Bridged call appearance
Considerations for single-line telephones
•
The number of bridged call appearances allowed varies by system. See Hardware Guide for
Avaya Communication Manager for those numbers. A bridging user cannot have more than one
bridged appearance for a particular primary telephone. However, a multiappearance bridging user
can have appearances of more than one analog telephone on their telephone (a multiappearance
bridging user, by use of different buttons, can bridge onto several different primary telephones).
•
The number of bridged appearances allowed on a multiappearance bridging user's telephone is
limited only by the number of 2-lamp buttons available on the telephone.
•
If the primary single-line telephone is correctly administered, but not in service, calls can still be
placed by the bridging users, and received on the bridged appearances of the telephone. The
primary telephone can be out of service for several reasons, such as an unplugged telephone, a
nonexistent telephone system technician busyout command, etc.
•
If more than one user goes off-hook on a bridged appearance at the same time, only the user who
was the first to go off-hook can dial.
•
If a bridging user is not active on a call, and bridges onto the appearance of an active call, the user
is bridged onto the active call. If a multiappearance bridging user is active on a call, and bridges
onto the appearance of an active call, the previously selected call is dropped and the user is
bridged onto the active call.
•
The Privacy-Manual Exclusion feature can be activated by the bridging user only, while active on
a call, to prevent accidental bridging of an active call.
•
If a call terminates at a telephone on an extension number other than the primary extension
number (for example, terminating extension group (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).
•
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 Hardware Guide for Avaya Communication Manager 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 individual 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).
