1277 Call Detail Recording 
20
nTransfer
If a user originates a call on an outgoing trunk and then transfers the call to 
another extension, the originating extension is recorded as the calling party.
If a  user receives a call on an incoming trunk and then transfers the call to 
another extension, the extension that originally received the call is recorded 
as the dialed number.
If a  user receives an intraswitch call and then transfers it to another 
extension, the extension that originally received the call is recorded as the 
dialed number.
If call splitting is active, when a user receives or originates a trunk call and 
then transfers the call to another extension, two records are generated.
Intraswitch CDR records are generated for each call to or from an 
intraswitch optioned extension. For example, Station A, which is 
intraswitch optioned, calls Station B. Station A then transfers the call to 
Station C. When either Station B or C drops, two CDR records with 
Condition Code 0 are output: one for the A to B call, and the second for the 
A to C call.
Intraswitch CDR transfer records are output when both the calling number 
(originator) and dialed number (terminator) drop from the call. The 
duration of the call is from the time the terminator answers until both the 
originator and terminator have dropped from the call.
If ITCS is enabled and an incoming trunk call is transferred to a local 
extension that is optioned for Intraswitch CDR, the call produces an 
incoming trunk call record. It does not produce an Intraswitch record.
Users cannot dial an account code when transferring a call to another 
extension, unless they have console permissions. However, a user 
transferring a call to a trunk can dial an account code before dialing the 
ARS or TAC.
nTrunk-to-Trunk Transfer
Although they are not really conference calls, Trunk-to-Trunk Transfer 
connections are treated as such for CDR purposes. A separate CDR record 
is generated for each trunk in the connection.
Unanswered Trunk Calls may or may not be recorded depending on 
administration. You can administer each trunk group so that unanswered 
calls are recorded if they remain unanswered for a specified period of time.
If Incoming Trunk Call Splitting is active, a trunk-to-trunk transfer 
produces a record of the incoming call, and a record of the outgoing call. 
The outgoing call record shows the duration from the time the call was

transferred until both parties drop. The incoming call record shows the 
duration from the time the station receives the incoming trunk call until 
both parties drop.
nUniform Dial Plan
If one user calls another user via a UDP extension number, and the trunk 
group used has CDR assigned, CDR records the following information:
— Condition Code — 7
— Access Code Dialed — blank
— Access Code Used — trunk access code of trunk used
— Dialed Digits — Uniform Dial Plan extension
nVDN Return Destination
An incoming call does not generate a CDR record until the originator drops 
from the call. CDR creates a record when a call goes to the return 
destination VDN, the originator has not dropped, and vector processing — 
that is, the return destination VDN — routes the call to an outgoing trunk. 
CDR does not create a record if vector processing routes a call from the 
return destination VDN to an internal call. The call record shows only the 
first VDN that the caller accessed, no matter how many other extensions 
are involved in the call.
If an incoming VDN call is routed to a station, CDR includes the station in 
the record. If an incoming VDN call is routed to an outgoing trunk, CDR 
includes the VDN in the record.
Call Forwarding
Call Forwarding allows users to redirect calls to designated destinations. The 
forwarded-to destination can be an internal extension, external (off-net) number, 
an attendant group, or a specific attendant.
Call Forwarding provides five functions:
nCall Forwarding-All Calls — Allows a user to redirect every incoming call 
to the forwarded-to destination.
nCall Forward Busy/Don’t Answer — Allows a user to redirect incoming 
calls to a forwarded-to destination only when the user is busy or when the 
call is not answered after an administrable interval. If the extension is busy, 
the call forwards immediately. If the extension is not busy, the incoming 
call rings the called extension, then forwards only if it remains unanswered 
longer than the administered interval.

1279 Call Forwarding

nCall Forwarding Off Net— Allows a user to forward calls to an off-net 
destination.
nWhen the Coverage of Calls Redirected Off-Net field is activated, calls can 
be monitored for call progress tones, and if a call is not answered, it returns 
to the DEFINITY ECS for call coverage processing in some circumstances.
nCall Forwarding Override — Allows the user at the forwarded-to extension 
to override Call Forwarding at the forwarded-from extension on a per-call 
basis so the user can initiate a call or transfer a call back to the 
forwarded-from extension.
Detailed description
You assign Call Forwarding All Calls and Call Forwarding Busy/Don’t Answer to 
extensions on a Class of Service basis. You assign Call Forwarding Override and 
Call Forwarding Off-Net on a system-wide basis. You can also restrict Call 
Forwarding Off-Net with the Class of Service.
Call Forwarding All Calls
Phone users and data-terminal users can activate or deactivate Call Forwarding All 
Calls for their own terminals with a feature-access code or Call Forward-All 
feature button. An attendant or phone user with console permission can activate or 
deactivate the feature for another extension, TEG, DDC, UCD group, or ACD 
split (but not vector-controlled splits).
Call Forwarding Busy/Don’t Answer
The feature is activated or deactivated with a feature-access code or Call Forward 
Busy/Dont Answer feature button. An attendant or phone with console 
permission can also activate or deactivate the feature for another extension by 
using a feature-access code.
Call Forward Busy/Dont Answer cannot be activated for hunt groups, data 
extensions, or terminating extension groups (TEG). Calls to an attendant or EAS 
agent cannot be forwarded.
Call Forwarding Off Net
When a call is forwarded off net, the forwarded-to number can have up to 16 
digits. When counting the 16-digit limit, count the digits in the Trunk Access 
Code or AAR/ARS feature access code. Do not count the “#” used to terminate a 
forwarded-to number if the “#” is used.

If the Coverage of Calls Redirected Off-Net field on the System Parameters 
Customer-Options screen and the Coverage of Calls Redirected Off-Net Enabled 
field on the System Parameters - Call Coverage/Call Forwarding screen are both 
set to 
y, the system allows calls forwarded off-net to be monitored for busy or 
no-answer conditions. The system may bring the call back for call-coverage 
processing if the principal’s coverage criteria are satisfied at the forwarded-to 
destination. However, if the principal does not have a coverage path, the system 
does not monitor the call. It is left at the off-net destination regardless of whether 
it is answered or busy.
Calls forwarding off net require an available outgoing trunk. Additionally, when 
the Coverage of Calls Redirected Off-Net field is 
y, a call-classifier port may be 
required. If there are no call-classifier ports available when needed, the call still 
routes off net, but it is not monitored for call progress tones and cannot be 
returned to the switch for further call coverage processing.
Whenever an incoming trunk call is redirected off-net, a timer is set that precludes 
any other incoming trunk call from redirecting off-net until the timer either 
expires or is cancelled. The rationale for this mechanism is to prevent calls that 
were redirected off-net from being re-routed back to the original principal from 
the off-net destination, effectively creating a round-robin loop that continuously 
seizes trunks until they are exhausted. The blocked call receives busy tone or 
redirects to coverage.
NOTE:
If you send calls off-net and use the Call Classifier - Detector or the 
Tone-Clock (with Call Classifier-Tone Detector) circuit pack (the 
international version) for call classification and do not use the American 
tone plan, use the System-Parameters Country-Options screen to define 
specific country tones. If you use the Call Classifier - Detector or the 
Tone-Clock (with Call Classifier-Tone Detector) circuit pack (the 
international version) and do not use the System-Parameters 
Country-Options screen, your system will download the American tone plan 
regardless of your geographical location.
Call Forwarding — Override
You can administer Call Forwarding Override on a system-wide basis to allow a 
forwarded-to party to override Call Forwarding when placing a call to the 
forwarded-from party. Call Forwarding Override is invoked automatically if the 
system-wide override option is set.
Call Forwarding Override cannot be used when calls forward to an external 
number. Call Forwarding All Calls from a data user or a hunt group cannot be 
overridden with Call Forwarding Override.

Warning users if their calls are redirected
You can warn analog phone users if they have features active that may redirect 
calls. For example, if the user has activated call forwarding, you can administer a 
setting to play a special dial tone when the user goes off-hook. See ‘‘
Special Dial 
Tone’’ on page 656 for more information. 
Security
Use the 
list call-forwarding command to get general information and to identify 
unauthorized Call Forwarding feature activation. The list shows the station name, 
station number, and forwarded-to destination number.
!SECURITY ALERT:
Users who do not have permission to call out of the building may not do so 
with Call Forwarding. 
Considerations
Calls can be forwarded only once. Consider the following scenario. Extension A 
forwards its calls to extension B. Extension B forwards its calls to extension C. 
Calls made to extension A:
nRing at A, if possible
nRing at B, if possible
nRedirect to extension A’s coverage path, if available and A’s coverage 
criteria are satisfied when applied at B
nAre not forwarded to extension C
There is no maximum number of calls that can be forwarded simultaneously.
You can administer a phone to receive a redirection notification signal when a call 
is forwarded.
The system restricts users from forwarding calls to a number that they are not 
allowed to call.
If 
save translation is run after call forwarding is activated for a phone, 
forwarding status and destination number are saved to tape.

Attendant
Calls to attendants cannot be forwarded. However, calls can be forwarded to the 
attendant group.
The attendant cannot have a Call Forwarding button.
Only the attendant or phone user with console permission can activate Call 
Forwarding All Calls for Terminating Extension Groups (TEG), Uniform Call 
Distribution (UCD) groups, Direct Department Calling (DDC), and data modules.
Number of rings provided to a forwarded call
The following table shows the field used to specify the number of rings provided a 
forwarded call before the call redirects to coverage.
nCoverage path —- On the Coverage Path screen, the Number of Rings 
field.
nLocal — On the System-Parameters Coverage/Forwarding screen, the 
Local Subsequent Redirection/CFWD Don’t Answer Interval field.
nOff-net — On the System-Parameters Coverage/Forwarding screen, the 
Offnet Subsequent Redirection/CFWD Don’t Answer Interval field.
n* — No coverage treatment applied (rings until answered).
Example
If you forward all calls to a local site, the switch checks the Number of Rings field 
on the ‘‘
Coverage Path’’ screen.
If you forward busy/don’t answer calls to a local site, the switch checks the Local 
Subsequent Redirection/CFWD Don’t Answer Interval field on the ‘‘
System 
Parameters Call Coverage / Call Forwarding’’ screen.

Interactions
nAnswer Detection
This feature shares call-classifier resources with the Coverage of Calls 
Redirected Off-Net feature.
nAttendant Override of Diversion Features
If an attendant uses redirection override to call a user who has Call 
Forwarding active, the call does not forward and remains at the user’s 
phone.
nAutomatic Callback and Ringback Queuing
Automatic Callback cannot be activated toward a phone that has Call 
Forwarding active. If Automatic Callback was activated first, the callback 
call attempt is redirected to the forwarded-to party.
nBridging
Calls do not terminate to bridged appearances when Call Forward 
Busy/Don’t Answer is active.
The switch blocks users from bridging onto a call that has routed off net 
while the call is undergoing call classification.
nCall Coverage
If the principal’s (forwarding extension) redirection criteria are met at the 
designated (forwarded-to) destination, the forwarded call redirects to the 
principal’s coverage path; the designated destination gets a temporary 
bridged appearance (except when it is off net), which remains active after 
the call is answered so that the designated extension can bridge onto the 
call if desired. The temporary bridge appearance remains until the caller 
hangs up.
If Cover All Calls is part of the coverage redirection criteria and if Call 
Forwarding or Call Forwarding Off-Net is active at a phone, incoming 
priority calls forward to the designated destination; all other calls redirect 
according to the Call Coverage path. Non-priority calls are not directed off 
net.
When a covering user has activated Call Forwarding, a coverage redirected 
call does not forward to the designated extension number. Instead, the call 
is redirected to the next point in the principal’s coverage path, if available. 
If no other coverage point is available, the call remains at the principal’s 
phone.

nCall Detail Recording
When a call is forwarded to an off-net number, the call is recorded in CDR 
records as a call from the forwarding station. When the Coverage of Calls 
Redirected Off-Net field is 
y, a CDR record is generated only after the call 
has actually been answered off net.
If forced entry of account codes is required, calls cannot be forwarded to 
off-net destinations.
nCall Forwarding All Calls and Call Forward Busy/Don’t Answer
Call Forwarding All Calls and Call Forward Busy/Dont Answer cannot be 
active for the same phone at the same time.
nCall Park
Calls can be parked on a forwarded-from extension even though Call 
Forwarding is active for that extension. If a forwarded-to extension user 
parks a call that had been forwarded to that extension, the call is normally 
parked on the forwarded-to extension, not the forwarded-from extension.
nCall Pickup/Directed Call Pickup
If the Temporary Bridged Appearance on Call Pickup field is set to 
y on the 
Feature-Related System Parameters screen, a Temporary Bridged 
Appearance is maintained if the forwarded-to destination is a member of 
the same call pickup group as that of the forwarded from station. If the 
Temporary Bridged Appearance on Call Pickup field is set to 
n, a 
Temporary Bridged Appearance is not maintained.
nCall Prompting
This feature shares call-classifier resources with the Coverage of Calls 
Redirected Off-Net feature.
nCall Visor ASAI
This feature shares call-classifier resources with the Coverage of Calls 
Redirected Off-Net feature.
nConference
The switch blocks users from conferencing another party onto a call which 
has routed off net while the call is undergoing call classification. If any 
party on a call that has forwarded off net is on hold (due to the initiation of 
a conference), the call routes off net without undergoing call classification. 
This occurs even when the Coverage of Calls Redirected Off-Net field is 
y.

nExpert Agent Selection
Agents logged in with EAS enabled cannot activate or deactivate Call 
Forwarding. The physical extension where the EAS agent is logged in can 
be forwarded, but the EAS agent must first log out. Then, the phone can be 
forwarded.
nHold
If any party is on hold when a forwarded-to call routes off net, that call 
does not undergo call classification, even when the Coverage of Calls 
Redirected Off-Net field is 
y.
nIntercom—Automatic
When a phone with Intercom—Automatic is call forwarded to another 
phone, the auto-icom feature also forwards. Intercom—Automatic is not 
forwarded if a call forwards off-net.
nInterflow
The Interflow feature allows ACD calls to be redirected from one split to a 
split on another switch or to another external location. This is 
accomplished by forwarding calls that are directed to the split extension to 
an off-notify-net location via the Call Forwarding All Calls feature.
nIntraflow
Call forwarding can be used to unconditionally redirect ACD calls from a 
split to another destination on the same switch.
nLeave Word Calling
LWC cannot be activated toward a phone that has Call Forwarding 
activated. If LWC was activated before the called phone user activated Call 
Forwarding, the callback call attempt is redirected to the forwarded-to 
party.
nMFC Signaling
This feature shares call classification resources with the Coverage of Calls 
Redirected Off-Net feature.
nPersonal Central Office Line
PCOL calls cannot be forwarded.
nQSIG
If a call is forwarded over an ISDN-PRI trunk administered with 
supplementary service protocol “b” (QSIG), then additional call 
information may be displayed.

nSend All Calls
If an extension has both Send All Calls and Call Forwarding All Calls 
activated, calls to that extension that can immediately be redirected to 
coverage are redirected. However, other calls, such as Priority Calls, are 
forwarded to the designated extension.
Activation of Send All Calls at the forwarded-to extension does not affect 
calls forwarded to that extension.
nTemporary Bridged Appearance
The system maintains a Temporary Bridged Appearance for on-net calls 
after the call is answered or until the caller hangs up. However, for calls 
forwarded off-net, the system cannot maintain a Temporary Bridged 
Appearance. Once the call is redirected to the principal’s coverage path, the 
trunk to the off-net, forwarded-to, number is released.
nTraffic Reports Removed
The list measurement tone-receiver
 traffic reports provide port usage for 
this feature.
nTransfer
The switch blocks a user from transferring a call which has routed off net to 
another party while the call is undergoing call classification. If any party on 
a call that has routed off net is on hold (due to the initiation of a transfer), 
the call routes off net without undergoing call classification. This occurs 
even when the Coverage of Calls Redirected Off-Net field is 
y.
