1.15 Optional Device Features

1.15.1 Doorphone Call

Description

A visitor can use a doorphone to call its preprogrammed destination. Extension users can call a doorphone. Doorphones can also be used for the Room Monitor feature ( 1.10.2 Room Monitor).

Conditions

•	Hardware Requirement: An optional doorphone, and doorphone card.
•	Doorphones 1 and 2 (or doorphones 3 and 4) cannot be used at the same time. When one is in use, the user cannot have a conversation with the other.
•	A doorphone access tone will be sent to a monitored doorphone before monitoring starts. If an extension user wants to monitor a doorphone without informing the other party, it is possible to eliminate the tone through system programming ( Doorphone Access Tone [707]).
•	Ring Duration If an incoming doorphone call is not answered within a preprogrammed time period ( Doorphone Ring Time [708]), ringing stops and the call is cancelled. An extension user can choose the preferred ring tone pattern for doorphone calls through system programming ( Doorphone Ring Tone Pattern [706]).
•	Call Destination System programming determines the extensions that can receive calls from each doorphone for each time service mode ( Doorphone Ringing—Day/Night/Lunch [700-702]).
•	Door Open While on a doorphone call, an extension user can unlock the door to let the visitor in ( 1.15.2 Door Open).
•	When a doorphone call is received at a proprietary telephone (PT), a tone is heard instead of ringing.

1.15.2 Door Open

Description

Using an extension telephone, an extension user can unlock a door for a visitor. The door can be unlocked by extension users who are allowed through system programming to unlock the door for each time service mode ( Door Opener—Day/Night/Lunch [703-705]). While on a doorphone call, any extension user can unlock a door to let a visitor in ( 1.15.1 Doorphone Call).

Conditions

•	Hardware Requirement: A user-supplied door opener installed on each door.
•	A door opener can unlock a door even if no doorphone is installed.
•	Door Open Duration An opened door will remain unlocked for a preprogrammed length of time ( Door Open Duration [709]).

1.15.3 Doorbell/Door Chime

Description

Extension users can choose how their telephones receive doorphone calls, by selecting to hear ringing, a chime, or both, provided a doorbell/door chime connected to a door opener is connected to the PBX. They can recognise which doorphone is ringing by selecting a different doorphone chime pattern for each doorphone.

[Programming Example] In order for an extension connected to extension jack 01 (extension 101) to be able to receive a doorphone call from a doorbell/door chime connected to Relay 4, programme as follows:

Programming Doorphone 1 2 3 4 Doorphone Ringing*1 Enable (extn. 101) Enable (extn. 101) Enable (extn. 101) Enable (extn. 101) Doorphone Ring/Chime*2 Chime Chime Chime Chime Doorphone Chime Assignment*3 Relay 4 Relay 4 Relay 4 Relay 4 Doorphone Chime Pattern*4 Pattern 1 Pattern 2 Pattern 3 Pattern 4

*1 Doorphone Ringing—Day/Night/Lunch [700-702] *2 Doorphone Ring/Chime [710] *3 Doorphone Chime Assignment [711] *4 Doorphone Chime Pattern [712]

In this example When a visitor presses the Call button of Doorphone 2:

– A doorbell/door chime, connected to Relay 4, chimes with Pattern 2. – Because Doorphone Ring/Chime is set to "Chime", extension 101 does not ring. – The extension user who is allowed to receive a call from Doorphone 2 can answer the doorphone call by going off-hook within a preprogrammed time period ( Doorphone Ring Time [708]). If the user is allowed to unlock the door ( Door Opener—Day/Night/Lunch [703-705]), he or she can then unlock the door by entering the Door Open feature number. – If the called extension is busy and has set Call Waiting, the extension user hears a call waiting tone and the call information flashes on the display.

1.15.4 Background Music (BGM)

Description

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 dialling "1" while the extension is on-hook and idle, if BGM is enabled through system programming ( BGM Control for APT [626]).

1.15.5 Outgoing Message (OGM) for DISA/UCD

Description

An extension assigned as the operator or manager extension can record outgoing messages (OGMs) for the following features:

Feature Usage Details in Direct Inward System Access (DISA) When a call arrives on a DISA line, the caller will hear a DISA OGM. • 1.15.6 Direct Inward System Access (DISA) 3-level Automated Attendant (AA)  When the DISA AA service is active, the caller will hear a DISA OGM. The DISA AA service supports up to 3 levels of DISA OGMs. • 1.15.6 Direct Inward System Access (DISA) Uniform Call Distribution (UCD) When a call arrives at a UCD group and all extensions in the group are busy, the caller will hear a UCD OGM ( UCD Waiting Message [527]). • 1.2.2 Uniform Call Distribution (UCD)

Conditions

•	This feature functions differently from personal/common BV OGMs used by the BV feature ( 1.15.7 Built-in Voice Message (BV)).
•	To use this feature, "DISA" or "UCD" must be selected as the distribution method for the desired outside (CO) line port ( CO Line Mode—Day/Night/Lunch [414-416]).
•	The operator or manager can record a maximum of 32 messages (8 messages for DISA/UCD and 24 messages for 3-level AA). When an optional message expansion card for DISA/UCD OGMs is added, up to 2 messages can be played simultaneously for callers, and the total recording time of the PBX is increased from 3 to 6 minutes.
•	After recording messages, the operator or manager can also play them back for confirmation. In addition, the operator or manager can erase messages for DISA/UCD.
•	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/UCD [599]).

1.15.6 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 a DISA 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 DISA OGM can guide callers and allow them to:

• Call an extension by dialling the extension number. • Call another outside party via the outside (CO) lines of the PBX. • Access the desired extension simply by dialling a single-digit number (DISA Automated Attendant [AA] number) using DISA AA service.

DISA OGM

When a call arrives on a DISA line, callers will hear a DISA OGM or a short beep. When the DISA AA service is active, this DISA 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 DISA OGM is playing. An extension assigned as the operator or manager extension can record a DISA OGM ( 1.15.5 Outgoing Message (OGM) for DISA/UCD).

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 dialling a DISA AA number (0–9) for each DISA 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 DISA OGM ( 3-level AA Assignment [540-549]). During or after the DISA OGM announcement ( DISA Wait Time after OGM [505]), or after a short beep ( Intercept Time for Internal DISA [515]), the caller may dial a DISA AA number as directed by the DISA 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-dialled 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 ( Automatic Line Access [121]) or Operator Call number.

Note * For New Zealand, the Automatic Line Access number may be either 1 or 9.

[Programming Example: 1-level (DISA) AA Table]

In order for a caller to be able to access Mike Smith (extension 102) using 1-level (DISA) AA, programme as follows:

Outside (CO) Line No. Distribution method*1 Day Lunch Night 1, 2 DISA OGM1 DISA OGM1 DISA OGM1 3–8 Normal Normal Normal

DISA AA No. for 1-level AA*2 0 1 2 3 4 5 6 7 8 9 – Mike Smith (102) Extn. 103 Extn. 104 Extn. 105 Extn. 106 Extn. 107 Extn. 108 Extn. Group 1 –

*1 CO Line Mode—Day/Night/Lunch [414-416] *2 DISA Built-in AA [501]

[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 3-level AA, programme as follows:

Outside (CO) Line No. Distribution method*1 Day Lunch Night 1–4 DISA OGM1 DISA OGM2 DISA OGM3 5–8 Normal Normal Normal

*1 CO Line Mode—Day/Night/Lunch [414-416] *2 DISA Built-in AA [501] *3 2-level AA: Select "3-level AA" for AA number "3" in DISA Built-in AA [501] *4 3-level AA Assignment [540-549] *5 3-level AA: Select "3-level AA" for "second AA number 2" and for "third AA number " in the [543] of 3-level AA Assignment [540-549] *6 Mike Smith (102): Select "Jack 02" for "second AA number 2" and for "third AA number 1" in the [543] of 3-level AA Assignment [540-549]

In this example:

1) After or while listening to the AA first-level DISA 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 DISA OGM. 2) Next, the AA second-level DISA 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) Finally, the AA third-level DISA 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 DISA 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 destination's 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 DISA OGM (busy message) has been recorded, the caller hears the DISA OGM (e.g., "The party you called is unavailable..."). If the assigned DISA 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 DISA 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.

Security Mode Intercom Calls Outside (CO) Line Calls All Security Trunk Security No Security

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 ( 1.10.8 Outside (CO) Line Call Limitation). 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]).

[Flowchart]

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.

•	The maximum recording time of each message is 3 minutes.
•	The preinstalled DISA/UCD OGM card can play only one message at a time and the total recording time of the PBX for DISA/UCD OGMs is 3 minutes. When an optional message expansion card for DISA/UCD OGMs 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 a DISA 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.
•	DISA OGM Mute Time Certain DTMF signals, such as Caller ID information, may be sent from the telephone company when a call is first connected. Because these signals may interfere with DISA, the PBX can be programmed to ignore DTMF signals for a specified amount of time ( OGM Mute Time [519]) after a call is connected. After the DISA OGM Mute Time passes, DTMF signals are recognised by the PBX and the DISA OGM begins playing or a short beep is sent.
•	SMDR The following are logged by SMDR for DISA calls ( 1.20.1 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 programme 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.
•	Fax Tone Detection 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 recognises the incoming signal as fax data ( FAX Tone Detection [514]). If the DISA OGM is short (0–5 s), in some cases the fax (CNG) tone may not be detected. In this case, it is recommended to set the length of time the PBX continues to search for a fax (CNG) tone after completing a DISA OGM to "10 s" or "15 s" through system programming ( DISA Wait Time after OGM [505]). If the assigned DISA OGM has not been recorded, it is recommended to set the length of time to "6 s" or "9 s" through system programming ( Intercept Time for Internal DISA [515]).
•	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]).

1.15.7 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 a user's personal message area or the PBX's common message area. 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 ( 1.16.2 Incoming Call Log). The optional voice message card has 2 voice message resources (Built-in Voice Message [BV] resource 1 and BV resource 2), and every extension must belong to one of these resources based on system programming ( BV Resource [621]). Extension users other than the operator or manager can access the following options:

– Personal BV outgoing messages (OGMs)

– Personal voice messages (left by callers via Call Forwarding [FWD] or Direct Message)

Messages can be recorded, played, and erased by that extension's user.

The operator or manager can access the following options:

– Personal BV OGMs for the operator or manager

– Personal voice messages (left by callers via FWD or Direct Message for the operator or manager)

– Common BV OGMs for the company

– Common voice messages (left by callers for the company)

Messages can be recorded, played, and erased by the operator or manager only.

Up to 125 voice messages with a total recording time of 60 minutes ( BV Total Recording Time [807]) can be logged per BV resource. All personal/common message areas within each BV resource share the total space of the resource. For example, in BV resource 1, if the common message area currently has 10 messages, totalling 10 minutes, the personal and common message areas can jointly store up to 115 messages or 50 minutes.

[Example: Pattern A]

[Example: Pattern B]

[Example: Pattern C]

If there are new voice messages in a user's personal message area or the common message area (if accessible), the user will hear a special dial tone (dial tone 4) when going off-hook. In addition, if that user's telephone has a MESSAGE button or Message/Ringer Lamp, the corresponding button or lamp will light when a message has been left. 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 BV feature allows users to also perform the following operations:

• If outside (CO) line calls are preprogrammed to be automatically directed to a common message area ( CO Line Mode—Day/Night/Lunch [414-416]), or if Direct Inward System Access (DISA) calls are preprogrammed to be redirected to a common message area via Intercept Routing ( DISA IRNA to BV—Day/Night/Lunch [438-440]), the caller will hear a common BV OGM and can leave a voice message directly in the common message area. [Programming Example] Outside (CO) Line No. Distribution method*1 DISA IRNA to BV*2 Day Night Lunch Day Night Lunch 1 BV01*3 BV02*3 BV02*3 Not Stored Not Stored Not Stored 2 DISA OGM3 DISA OGM4 Normal BV20*3 BV21*3 Not Stored (Cont.) : : : : : : : : : : : : : : 8 Normal Normal Normal Not Stored Not Stored Not Stored *1 CO Line Mode—Day/Night/Lunch [414-416] *2 DISA IRNA to BV—Day/Night/Lunch [438-440] Note This feature functions only when "DISA" is selected as the distribution method for the corresponding outside (CO) line port. *3 BVxx (xx=01–24): Common BV OGM number followed by the Common BV OGM feature number "722" In this example: If an outside (CO) line call is received on outside (CO) line 1: a) In day mode: The common BV OGM to be played ("BV01") for BV distribution is assigned. The caller hears the specified common BV OGM and leaves a voice message in the common message area. b) In night/lunch mode: The common BV OGM to be played ("BV02") for BV distribution is assigned. The caller hears the specified common BV OGM and leaves a voice message in the common message area. If an outside (CO) line call is received on outside (CO) line 2: a) In day mode: The DISA OGM to be played ("DISA OGM3") for DISA distribution and the common BV OGM to be played ("BV20") for DISA IRNA to BV are assigned. The call arrives on a DISA line and the caller hears the specified DISA OGM. When the destination does not answer the DISA call, the call is redirected to the common message area via Intercept Routing. The caller hears the specified common BV OGM and leaves a voice message in the common message area. b) In night mode: The DISA OGM to be played ("DISA OGM4") for DISA distribution and the common BV OGM to be played ("BV21") for DISA IRNA to BV are assigned. The call arrives on a DISA line and the caller hears the specified DISA OGM. When the destination does not answer the DISA call, the call is redirected to the common message area via Intercept Routing. The caller hears the specified common BV OGM and leaves a voice message 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 user's extension, or a call using the DISA AA service ( CO Line Mode—Day/Night/Lunch [414-416]), is forwarded to the user's personal message area, the caller will hear a personal BV 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 personal/common BV OGM has been recorded. When a caller leaves a voice message using this feature, the voice message is automatically linked to the caller information (including the extension number and name [if stored]) in the Incoming Call Log. • An extension user can play and/or erase voice messages from the user's extension. In addition, a user or the operator/manager can remotely play and/or erase voice messages through an outside (CO) line. The relevant voice message area is accessed by entering a preprogrammed voice message access code ( BV Access Code through CO Line [625]) while hearing a personal/common BV OGM or DISA OGM. Note If the Voice Mail Integration feature has been set, the BV feature will not function.

Conditions

•	Hardware Requirement: An optional voice message card.
•	The BV feature does not use OGMs for DISA/Uniform Call Distribution (UCD) on either the preinstalled DISA/UCD OGM card or the optional message expansion card for DISA/UCD OGMs (if present) ( 1.15.5 Outgoing Message (OGM) for DISA/UCD).
•	When an extension that belongs to BV resource 1 or BV resource 2 is reassigned to the other resource, the voice messages that were recorded prior to reassignment are erased, but the personal/common BV OGMs are not erased.
•	Each resource can only be accessed by one extension at a time. When the resource an extension is assigned to is being used by another extension, the extension cannot use that resource, even if the other resource is available.
•	The PBX can record a maximum of 125 voice messages per resource. The maximum recording time of each voice message ( BV Recording Time [214]) and the total recording time of the PBX ( BV Total Recording Time [807]) are programmable. The maximum recording time of each personal/common BV OGM ( Common/Personal BV OGM Recording Time [215]) is also programmable.
•	System programming determines the extension users that can use this feature ( BV for Extension [622]).
•	If a voice message channel (resource) is in use when an outside caller tries to leave a voice message, he or she will hear a ringback tone. The caller will hear a personal/common BV OGM as soon as a channel becomes available. Up to 8 outside (CO) line calls can be placed in a queue as they arrive.
•	If a user performs System Data Clear by selecting "All para" through system programming ( System Data Clear [999]), all voice messages except for personal/common BV OGMs are erased. To erase all voice messages and personal/common BV OGMs at once, initialise the voice message card through system programming ( BV Card Initialisation [808]).
•	Even if no flexible CO button is assigned as a Caller ID Indication—Personal button or a Caller ID Indication—Common button, a caller can leave a voice message in that personal/common message area and the Caller ID information, including associated voice messages will be logged.
•	When the remaining recording time for the PBX is less than 5 minutes, the display informs both the extension users within the same resource and the manager that the voice message resource is full, and the users will hear a special dial tone (dial tone 5) when going off-hook. If the remaining recording time goes back to being 5 minutes or more, for example, when messages are erased, the display returns to the idle status display and the users will hear another dial tone instead of dial tone 5 when going off-hook.
•	If the FWD feature is enabled for an extension whose FWD destination is the BV feature number ( Call Forwarding Selection [963]) and the extension has been assigned as "Normal" ( CO Line Mode—Day/Night/Lunch [414-416]), outside (CO) line calls to the extension will not be forwarded and the extension will not ring, even if the user has set the FWD feature. If FWD is disabled, outside (CO) line calls to the extension will not be forwarded and the extension will ring.
•	Only the operator or the manager can access the common message area (including common BV OGM). The operator has higher priority than the manager as follows:
	– When the operator extension is reassigned, the common voice messages (except for the personal BV OGM of the operator) that were recorded prior to reassignment are erased. The new operator can record, play back, and erase the common BV OGM. – When the operator, who does not share an extension number with the manager, is newly assigned, the common voice messages (except for the personal BV OGM of the manager) that were recorded prior to reassignment are erased. The operator can record, play back, and erase the common BV OGM. – When the operator, who does not share an extension number with the manager, is deleted, the common voice messages (except for the personal BV OGM of the operator) that were recorded prior to reassignment are erased. In this case, the manager can record, play back, and erase the common BV OGM.
•	A voice message area cannot be included as a member of a conference call.
•	Even if a caller does not leave a voice message in either the personal or common message area, for example, by going on-hook while hearing a personal/common BV OGM, the information is still logged in the corresponding Incoming Call Log (common or personal area) and displayed by SMDR ( 1.20.1 Station Message Detail Recording (SMDR)).
•	Personal/Common BV OGM Mute Time Certain DTMF signals, such as Caller ID information, may be sent from the telephone company when a call is first connected. Because these signals may interfere with BV, the PBX can be programmed to ignore DTMF signals for a specified amount of time ( OGM Mute Time [519]) after a call is connected. After the Personal/Common BV OGM Mute Time passes, DTMF signals are recognised by the PBX and the personal/common BV OGM begins playing.
•	A PT user can listen to voice messages by entering the Message Waiting Answer feature number.
