Bridged call appearance
Issue 5 October 2002 1507555-233-506
Considerations for single-line telephones
■ The number of bridged call appearances allowed varies by system. See
Avaya MultiVantage™ Solutions Hardware Guide 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.
