1181Bridged Call Appearance
20
If a bridging user is active on a bridged call and the primary analog
telephone user attempts a conference, the attempt is ignored. The
same is true if an analog bridging user attempts a conference when
the primary telephone user and another bridging user is active on a
call.
When the primary telephone user is active on a call, and no other
bridging user is active on the call, that call can be placed on hold by
the primary telephone user utilizing normal single-line conference
procedures. Any attempt by a bridging user to bridge onto the call
during a successful conference attempt is denied.
A bridging user, alone on a bridged call, can conference the call
utilizing the normal multiappearance telephone conference
procedures. Any attempt by the analog primary telephone user to
bridge onto the call during a successful conference attempt is
ignored. Any attempt by other bridging users is denied (standard
denial response is returned to the bridged appearance).
If a conference is not allowed because of the preceding limitations,
the user can accomplish a transfer by asking an internal nonbridged
party in the connection to create the conference, or asking the
remaining bridging users and primary user to disconnect so that the
conference can be completed. At completion of the conference, the
parties that left the call can reenter the call if control of the
conference remains with the primary telephone. If control of the
conference does not remain with the primary telephone, the bridging
user must conference the primary telephone and the bridging user
back into the call as required.
If the bridging user has no other available bridged appearances of
the primary extension (other than the one he or she is currently on),
the bridging user, after pressing the conference/transfer button, must
select a call appearance to be used for the conference, before dialing
the number.
— Multiappearance telephones
Call Waiting Termination applies only to an active call on the
primary telephone that has no one else bridged on. If one or more
bridging users are active on a call, Call Waiting calls are denied
whether or not the primary user is also off-hook on the call. A
bridging user cannot bridge onto a call with the primary user if there
is also a call waiting.
Conferences can be set up on bridged appearances using the usual
conference operations. Either a primary extension button or a
bridged appearance button can be used to make the calls for adding
to the conference.
