Telephones
(extensions 1088 and 1099) are defined as secondary telephones on
