1176Bridged Call Appearance

■If a call terminates at a telephone on an extension number other than the

primary extension number (for example, terminating extension group

(TEG), uniform call distribution (UCD) group, call coverage answer group,

or direct department calling (DDC) group extension number), a bridged

call appearance is not maintained. Therefore, the primary telephone should

not be made a member of such a group (even though administration of this

is not prohibited).

■The Bridged Call Appearance feature should not be considered as a

replacement for Call Coverage or any other similar features.

■If two parties are bridged together on an active call with a third party, and if

the conference tone feature is enabled, conference tone is heard.

Considerations for multiappearance telephones

■The number of bridged call appearances allowed at each telephone is

limited only by the number of 2-lamp buttons available on the telephone.

The number of appearances per primary extension varies by system. See

DEFINITY ECS System Description for this information.

■Up to six parties can be off-hook and involved in a conversation on a

bridged appearance of an extension.

■A bridging telephone should have a bridged call appearance corresponding

to each call appearance of the primary extension number at the bridged

telephone. For example, if a primary telephone has three call appearances,

a bridging telephone should have three bridged call appearances of that

primary extension. This allows users to refer to the in dividual call

appearances when talking about a specific call.

■Bridged call appearances may result in the reduction of available feature

buttons, thereby reducing a user’s capabilities. A Call Coverage module or

expansion module can be used to provide up to 20 bridged call

appearances. This leaves the other 2-lamp buttons as call appearances, or

with other features such as Centralized Attendant Service (CAS).

■If a call terminates at a telephone on an extension number other than the

primary extension number (for example, TEG, UCD group, call coverage

answer group, or DDC group extension number), a bridged call appearance

is not maintained. Therefore, the primary telephone should not be made a

member of such a group (even though administration of this is not

prohibited).

■Bridged Call Appearance should not be considered a replacement for Call

Coverage.

■You can administer conference tone, which, when enabled, is heard when

two parties are bridged together on an active call with a third party.
