1.14.4 Background Music (BGM)
Description
A proprietary telephone (PT) user can listen to background music (BGM) through the built-in speaker while 
on-hook and idle.
Conditions
Hardware requirement: A user-supplied external audio device, such as a CD player or radio for 
External audio source.
 The music heard through the PT is interrupted when going off-hook, receiving a call, or receiving a 
paging announcement.
 The audio can be selected through system programming ( Music on Hold [111]).
 This feature can be turned on and off by dialing 1 while the extension is on-hook and idle, if BGM is 
enabled through system programming (
 BGM Control for APT [626]).

1.14.5 Outgoing Message (OGM)
Description
An extension assigned as the operator or manager extension can record outgoing messages (OGMs) for 
the following features:
Conditions
Hardware Requirement: An optional Message Expansion card for OGM.
 This feature functions differently from personal/common OGMs used by the BV feature ( 1.14.7 Built-
in Voice Message (BV)).
 To use the OGM feature, DISA must be selected as the distribution method for the desired outside 
(CO) line port (
 CO Line Mode—Day/Night/Lunch [414-416]).
 The PBX can record a maximum of 32 messages (8 messages for DISA and 24 messages for 3-level 
AA). When an optional Message Expansion card for OGM is added, the total recording time of the PBX 
is increased to 6 minutes.
 After recording messages, the operator and manager can also play them back for confirmation. In 
addition, the operator and manager can erase messages for DISA.
 When the operator or manager tries to record or play back a message, he or she will hear an alarm 
tone if the message channel is in use. 
 Prerecorded messages will not be cleared by a system restart. To clear them, use system programming 
(
 Clear All OGMs of DISA [599]).

1.14.6 Direct Inward System Access (DISA)
Description
Direct Inward System Access (DISA) allows outside callers to be connected to their desired PBX 
destinations without the use of the operator. Callers can listen to an outgoing message (OGM) instructing 
them as to which numbers to dial to be connected to the person or department they would like to speak with. 
DISA can also give PBX users access to PBX features, such as making outside (CO) line calls, when they 
are outside the office.
This OGM can guide callers and allow them to:
 Call an extension by dialing the extension number.
 Call another outside party via the outside (CO) lines of the PBX.
 Access the desired extension simply by dialing a single-digit number (DISA Automated Attendant 
[AA] number) using DISA AA service.
OGM
When a call arrives on a DISA line, callers will hear an OGM or a short beep. When the DISA AA service is 
active, this OGM will direct callers to dial the appropriate digit (DISA AA number) to be connected to a 
specified destination. To access other PBX features, such as making intercom or outside (CO) line calls, the 
caller may dial the appropriate numbers while the OGM is playing. 
 
An extension assigned as the operator or manager extension can record an OGM ( 1.14.5 Outgoing 
Message (OGM)).
DISA AA Service
DISA AA service allows a caller to dial a single-digit number (DISA AA number) and be connected to the 
desired party automatically. The PBX can store up to 10 destinations that can be called by dialing a DISA 
AA number (0–9) for each OGM (
 DISA Built-in AA [501]). These destinations can be an extension 
number ( Extension Number [009]), an extension group number ( Extension Group [600]), or the DISA 
AA number of a 3-level OGM ( 3-level AA Assignment [540-549]).  
After or while listening to the OGM or a short beep, the caller may dial a DISA AA number as directed by 
the OGM (e.g., Press 1 to speak to Sales. Press 2 to speak to Support.). 
 
Each DISA AA number directs the call to a preprogrammed location.  
Since DISA AA numbers are single digits, if the caller dials a second digit within a preprogrammed time 
period (
 DISA AA Wait Time [517]), DISA AA service will be bypassed because the PBX will assume the 
caller is trying to access a specific feature. 
When the DISA AA service is used, Incoming Dial Mode must be set to With AA through system 
programming (
 DISA Incoming Call Dial Mode [500]). When With AA is selected, the PBX regards caller-
dialed digits 0 through 9 as DISA AA numbers. If no destination is assigned to 9 or 0, the PBX regards 
the number (9/0) as the Automatic Line Access number or Operator Call number.

[Programming Example: 3-level AA Table] 
In order for a caller to be able to access Mike Smith of the Software Support Team (extension 102) using 
the 3-level AA feature, program as follows:
In this example: 
1)After or while listening to the AA first-level OGM (e.g., Press 1 to speak to Sales. Press 2 to speak 
to Service. Press 3 to speak to Support.), caller dials a DISA AA number, 3, as directed by the 
OGM.
2)Next, the AA second-level OGM (e.g., Press 1 to speak to Hardware Team. Press 2 to speak to 
Software Team.) directs the caller to dial another DISA AA number. The caller dials 2. 
3)Last, the AA third-level OGM (e.g., Press 1 to speak to Mike Smith. Press 0 to speak to the 
Operator.) directs the caller to dial a DISA AA number, 1, to be connected to a specified 
destination, extension 102. 
Note
When the type of a destination from 2–level AA or 3–level AA to another setting is changed, any 
associated OGM will also be cleared. In addition, any items within the AA menu being removed will also 
be removed.

DISA Busy Mode
If the destination of a DISA call is busy, the call will be redirected to an idle extension ( Hunting Group Set 
[100]) in the destinations idle extension hunting group ( 1.2.1 Idle Extension Hunting). If no extension in 
the group is available, or if the destination of the DISA call is not a member of an idle extension hunting 
group, the call will be handled in one of the following ways, according to system programming (
 DISA Busy 
Mode [506]):
a)Disconnect: The caller hears a busy tone and the call is disconnected.
b)Call Waiting: The called extension hears a call waiting tone if the extension has set Call Waiting.
c)DISA: The following procedure is performed:
1)If the assigned OGM (busy message) has been recorded, the caller hears the OGM (e.g., The 
party you called is unavailable...). If the assigned OGM has not been recorded, the caller 
hears a busy tone and the call is disconnected.
2)After the busy message has been played, the OGM that was sent before the busy message is 
sent to the caller again.
3)The PBX waits for the caller to enter a new destination. In this case, the PBX does not accept 
any Outside Line Access number regardless of the security type.
If the destination is a member of a DISA ring group, DISA Busy Mode will not function for the call. The PBX 
regards it as unanswered.
DISA Intercept Mode
If the destination of a DISA call does not answer the call within a preprogrammed time period ( DISA Ring 
Time before Intercept [508]), the call will be handled in one of the following ways, according to system 
programming ( DISA Intercept Mode [507]):
a)Disconnect: The call is disconnected. 
b)Intercept: The call is redirected to preprogrammed intercept destinations in the following priority:  
DISA IRNA to BV—Day/Night/Lunch [438-440]  Flexible Ringing—Day/Night/Lunch [408-410]  
This is useful for business calls. For example, the call can be forwarded to the operator, a Voice 
Processing System (VPS) or Built-in Voice Message (BV) automatically.
DISA No Dial Mode
If the PBX does not receive either DTMF (Dual Tone Multi-Frequency) signals or a fax (CNG) tone within a 
preprogrammed time period (
 DISA Wait Time after OGM [505]), or if the PBX does not receive DTMF 
signals within a preprogrammed time period ( Intercept Time for Internal DISA [515]), the call will be 
handled in one of the following ways, according to system programming ( DISA No Dial Mode [510]): 
a)Disconnect: The call is disconnected.
b)Intercept: The call is redirected to preprogrammed intercept destinations in the following priority:  
DISA IRNA to BV—Day/Night/Lunch [438-440]  Flexible Ringing—Day/Night/Lunch [408-410]
DISA Security Mode
Security can be enabled for the PBX to control the types of calls that can be made by callers using DISA. 
When the DISA security mode is set to All Security or Trunk Security (
 DISA Security Mode [511]), a 
caller is required to enter a DISA security code ( DISA Security Code [512]) before making intercom and 
outside (CO) line calls, or outside (CO) line calls only, respectively. The DISA security code and the number 
of digits required for the DISA security code (
 DISA Security Code Digits [530]) can be assigned by the 
manager. After entering a DISA security code, if the code is the same as one of the preprogrammed security 
codes, the caller will hear a short beep. It is possible to eliminate the tone through system programming (
 
DISA Tone after Security Code [518]). 
If the DISA security code is entered incorrectly 3 times when using DISA, a reorder tone will be sent to the 
caller and the call will be disconnected.

 Permitted
Outside-to-Outside (CO-to-CO) Line Calls through DISA
DISA callers can use DISA to make outside (CO) line calls when allowed by the DISA security mode.  
If a call between 2 outside parties is established via DISA, the length of the call can be limited to a 
preprogrammed duration (
 CO-to-CO Line Call Duration [205]). A timer will activate when the call is 
connected, and a warning tone will be heard 15 seconds before the timer expires. When the timer expires, 
the call is disconnected (
 1.9.8 Outside-to-Outside (CO-to-CO) Line Call Duration).  
To detect the end of an outside-to-outside (CO-to-CO) line call, Calling Party Control (CPC) Signal Detection 
can be assigned through system programming (
 CPC Signal Detection—Incoming [420], CPC Signal 
Detection—Outgoing [421]).

Conditions
WARNING 
There is a risk that fraudulent telephone calls will be made using the Outside-to-Outside (CO-to-CO) 
Line Call feature of DISA.
 
The cost of such calls will be billed to the owner/renter of the PBX. 
To protect the PBX from this kind of fraudulent use, we strongly recommend:
a)Enabling DISA security (Trunk Security or All Security).
b)Maintaining the secrecy of passwords.
c)Selecting passwords that are complex and random, so that they cannot be easily guessed.
d)Changing passwords regularly. 
Hardware Requirement: An optional Message Expansion card for OGM.
 The maximum recording time of each message is 3 minutes.
 The preinstalled DISA card can play only one message at a time and the maximum recording time is 3 
minutes. When an optional Message Expansion card for OGM is added, up to 2 messages can be 
played simultaneously for callers and the total recording time of the PBX is increased to 6 minutes.
 To use this feature, DISA must be selected as the distribution method for the desired outside (CO) line 
port (
 CO Line Mode—Day/Night/Lunch [414-416]).
DISA Delayed Answer Time 
It is possible to set the DISA Delayed Answer time ( DISA Delayed Answer Time [504]) so that the 
caller will hear a ringback tone for a preprogrammed length of time before hearing an OGM or a short 
beep.
Call Forwarding (FWD) to Outside (CO) Line 
When a DISA call is forwarded to an outside party, the caller is not required to enter a DISA security 
code regardless of the security mode.
SMDR 
The following are logged by SMDR for DISA calls ( 1.19.1 Station Message Detail Recording 
(SMDR)):
– The destination of the DISA call
– DISA security code status 
Call Deny 
System programming determines which extensions can receive DISA calls ( DISA Incoming 
Assignment [516]). If a DISA call is received at an extension that has Call Deny set, the caller will hear 
a reorder tone and the call will be disconnected automatically. If a DISA call is received by a DISA ring 
group, this program does not function for extensions in that DISA ring group and these extensions will 
still ring.
Cyclic Tone Detection 
It is possible to select the number of times a cyclic tone must be detected while the DISA OGM is sent 
(
 Cyclic Tone Detection [513]). Cyclic Tone Detection can be used to disconnect an outside-to-
outside (CO-to-CO) line call via DISA.
Fax Connection 
System programming determines the extensions that are able to receive fax data when the PBX 
receives a fax (CNG) tone via the DISA feature (
 FAX Connection [503]). The preprogrammed 
extension will automatically have the Data Line Security feature set. It is possible to select the number 
of times the fax (CNG) tone must be detected while the DISA OGM is sent before the PBX recognizes 
the incoming signal as fax data (
 FAX Tone Detection [514]).
 It is programmable whether a ringback tone ( Ringback Tone Pattern [128]) or Music on Hold ( 
Music on Hold [111]) is sent to the caller when a DISA call is received ( DISA Ringback Tone [531]).

1.14.7 Built-in Voice Message (BV)
Description
If an optional voice message card is installed in the PBX, a caller can leave a voice message in one of the 
voice message areas, and information on the recorded messages is automatically logged in the Incoming 
Call Log of the extension, where it can be viewed later or used to play back the original message (
 1.15.2 
Incoming Call Log). 
There are 2 types of voice message area: personal message area and common message area. 
The personal message area for each extension stores the following: 
– Personal outgoing messages (OGMs)
– Voice messages left by callers 
Messages can be recorded, played, and erased by that extensions user.
The common message area stores the following: 
– Personal OGMs for the operator or manager
– Voice messages left by callers for the operator or manager
– Common OGMs for the company
– Voice messages left by callers for the company
Messages can be recorded, played, and erased by the operator or manager only.
If there are any voice messages in the voice message area that an extension user can access, the user will 
hear a special dial tone (dial tone 4) when going off-hook. In addition, if that users telephone has a Caller 
ID Indication—Personal/Common button, MESSAGE button or Message/Ringer Lamp, the corresponding 
button or lamp will light. A MESSAGE button can be used to listen to the message after the user goes off-
hook. Pressing the lit MESSAGE button on a display proprietary telephone (PT) while on-hook shows voice 
message information.
 
The Built-in Voice Message (BV) feature allows users to also perform the following operations:
 If an outside (CO) line call is preprogrammed to be automatically directed to a common BV ( CO 
Line Mode—Day/Night/Lunch [414-416]), or if a Direct Inward System Access (DISA) call is 
preprogrammed to be redirected to a common BV via Intercept Routing ( DISA IRNA to BV—
Day/Night/Lunch [438-440]), the caller will hear a common OGM and can leave a voice message 
directly in the common message area.
 An extension user can set incoming calls to be forwarded to his or her personal message area, 
when he or she cannot answer them. If an incoming call, direct to the users extension, or a call 
using the DISA AA service (
 CO Line Mode—Day/Night/Lunch [414-416]), is forwarded to the 
users personal message area, the caller will hear a personal OGM and can leave a voice 
message.
Direct Message feature 
An extension user can leave a voice message directly in the personal message area of another 
extension, even if the extension has not been set to forward incoming calls to its personal message 
area, or even if no OGM has been recorded. When a caller leaves a voice message using this 
feature, the voice message is automatically linked to the Caller ID information, recorded in the 
corresponding call log.
 An extension user can play and/or erase voice messages from the users extension. In addition, 
the user can remotely play and/or erase voice messages through an outside (CO) line. The user 
accesses the relevant voice message area by entering a preprogrammed voice message access 
code (
 BV Access Code through CO Line [625]) while hearing a personal/common OGM or DISA 
OGM. 
Note
If the Voice Mail Integration feature has been set, the BV feature will not function.
