IP phones at the same time. The shared line is indicated by a different line icon.

In the following figure, the first line is private and the second line is shared:

If two phones share a line, an incoming call to this extension will cause both phones to

ring simultaneously. The incoming call can be answered on either phone but not both.

This feature is very useful in the boss and secretary scenario. For example, the secretary

can share the boss's extension on her phone. When there is an incoming call to the

extension of the boss, both the phones of the boss and the secretary will ring

simultaneously. Either the boss or the secretary can answer the call. Calls on the shared

line can be placed on hold, barged in or retrieved from another shared phone.

You can configure a primary account on the IP phone and other alternate accounts on

the other IP phones. In a SCA Hybrid Key System scenario, you can automatically assign

multiple DSS keys with Line type for a registered shared line on the phone (If auto

linekeys feature is enabled). For example, party A, party B share the account 4603,

phone A registers the primary account 4603 and assigns line key 1 and line key 2 for the

account 4603, phone B registers the alternate account 4603_1 and assigns line key 1 and

line key 2 for the account 4603_1, phone C registers the account 4604.

To configure the auto linekeys feature via web user interface:

1. Click on Features-> General Information.

2. Select Enabled from the pull-down list of Auto LineKeys.

If Auto LineKeys is enabled, you can automatically assign multiple DSS keys with
