Extensions

Bridged extensions allow you to have the extension of a primary

telephone appear on one or more secondary telephones. Most activities associated with the extension can be performed on both the primary telephone and any of the secondary telephones. However, you cannot use a bridged extension on a secondary telephone to place a call. On any NBX system, you can configure a maximum number of primary telephones and a maximum number of bridged extension on primary telephones. See Table 24.

Creating and Managing Bridged Extensions 139

There are no restrictions on the number of secondary telephones or the number of bridged extensions on secondary telephones.

Provided that you do not exceed the limits shown in Table 24, you can configure the maximum number of bridged extensions using any

combination of primary telephones and bridged extensions. For example, on a SuperStack 3 NBX system, you can configure 400 primary

telephones with three bridged extensions each or 300 primary telephones with 4 bridged extensions each to reach the limit of 1200.

You can configure a different number of bridged extension buttons on a primary and an associated secondary telephone. For example, if a primary telephone has 5 bridged extensions, one of the secondary telephones can be configured to have fewer (1 through 4) bridged extensions. However, if all of the primary bridged extensions are in use, the person at the secondary telephone will not be able to see all of the calls.

You can define any one telephone as either a primary telephone or a secondary telephone, but not both. If the telephone has an Attendant Console associated with it, the bridged extension functions for the telephone extend to the Attendant Console. For example, an NBX 2101 Basic Telephone with an associated Attendant Console, can be

configured as a primary telephone with up to 11 bridged extensions on Attendant Console buttons.

You can configure bridged extensions on the same buttons that are used for the telephone’s extension or on non-extension buttons. Before you can create a bridged extension on a telephone, you must unlock the button settings in the telephone group button mappings dialog box for the telephone group to which the telephone belongs.

You can view a report that lists the primary and secondary telephones on which bridged extensions have been defined. See “Viewing

Bridged Extension Information” on page 145.

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 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

Creating and Managing Bridged Extensions 141

which extension 1077 is to appear. On the 1088 telephone, buttons 10, 11, and 12 are configured as bridged extension buttons. On the 1099 telephone, buttons 3, 4, 5, 6, and 7 are configured as bridged extension appearances for extension 1077.

If a call is made to extension 1077, it can be answered using any of the following buttons:

■ Extension 1077 (primary telephone) — button 4 ■ Extension 1088 (secondary telephone) — button 10 ■ Extension 1099 (secondary telephone) — button 3

Secondary telephone 1099 has only two extension appearances for the 1099 extension because button 3, by default an extension appearance for the local telephone, has been used as a bridged appearance of extension 1077.

The primary telephone has buttons 1, 2, and 3 as local appearances of its own extension (1077). If multiple calls arrive at this telephone, they appear on buttons 4, 5, 6, 7, and 8, followed by 1, 2, 3.

Buttons 1, 2, and 3 on the 1077 telephone are not defined as bridged extension appearances. Therefore, they do not appear on either of the secondary telephones. If the owner of the 1077 telephone makes a call using any of these buttons, there is no indication (status light) of the call on either secondary telephone. If there are five active calls on the 1077 telephone, and a sixth call is made to that extension, it rings only on the 1077 telephone, on the first unused button in the 1, 2, 3 group).

Defining Bridged Extensions

The process of defining bridged extensions involves:

■ Defining Bridged Extensions on a Primary Telephone ■ Defining Bridged Extensions on a Secondary Telephone

Defining Bridged Extensions on a Primary Telephone

On a primary telephone, you can define from 1 to 11 buttons as bridged extensions. The buttons do not have to be next to each other.

To define the bridged extensions for the primary telephone: 1 Select NBX NetSet > Device Configuration > Telephones. 2 Select the primary telephone from the scroll list.

3 Click Button Mappings. The Telephone Button Mappings dialog box (Figure 19) appears.

4 For each button that you want to include in the group of bridged extension buttons:

a Select Bridged Extension from the drop-down list in the Type column. b Type the extension number of the primary telephone in the Number

column.

Figure 19 shows a group of three buttons that have been configured as bridged extension appearances for the extension (1066) on the primary telephone.

5 Click OK. Defining Bridged

Extensions on a Secondary Telephone

After you have defined the bridged extension buttons on the primary telephone, you can define the corresponding bridged extension buttons on a secondary telephone. You can do this for as many secondary telephones as you want.

To define the bridged extensions for a secondary telephone: 1 Select NBX NetSet > Device Configuration > Telephones. 2 Select the secondary telephone from the scroll list.

Figure 20 shows a group of three buttons that have been configured as bridged extension appearances for the extension (1066) associated with the primary telephone.

5 Click OK. Modifying Bridged

Extensions

You can modify bridged extensions on a primary telephone at any time. Bridged extensions do not need to be on adjacent buttons on a primary or a secondary telephone. You can have a different number of bridged extensions on a primary and a secondary telephone.

Sample Calling Situations Using Bridged Extensions

This section describes typical telephone call situations involving bridged extensions on primary and secondary telephones. For all of the examples:

■ The primary telephone is an NBX Business telephone (extension 1027)

used by a manager (Alicia). This telephone has buttons 2, 3, and 4 defined as bridged extension buttons. Button 1 is the manager’s private line.

■ One secondary telephone, an NBX Business Telephone (extension

1051), is used by the manager’s assistant (Bradley). On this telephone, buttons 1, 2, and 3 are extension appearances for extension 1051 and buttons 4, 5, and 6 are configured as bridged extension appearances of the manager’s telephone (1027).

■ The other secondary telephone is also an NBX Business Telephone

(extension 1018). The telephone is used by the person (Connie) who answers the manager’s telephone whenever the manager’s assistant is not available. Buttons 10, 11, and 12 are configured as bridged extension appearances of the manager’s telephone (1027).

Example 1: If there are no active calls on Alicia’s telephone, a call made to her telephone from either an internal or outside telephone rings on button 2 on her telephone, button 4 on Bradley’s telephone and button 10 on Connie’s telephone.

Bradley answers the call by pressing button 4. After identifying the person who is calling, Bradley places the call on hold and informs Alicia of the call. Alicia presses button 2 on her telephone to take the call.

During the time that Bradley is talking to the caller, neither Alicia nor Connie can access the call. Alicia can pick up the call only after it is placed on hold by Bradley. Similarly, after Alicia picks up the call, neither Bradley nor Connie can access the call. If Alicia wants to include either Bradley or Connie in the call, she can set up a conference call.

Example 2: Alicia wants to place a call but wants to keep all three bridged extensions available for incoming calls. Alicia can place the call using button 1.

Neither Bradley’s telephone nor Connie’s telephone shows any indication that there is a call on Alicia’s telephone, because button 1 on Alicia’s telephone is not configured as a bridged extension.

Example 3: Three incoming calls have arrived on Alicia’s telephone (on buttons 2, 3, and 4). Alicia is talking on button 2, Bradley has placed the second call on hold, and is talking to the third caller.

Creating and Managing Bridged Extensions 145

A fourth call arrives at Alicia’s extension and rings on button 1. Neither Bradley nor Connie can answer this call because that button on Alicia’s telephone is not a bridged extension appearance.

If a fifth call arrives at Alicia’s extension before the fourth call stops ringing, it is sent directly to Alicia’s voice mailbox, because all buttons are being used.

Example 4: A call arrives at Alicia’s telephone and the building has been evacuated because of a fire. Neither Alicia, nor Bradley, nor Connie is available to answer the call. After the number of rings that are configured for Alicia’s telephone, the call is sent to Alicia’s voice mailbox.

Example 5: A call arrives at Alicia’s telephone and Bradley answers the call, then places it on hold, and Alicia picks up the call. Bradley leaves the area, asking Connie to answer his telephone and Alicia’s until he returns. Alicia places the call on hold in order to pass the call back to Bradley but finds that he is not available. Connie is not close enough to Alicia’s office to permit Alicia to talk directly to her, so Alicia presses another button on her telephone, calls Connie’s extension, and asks her to pick up the call. Viewing

Bridged Extension Information

You can view a list of all telephones on the NBX system and determine which are primary telephones and which are secondary telephones. To view the bridged extensions information, select NBX NetSet > Device Configuration > Telephones> Bridged Extensions. The NBX Bridged Extensions Report appears.

If a telephone is a primary telephone, the Bridged Exts column contains the extension of the telephone and the extension of each associated secondary telephone. The Mapped Buttons column displays the

telephone’s extension once for each button that is mapped as a bridged extension.

Example: If extension 1002 is a primary telephone and extensions 1005, 1008, and 1019 are secondary telephones with 1002 mapped to them, the Bridged Exts column contains four extension numbers (1002, 1005, 1008, and 1019). If 3 buttons on the 1002 telephone are mapped as bridged extensions, the Mapped Buttons column contains extensions 1002, listed 3 times.
