OR E&M DESTINATION 
NOTE: There may be some reduction in voice volume 
when an outside call is transferred to an outside tele- 
phone number depending on the quality of the trunks be- 
inguscd. 
16.9 When a trunk is being used by either outside 
party, the duration of an outside call that is transferred to 
outside telephone numbers is limited by the Unsuper- 
vised CO timer. When this timer expires, the outside 
parties hear a burst of dial tone. They may then press any 
MMP key (before the SL Set Dial Initiation timer ex- 
pires) to reset the timer. Ifthe timer is not reset, the unsu- 
pervised call recalls the primary attendant. If the 
attendant does not answer the recall before the Aban- 
doned Call timer expires, the call is disconnected by the 
system. 
NOTE: While this system is designed to be reasonably 
secure against CO trunk misuse by outside callers, there 
is no implied warranty that it is invulnerable to unautho- 
rized intrusions. Ifthe central office does not provide su- 
pervision and disconnect the call when one party hangs 
up, it is possible for a caller to remain connected to a CO 
trunk circuit. If this happens, and the caller begins dial- 
ing, the call could be placed through the 416/832 System 
and would then be billed to the system’s owner. The sys- 
tem cannot check this type of call for toll restriction and 
may not register the call in SMDR. This problem could 
arise when a call is connected to a station, when a call is 
in an unsupervised conference, when a call is forwarded 
or transferred to the public network, or when DISA is 
used for placing outgoing calls.

ter the Reverse Transfer feature code (4) and dial a hunt 
group’s pilot number to pick up a call that is ringing in to 
the hunt group’s pilot number or to any station within 
that hunt group. 
17.6 The system follows the priority list shown below 
to determine which call is picked up. The system fol- 
lows the hunt group list (always beginuing with the first 
station on the list) to check each station in the hunt group 
and then the overflow station for one type of call at a 
time. If there is more than one call of the same type at the 
selected station, the call that was received by the station 
first is picked up. Camped-on calls, holding calls, and 
queue callbacks cannot be picked up.

18. CALL PRIVACY AND PRIVACY 
RELEASE 
18.1 Call Privacy restricts voice channel access to one 
station at a time. When a voice channel is selected, no 
other station user can gain access to the channel. How- 
ever, access to and control of a channel can be passed to 
another station using the Conference or Transfer fea- 
tures. 
18.2 In addition, the database contains an installer- 
programmable option that can be set to enable Call Pri- 
vacy on all trunks or to allow keyset users to join an 
ongoing call by pressing the lit individual trunk key (see 
PROGRAMMING, page 5-54). Single-line set users 
cannot join calls, but keyset users can join a call that in- 
volves a single-line station. When the system is in the 
default state, calls on all trunks are private and any user 
attempting to access a busy trunk will hear busy tones; 
18.3 When the Privacy Release feature is enabled, any 
keyset user may join an ongoing outside call by lifting 
the handset (or pressing the SPKR key) and pressing the 
lit individual trunk key (cannot use a call key or trunk 
group key). Exceptions to this are established confer- 
ence calls, data calls, calls on individual hold, DISA 
calls, and calls forced private by the user. If desired, as 
many as seven stations can participate in one call. When 
a station user hangs up, only that user is disconnected; 
all other parties remain connected. (Par an explanation 
of feature restrictions on multi-party calls, refer to the 
conferencing section on page 4-76.) To queue or camp 
on to a busy individual trunk (rather than join the con- versation), a station user must remain on hook and press 
the busy individual trunk key. 
18.4 Even when Privacy Release is enabled system- 
wide, an individual station user can restore call privacy 
during an outside call by entering the private call feature 
code or by placing the station in do-not-disturb. (Note 
that the station must be placed in do-not-disturb during 
the call to enable privacy; if do-not-disturb is enabled 
beJore the call, privacy is not enabled.) The call then 
cannot be joined by other people unless the conferenc- 
ing feature is used. If the call is transferred or placed on 
system hold, the privacy restore feature is cancelled. 
Privacy is retained if the call is put on individual hold. 
18.5 There is a programmable option that enables or 
disables a signal tone (barge confirmation tone) that is 
heard by the parties on the call whenever another user 
joins the call. 
18.6 
To RESKME PRIKACYONA NON-PRlWlE l?RUNE 
Keyset: While on an outside call, press the SPCL 
key and enter the Private CO Call feature code 
(369), or place the station in do-not-disturb by 
pressing the DND key or pressing SPCL and 
entering a Do-Not-Disturb feature code (370 or 
372). 
Single-Line: While on an outside call, press the 
FLASH key (hookflash) and enter the Private 
CO Call feature code (369), or place the station 
in do-not-disturb by pressing the FXASH key 
and entering a Do-Not-Disturb feature code (370 
or 372).

Issue 1. November 1994 
19. BARGE (KEYSETS ONLY) 
19.1 Ifthe Barge feature is enabled system-wide, key- 
set stations can be programmed (on a station-by-station 
basis) to use the Barge feature. This permits the keyset 
user to join an ongoing call by entering the Barge feature 
code. Another option is available on a station-by-station 
basis that prevents other stations from barging into calls 
on the station. 
19.2 only keysets can use the Barge feature to join the 
conversation of any station (keyset or single-line set) to 
which the keyset user may make a call. The keyset user 
may never barge into a station that he or she could not 
otherwise call, such as a cross-tenant station when the 
system does not allow cross-tenant traffic. 
19.3 A hunt group supervisor may barge on any call 
that it can monitor; this could conceivably be a station 
that he or she could not otherwise call. 
19.4 Barge is not affected by do-not-disturb mode, the 
Call Privacy and Private Call features, or ring intercom 
always. If any of these are programmed on the receiving 
station, Barge will override them. 
19.5 A Barge call will be received through the second- 
ary voice path as an off-hook voice announce call if the 
station being called is an OHVA-enabled digital keyset, 
lMX 12/24-line keyset, or DVK keyset and the user is 
using the handset (using the speakerphone or a headset 
would block the secondary voice path). Although it uses 
the secondary voice path, Barge cm be used if OHVAis 
not enabled system-wide; the receiving keyset does not 
have to be programmed to receive OWA 
19.6 A Barge call will be received as a conference 
with the ongoing call if the secondary voice path is not 
available or the keyset user is on one of the following 
types of calls: 
0 An intercom call. 
0 A conference that does not exceed the maximum ca- 
pacity of parties. 
0 An outside call using the speakerphone or headset. 
19.7 A barge cannot be completed on data calls or 
calls on conference wait hold. Nor can a barge be com- 
pleted if the conference resources or voice channels are 
not available. 
19.8 When a keyset party joins a conference call, the 
parties in the ongoing call hear a single tone (barge con- 
firmation tone). The call then continues as a conference. 
19.9 
lDJOlN(EARGE)ANONW~GCALLFROMAK%YSiX: 
If the rreceiving station does not have an avail- 
able secondary voicepath: When placing an in- 
tercom call or while monitoring a call, if you 
hear busy signals press SPCL and enter the Barge 
feature code (397). The parties in the ongoing 
call hear a single tone and you are conferenced 
with all parties. 
If the receiving station has an available second- 
ary voice path: When you hear busy signals 
while placing an intercom call, press SPCL and 
enter the Barge feature code (397). You are con- 
nected to the keyset user through the secondary 
voice path (speakerphone) as if you were placing 
an off-hook voice announce call.

20. CONFERENCE CALLS 
20.1 Station users can establish a three- to eight-party 
conference without operator assistance. A station user 
can initiate one conference at a time and the system can 
maintain up to 32 parties in conference calls of up to 
eight parties each. In addition to the initiating station, 
the conference can include any combination of up to 
seven intercom and/or outside calls. The initiating sta- 
tion is considered one of the conferencing parties. 
20.2 If a conference is terminated using the Hold fea- 
ture, the remaining callers hear music while they are 
waiting. The station user must return to the callers one at 
a time. If the Hold timer expires, the calls on hold recall 
the station that placed them on hold in the order they 
were placed. If still unanswered after the Recall timer 
expires, they recall the station’s attendant. 
203 While a conference call is in progress, the inside 
parties camrot dial numbers, enter hookflashes, or use 
the Call Transfer features. Also, if any inside party exits 
the conference by pressing the CNP key, the remaining 
inside parties may not use the Conference Wait or Hold 
features to exit or terminate the conference. 
20.4 Unlike the call privacy release option (page 
4-74) where station users can join an ongoing call by 
lifting the handset and pressing a busy individual trunk 
key, conferences are private and station users attempt- 
ing to join an ongoing conference call by pressing a busy 
individual trunk key will hear busy tones, and may camp 
on to the trunk. 
NOTE: During a conference, some reduction in voice 
volume may be noticed, depending on CO trunk quality. 
A. PLACING A CO NJ?ERENCE CALL

C. EXITING A CONFERENCE 
20.7 There are several options for leaving the confer- 
ence: 
End the conference by hanging up. The other parties 
remain connected as long as one is a station (inside 
party). If there are no stations remaining, the confer- 
ence is disconnected. 
Place all parties on individual hold (refer to para- 
graph 20.8). The conference is terminated. You must 
return to the callers one at a time. To reestablish the 
conference, repeat the procedures in paragraph 20.5. 
NOTE: If a keyset user attempts to place a confer- 
ence call on system hold, all parties will be placed on 
individual hold. If a single-line set user attempts to 
place the conference call on system hold, the user 
hears reorder tones and the call continues. 
Leave the conference and allow the outside parties 
to remain connected (refer to paragraph 20.9). You 
can return to the conference at any time. 
NOTE: While this system is designed to be reasonably 
secure against CO trunk misuse by outside callers, there 
is no implied warranty that it is invulnerable to unautho- 
rized intrusions. Ifthe central office does not provide su- 
pervision and disconnect the call when one party hangs 
up, it is possible for a caller to remain connected to a CO 
trunk circuit. If this happens, and the caller begins dial- 
ing, the call could be placed through the 416/832 System 
and would then be billed to the system’s owner. The sys- 
tem cannot check this type of call for toll restriction and 
may not register the call in SMDR. This problem could 
arise when a call is connected to a station, when a call is 
in an unsupervised conference, when a call is forwarded 
or transferred to the public network, or when DISA is 
used for placing outgoing calls.

21. SYSTEM FORWARDING 
21.1 System Forwarding provides the ability to pro- 
gram the system so that calls ringing at a station will fol- 
low a database-programmed “forwarding path” that 
routes the call based on the type of call and the status of 
the intended station. (The station feature Call Forward- 
ing can also be used at stations with System Forward- 
ing.) Several terms will be used to describe this feature, 
including: 
Principal Station: Original station being called. 
Forwardii Point: A destination (station, voice 
mail port, or hunt group) to which the call is directed 
when the principal station is unavailable. Each for- 
warding path can contain up to four forwarding 
points. 
Forwarding Path: The sequence of forwarding 
points to which the call will be sent. Forwarding 
paths are programmed in the database. Up to 200 
unique paths can be programmed for a standard sys- 
tem (400 for an expanded system). Each station can 
have up to three forwarding paths. 
213 Two system timers are used with this feature: 
System Forwarding Initiate: This timer deter- 
mines how long a call will ring (unanswered) at the 
principal station before moving to the first forward- 
ing point. The default value is 15 seconds and the 
range is 2-255 seconds. 
System Forwarding Advance: When the forward- 
ing point is a station, this timer determines how long 
the call will ring (unanswered) before moving to the 
next forwarding point. The default value is 15 se- 
conds and the range is 2-255 seconds. (If the for- 
warding point is a hunt group, the hunt group 
Overflow timer is used.) 
21.3 For each forwarding path assigned to the station, 
the system checks the following three criteria to deter- 
mine if and when a call should be forwarded: 
l Type of incoming call: Any combination of the fol- 
lowing seven types of calls can be forwarded: 
- Ringing outside calls 
- Transferred outside calls 
- Recalling outside calls 
- DISA/automated attendant calls 
- DID calls 
- E&M calls 
- Intercom calls 
l Station status: The system recognizes four different 
types of station status. 
- No Answer: If the call is not answered at the 
principal station before the System Forwarding 
Initiate timer expires, the system advances the 
call to the forwarding path. 
- Busy: If the principal station is busy, the system 
immediately advances the call to the forwarding 
path. Both “No Answer” and “Busy” can be 
selected together to form a “Not Available” 
St&US. 
- Do Not Disturb: If the principal station is in 
do-not-disturb, the system immediately sends 
the call to the forwarding path. 
- Immediate: The system immediately sends the 
call to the forwarding path. The principal station 
user camrot answer the forwarded call, but can 
reverse transfer it. 
0 Day-mode/night-mode status of the station’s 
tenant group: 
The mode of a station’s tenant group 
is used to determine if a forwarding path is used. Ei- 
ther day mode, night mode, or both may be speci- 
fied. 
21.4 For example, during the day, the “principal” may 
want direct ring-in or transferred calls to ring at his sta- 
tion. If he does not answer them, the calls would follow 
the forwarding path to a forwarding point hunt group. If 
the hunt group does not answer his calls, the calls would 
continue on the forwarding path and go to his voice 
mailbox (another forwarding point). 
21.5 If the principal station is a keyset, the “ring prin- 
cipal once” option can be set that will signal the princi- 
pal station when a call begins to follow the forwarding 
path. The signal to the principal station consists of a dis- 
play @XXXXXX SENT To FWD PAllI) and a single 
burst of ring tone. The call cannot be answered at the 
principal station, but can be reverse transferred. 
21.6 If a call rings in to multiple stations, and one or 
more of those stations has system forwarding, the call 
will not follow any of the forwarding paths. 
21.7 If a principal station or a station forwarding point 
is a member of a hunt group, calls placed to the hunt 
group’s pilot number are unaffected by system fonvard- 
ing. The hunt group calls will be received at the station 
as usual and will not enter the system forwarding path.

Hands& Announce System Forward Option 
218 
When the a call is transferred to the principal 
station by another station user and the principal &a- 
tion’ssystemfonvprdLsetfort~“noa~e~ltfation 
sfatus, a system-wide option determines what the caller 
hears. If the “handsfree announce system forward” op- 
tion is enabled, the transferring station user will place a 
handsfree call to the principal station and can announce 
the transfer; the System Forwarding Initiate timer does 
not start until the transfer is completed. (An exception to 
this is if intercom calls are programmed to be sent to the 
forwarding path, in which case the handsfree announce 
option is overridden and the intercom call from the 
transferring station enters the forwarding path.) If the 
option is disabled, the intercom call from the transfer- 
ring station automatically enters the forwarding path; 
the station user hears ringing and can announce the call 
OXI@ if it is answered. Regardless of the option setting, if 
the transfer is sent to a hunt group forwarding point, the 
transfer will be completed automatically and the trans- 
ferring station user will hear intercom dial tone. If the 
transfer follows the system forward path to a voice mail 
station, the transfer is completed immediately and the 
principal station’s mailbox number is 
dialed. 
Individual Station Forwarding Points 
automatically 
21.9 The ringing duration at each station forwarding 
point is determined by the System Forwarding Advance 
timer (defaults to 15 seconds). Ifthe station forwarding 
point is busy, the call will camp-on until the SystemFor- 
warding Advance timer expires and then it moves to the 
next forwarding point. 
21.10 If the station forwarding point is in 
do-not-disturb, the forwarding path will bypass that sta- 
tion and immediately send the call to the next forward- 
ing point. 
21.11 A station forwarding point can place calls or 
transfer calls to the principal. 
Hunt Group Forwarding Points 
21.12 
If a forwarding point is a hunt group, a call fol- 
lowing the forwarding path will not be sent to the an- 
nouncement station or overflow station; it will advance 
to the next forwarding point if not answered before the 
hunt group Overflow timer expires. 
21.13 The ringing duration within hunt group for- 
warding points is determined by the No Answer Ad- 
vance timer. 
21.14 If all stations in a hunt group forwarding point 
have Do-Not-Disturb or Hunt Group Remove enabled, 
the call will camp on until the Ovefflow timer expires. 
The call will then be sent to the next forwarding point. 
The call will not be sent to the hunt group’s overflow or 
announcement station. 
Call Forwarding 
And System Forwardii 
21.15 
A call follows only the forwarding path of the 
principal, even if a forwarding point has call forward en- 
abled or has a forwarding path of its own. The call that 
originated at the principal station will follow only the 
principal station’s forwarding path. 
21.16 If the principal station has call forward enabled 
(using the FWD key or one of the Call Forwarding fea- 
ture codes), the call forward overrides System Fonvard- 
ing. 
21.17 If the principle station receives a manually for- 
warded call (not a system forward), that call will follow 
the principal station’s system forwarding path. 
21.18 lf an infinite forward loop results from the com- 
bination of forwards and system forwarding paths, the 
station that was originally intended to receive the call 
will ring, even if the station is in do-not-disturb.
