nIf 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).
nThe Bridged Call Appearance feature should not be considered as a 
replacement for Call Coverage or any other similar features.
nIf 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
nThe 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.
nUp to six parties can be off-hook and involved in a conversation on a 
bridged appearance of an extension.
nA 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.
nBridged 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).
nIf 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).
nBridged Call Appearance should not be considered a replacement for Call 
Coverage.
nYou can administer conference tone, which, when enabled, is heard when 
two parties are bridged together on an active call with a third party.

Interactions
nAbbreviated Dialing
A user, accessing Abbreviated Dialing while on a bridged call appearance, 
accesses their own Abbreviated Dialing lists. The user does not access the 
Abbreviated Dialing lists of the primary extension associated with the 
bridged call appearance. 
A user cannot use an abbreviated dialing FAC after using a priority calling 
FA C .
nAdjunct Switch Applications Interface (ASAI)
If you are using ASAI, do not administer more than 16 bridged 
appearances.
nAttendant Display and telephone Display
A call from the primary extension number or from a bridged call 
appearance of the primary extension number is displayed as a call from the 
primary extension number (the call is displayed as coming from the 
primary extension number regardless of which appearance placed the call).
On multiappearance telephones, the display at a principal shows the same 
information for a bridged call appearance as it does for a nonbridged call. 
For calls to the principal’s extension number, the display at a zero call 
appearance bridging telephone shows a call from the originator to the 
principal with no “redirection reason” character. As telephones bridge onto 
the call, the display updates to show the number of parties in the 
conference.
nAutomatic Call Distribution
Bridged appearances cannot be accessed via non-ACD hunt groups 
(although administrable).
nAutomatic Callback
Automatic Callback calls cannot originate from a bridged call appearance. 
However, when Automatic Callback is activated from the principal user’s 
telephone, the callback call rings (with priority call distinctive ringing 
signal) at all bridged appearances of the extension as well as at the 
principal user’s telephone. Displays at all telephones (principal and bridged 
users) show that it is a callback call.

nCall Coverage
— Single-line telephones
When an analog telephone is administered as a bridged call 
appearance, the telephone user cannot invoke Send All Calls for the 
extension of their telephone. The user does not have a send all calls 
button, and the call appearance is associated with another extension. 
When the user dials a feature-access code (FAC), Send All Calls is 
activated for the extension associated with the call appearance.
— Multiappearance telephones
Coverage criteria for bridged call appearances is based entirely on 
the criteria of the primary extension associated with bridged 
appearance. A call to the primary extension that requires call 
coverage treatment follows the coverage path of the primary 
extension and not the path of any of the bridged appearances. 
Bridged call appearances do not receive redirection notification.
A user with bridged call appearances can activate or deactivate Send 
All Calls for a principal’s primary call appearance if they are on the 
bridged appearance.
The primary telephone should not be a member of a call coverage 
group, because calls to the primary telephone as a member of the 
group are not bridged.
You can administer the system so that a call can appear at a 
telephone as both a bridged call and a redirected call. In this way, if 
the bridged user is the first coverage point, the call redirects to that 
telephone when the coverage criteria are met.
If the principal is an analog telephone with a bridged call appearance 
on a multiappearance telephone, an incoming call to the analog 
telephone that goes to coverage terminates at a primary call 
appearance on the bridging user’s telephone as a coverage call. If 
the bridging user is a zero primary call appearance telephone, the 
call cannot redirect to the bridging user since there are no primary 
call appearances. Therefore, the call redirects to the next available 
coverage point.
nCall Detail Recording
If a bridging user originates or answers a call on a bridged appearance, the 
extension of the bridge is recorded as the calling/called telephone. A 
conference or transfer by a bridging user also appears as though it was 
performed by the telephone user.

1190 Bridged Call Appearance 
20
On multiappearance telephones, when a call originated from a bridged call 
appearance on a telephone administered for zero primary call appearance is 
recorded by Call Detail Recording (CDR), the extension number associated 
with the appearance is recorded as the calling party. A conference or 
transfer by a bridged call appearance on a zero primary call appearances 
telephone also appears as though it were performed by the extension 
associated with the appearance.
nCall Forwarding All Calls, Call Forward Busy/Don’t Answer
Call Forwarding can be activated or canceled for the primary extension 
number from any bridged call appearance of that number. When activated, 
calls to the primary extension number do not terminate at the bridged call 
appearances, but go to the designated forwarding destination. Bridged call 
appearances do not receive redirection notification of the call to the 
primary extension when it is forwarded unless Ringing — Abbreviated and 
Delayed is administered.
nCall Park
When a call is parked from a bridged call appearance, it is parked on the 
primary extension number.
nCall Pickup
— Single-line telephones
Calls to the primary telephone, alerting at bridged appearances of 
the primary telephone, can be picked up by member’s of the 
bridging user’s call pickup group. This causes all bridged 
appearances of the call to be dropped.
Calls ringing at a primary telephone can be picked up by members 
of the primary telephone’s call pickup group. However, if the 
primary telephone and the bridging user’s telephone are not in the 
same call pickup group, the bridging user cannot pick up calls to 
other members of the primary telephone’s call pickup group.
Originating on a bridged appearance and dialing the call pickup 
FAC is interpreted as an attempt to pick up a call from the primary 
telephone’s call pickup group.
A bridging user can use Call Pickup to pick up a call that is alerting 
at a bridged appearance, instead of selecting the bridged appearance 
button. This causes the call at the primary telephone and all bridged 
appearances of the call to be dropped.
If the bridging user has appearances of numerous single-line 
(primary) telephones (for example, sales, service, and warehouse), 
and it is not desired that the calls be answered by anyone other than 
the primary telephone user or the bridging users, the bridging user(s) 
should not be assigned to a pick up group.

1191 Bridged Call Appearance 
20
— Multiappearance telephones
If a telephone receives ringing on a bridged call appearance, the 
incoming call can be picked up by members of that telephone’s call 
pickup group. This causes all bridged call appearances to be 
dropped. Calls ringing at a primary telephone can be picked up by 
members of the telephone’s call pickup group. However, if the 
primary telephone and the bridging user’s primary telephone are not 
in the same call pickup group, the bridging user cannot pick up calls 
to other members of the primary telephone’s call pickup group.
Originating on a bridged appearance and dialing the call pickup 
Feature Access Code (FAC) is interpreted as an attempt to pick up a 
call from the primary telephone’s call pickup group.
A bridging user can use Call Pickup to pick up a call that is alerting 
at a bridged appearance, instead of selecting the bridged appearance 
button. This causes the call to terminate on the bridging user’s 
primary extension button, and the primary telephone and all bridged 
appearances of the call are dropped.
If the bridging user has appearances of numerous telephones (for 
example, sales, service, and warehouse), and it is not desired that the 
calls be answered by anyone other than the telephone user or the 
bridging users, the bridging users should not be assigned to a pick 
up group.
A telephone with zero primary call appearances can be assigned to a 
call pickup group.
nCall Waiting Termination (single-line telephones only)
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 can bridge onto a call with 
the primary user if there is also a call waiting.
nClass of Restriction (multiappearance telephone users only)
The COR assigned to a telephone’s primary extension also applies to calls 
originated from a bridged call appearance.
nConference — Attendant, Conference
— Single-line telephones
A bridged call cannot be conferenced if more than one user is active 
on that call. This is because the bridging user has no access to the 
call after the primary telephone user places the call on soft hold, and 
the primary telephone user has no access to the bridging user’s call 
appearance used for conference/transfer attempts.

1192 Bridged 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.

You can administer the system to automatically select the first idle 
appearance if there is no idle appearance with an extension matching 
the extension that is conferencing the call.
When the user presses the conference button (the second time) to 
connect the parties together, the newly formed conference call 
appears on the primary or bridged appearance to which the user was 
connected at the time of that last conference button depression. The 
other appearance is disassociated from the conference call. 
Therefore, if the original call is on a bridged appearance, and the 
conference is formed on an appearance of the bridged user’s own 
primary extension, the bridged extension becomes disassociated 
from the conference call and the principal user of that bridged 
extension can no longer bridge onto the conference.
This disassociation of the conference from the bridged extension can 
be avoided by setting up the conference in the opposite order. To do 
this, the user:
1. Presses the hold button to hold the original call on the 
bridged appearance
2. Selects a call appearance and calls the party to be added
3. Presses the conference or transfer button
4. Selects the held bridged appearance
5. Presses the conference button (again)
When this procedure is used, the conference is formed on the 
bridged appearance so that the primary user of the bridged extension 
can still bridge onto the conference call.
If the primary user and the bridged user are both on the call when 
one user transfers the call, the user performing the transfer becomes 
the controlling user for the participation of both users on the 
conference. To disassociate the appearance from the call, the 
controlling user must be the latter of the two users to hang up from 
the call. If the controlling user hangs up first, the appearance goes on 
soft hold when the noncontrolling party hangs up. In this case, one 
of two things must occur to disassociate the appearance from the 
call: all other parties on the call hang up, or the controlling user 
rejoins the call and hangs up again.
The display shows the number of other active parties in a call, 
including active bridged appearances.
nConsult (multiappearance telephones only)
Bridged call appearances of the primary extension do not ring on a consult 
call to the primary extension.

nCoverage Answer Group
— Single-line telephones
The primary (analog) telephone is not a member of a call coverage 
answer group, because calls to the primary telephone as a member 
of the group are not bridged.
If the primary telephone is made a member of a coverage group, 
coverage criteria is based entirely on the criteria of the primary 
telephone. This means that a call to the primary telephone that 
requires call coverage treatment follows the path of the primary 
telephone and not the path of any of the telephones with bridged 
appearances of the primary telephones. In this case, it is desirable to 
have the bridging user in the coverage path of the primary 
telephone. Then, when a call to the primary telephone requires 
coverage treatment, it follows the coverage path to the bridging 
user’s telephone, call appearances of the call are dropped, and the 
call terminates at the bridging user’s telephone as a coverage call.
— Multiappearance telephones
Bridged call appearances of a primary extension do not ring when 
there is a Coverage Answer Group (CAG) call to the primary 
extension. Bridged call appearances cannot bridge onto the call.
nData Privacy, Data Restriction
When Data Privacy is activated or Data Restriction is assigned to a 
telephone involved in a bridged call and the primary telephone and/or 
bridging user attempts to bridge onto the call, Data Privacy and Data 
Restriction are automatically overridden (or deactivated in the case of Data 
Privacy).
nBusy Indicator (multiappearance telephones only)
The call is placed to the resource from the first available bridged call 
appearance for zero primary call appearance telephones.

nHold — Automatic
— Single-line telephones
A call cannot be put on hold if more than one user is active on that 
call.
The primary telephone user, when no other bridges are active on the 
call, can put the call on hold, using normal single-line hold 
procedures. If the primary telephone user successfully soft holds the 
call, the status lamp at all of the bridged appearances shows the hold 
indication; and then the call can be put on hard hold by dialing the 
hard hold FAC. The hard held call is no longer accessible to the 
bridging users until it is taken off hold by the primary telephone 
user. After the call is put on hard hold, any new call to the primary 
telephone is tracked by the bridged appearances.
A bridging user can place an active call on hold (if the primary 
telephone or any other bridges are not active on the call) by using 
normal multiappearance hold procedures. Any attempt to enter the 
held call returns it to the status of an active call that can then be 
accessed using bridging procedures.
If hold is not allowed because of the preceding reasons, the user can 
just go on-hook and then reenter the call as required, because the 
call remains accessible as long as the primary telephone or any 
bridging user is active on it.
— Multiappearance telephones
Any user (primary or bridged appearance) can place an active call 
on hold. If only one user is active on a call and places that call on 
hold, the indicator lamp at both the principal’s appearance button 
and the bridged party’s appearance button shows that the call is on 
hold. If more than one user is bridged onto the active call, and one of 
the users activates Hold, the activator receives “hold” indication for 
the call and status lamp of all other bridged users remains active.
nHotline Service (single-line telephones)
If a single-line telephone is administered for Hotline Service, bridged 
appearances of that telephone’s extension also places a hot line call 
automatically when a user goes off-hook on that bridged appearance.
nHunt Group (DDC or UCD)
Bridged call appearances cannot be used in conjunction with DDC or UCD 
hunt groups.
Although you can assign a bridged extension to a hunt group, such 
assignment is not recommended because DDC/UCD calls do not terminate 
at any bridged appearances of that extension on other telephones.

nIntercom — Automatic and Intercom — Dial (multiappearance telephones 
only)
Bridged appearances of a primary extension number are not rung for 
intercom calls. Furthermore, if a telephone has no primary call appearances 
it can never be rung for an intercom call. Therefore, if a secretary is 
screening all calls for the principal, and is indicating who is calling via 
intercom, the principal must have a call appearance on which to receive 
and send intercom calls.
nInternal Automatic Answer
Calls terminating to a bridged appearance of an IAA-eligible telephone are 
not eligible for IAA.
nLast Number Dialed
Activation of the LND feature causes the last number dialed from the 
activating telephone to be redialed, regardless of the extension number 
used (primary or bridged call appearance).
nLeave Word Calling
A LWC message left by a user on a bridged call appearance leaves a 
message for the called party to call the primary extension number assigned 
to the bridged call appearance.
When a user calls a primary extension, and activates LWC, the message is 
left for the primary extension, even if the call was answered at a bridged 
call appearance.
LWC messages left by the primary user can be canceled by a bridged 
appearance user (for example, a secretary can cancel a LWC message left 
by a boss).
nPersonal Central Office Line
— Single-line telephones
A single-line primary telephone cannot be a member of a Personal 
Central Office Line (PCOL) group.
— Multiappearance telephones
If a user is active on his or her primary extension number on a 
PCOL call, bridged call appearances of that extension number 
cannot be used to bridge onto the call. The call can only be bridged 
onto the call if another telephone is a member of the same PCOL 
group and has a PCOL button.
nPreference
Ringing Line Preference selects an alerting bridged appearance; Idle Line 
Preference does not.
