1.18 Voice Mail Features
1.18.1 Voice Mail APT Integration
Description
A Panasonic Voice Processing System (VPS) that supports APT Integration can provide many features and 
conveniences that are unachievable using traditional voice mail systems that rely on Inband (DTMF) 
Integration. 
 
Many of these features are explained below. For more information, refer to the Installation Manual supplied 
with the Panasonic VPS.
 
1.Automatic Configuration—Quick Setup (or DIP switch initialization without a PC) 
The PBX shares information with the VPS during setup that allows the VPS to automatically create the 
appropriate mailboxes for all extension numbers.
 
The following settings to enable APT Integration must be programmed through system programming to 
match the settings of the VPS. 
 
When 2 VPSs are connected to the PBX, note that each extension can have only one mailbox, but when 
the VPSs have executed Automatic Configuration, an extension has a mailbox in both VPSs. Therefore, 
an extension user must delete a mailbox in either VPS so that there are no duplicates. 
This example uses a Panasonic KX-TVS50 series VPS/KX-TVA50 series VPS, which can be connected 
with 4-conductor wire to 4 extension jacks of the PBX.
 
[Programming Example: Voice Mail Table]
In this example: 
When Port 7 & 8 is selected for VPS1, extension jacks 07 and 08 are placed in extension group 7 
automatically. Likewise, when Port 15 & 16 is selected for VPS2, extension jacks 15 and 16 are placed 
in extension group 8 automatically. Each extension group can be connected to only one VPS. Also the

idle extension hunting type is set as Circular Hunting, and the Voice Mail (VM) Hunting Chain and 
Automated Attendant (AA) Hunting Chain are automatically enabled in each of these 2 extension 
groups.
 
2.AA Service 
Allows the VPS to answer calls and direct callers to dial a number in order to connect themselves to the 
desired party (e.g., Enter the extension number of the desired party.). 
 
It is possible to access VM service from AA service to, for example, record messages. 
3.VM Service 
Allows callers to leave voice messages for specific parties, such as an extension user. Extension users 
can then listen to the messages left in their mailboxes at their convenience.
AA Service
A VPS can be used for the AA service as well as the VM service. When a call is directed to a port of the 
VPS that is in AA service mode, the caller will hear an outgoing message (OGM). After or while listening to 
the OGM, the caller may dial an extension number as directed (e.g., Enter the extension number of the 
desired party.). 
1.AA to Extension 
AA receives and answers outside (CO) line calls and offers services such as transferring to an 
extension or mailbox using DTMF signaling from the calling par ty.

2.Extension Backup 
If the VPS is assigned to ring with other extensions, for example the operator, for the same outside (CO) 
line, the VPS can be used as a backup for the operator when the operator cannot answer an incoming 
outside (CO) line call. 
 
In order to use this feature, Delayed Ringing must be set for the VPS ( Delayed Ringing—Day/Night/
Lunch [411-413]).
3.Status Notification to the VPS 
When a call is redirected to the VPS, the PBX sends the status of the called extension to the VPS. This 
allows the VPS to appropriately handle the call, playing the appropriate OGM for the caller. For 
example, if the called extension is in Do Not Disturb (DND) mode, the OGM (e.g., I am unable to 
answer your call right now, but I will get back to you shortly.) can be played.
 
VM Service
1.Accessing a Mailbox 
The PBX sends special messages to the VPS to indicate which mailbox should be accessed (Follow-
on ID).
 
2.FWD to a Mailbox of the VPS 
An extension user can set his or her calls to be forwarded to the VPS ( 1.3.1.2 Call Forwarding 
(FWD)). When a call is received at the extension, the PBX sends the extensions mailbox number to the 
VPS, and the VPS answers the call with the appropriate OGM (e.g., Hi, Im out of the office today...).

3.Intercept Routing to a Mailbox of the VPS 
Outside (CO) line calls via DISA ( 1.14.6 Direct Inward System Access (DISA)) can be programmed 
to be automatically redirected to an extension users mailbox when the extension user does not or 
cannot answer them (
 1.1.1.2 Intercept Routing). The VPS can answer the call with an OGM (e.g., I 
cant take your call now...) and callers can leave messages in the mailbox. In order to use this feature, 
a voice mail extension number must be assigned as the intercept destination for the original destination 
extension that received the call (
 CO Line Mode—Day/Night/Lunch [414-416], Flexible Ringing—
Day/Night/Lunch [408-410], Delayed Ringing—Day/Night/Lunch [411-413]), and Intercept must be 
selected through system programming ( DISA Intercept Mode [507]). 
4.Transferring to a Mailbox of the VPS 
Extension users can transfer calls to a mailbox, after which callers can leave a message for the desired 
party. While answering a call, the extension user simply presses the VM Transfer button and enters the 
extension number of the party the caller wishes to leave a message for. The VPS will answer the 
transferred call and record a message into the appropriate mailbox.
VM Transfer Button 
In order to use this feature, the extension user must use a flexible CO/Direct Station Selection (DSS) 
button customized as a VM Transfer button. A voice mail extension number must be assigned to the 
button when creating it.
 
5.Listening to Recorded Messages 
After the VPS records a message, it will light the appropriate lamp or button on the extension for which 
the message was intended, to indicate that there is a new message (
 1.16.1 Message Waiting). The 
proprietary telephone (PT) user can play the message back simply by pressing the MESSAGE button 
used for mailbox access; he or she does not need to enter a mailbox number. A single line telephone 
(SLT) user hears a special dial tone (dial tone 3) when going off-hook if there are any messages in his 
or her mailbox, and can play the message back by entering the Message Waiting Answer feature 
number. 
 
6.Live Call Screening (LCS) 
Similar to a conventional home answering machine, LCS allows a PT user to monitor his or her own 
mailbox as a caller is leaving a message and, if desired, answer the call simply by pressing the LCS 
button. 
 
PT users can choose one of 2 ways to perform LCS, through personal programming (Live Call 
Screening Mode Set):
Hands-free mode: The user can screen calls automatically through the built-in speaker.
Private mode: The user will hear an alert tone when a message is being recorded in his or her mailbox. 
To screen calls, the user must press the MONITOR, SP-PHONE, or LCS button.

LCS/LCS Cancel Button 
A flexible CO/DSS button can be customized as an LCS or LCS Cancel button.  
7.2-way Recording into the VPS 
PT users can record their own telephone conversations. These recordings can be stored in the PT 
users own mailbox (2-way Record) or in another users mailbox (2-way Transfer), depending on which 
button the user presses to begin recording.
2-way Record/2-way Transfer Button 
A flexible CO/DSS button can be customized as a 2-way Record or 2-way Transfer button.
Note
You should inform the other party that the conversation will be recorded before beginning to record 
any telephone conversation.
Conditions
[General]
 A VPS can be assigned as the destination for the following features:
– FWD—All Calls
–FWD—Busy/No Answer
– DISA Intercept Routing—No Answer (IRNA)
For these features, the caller does not need to know the mailbox number of the called extension 
because the code is automatically transmitted to the VPS. If a DISA call is forwarded to the VPS by the 
IRNA feature from a DISA ring group, the PBX will send the VPS the mailbox number of the extension 
within the DISA ring group that is connected to the lowest-numbered jack.
[Live Call Screening (LCS)]
 To prevent the unauthorized screening of calls, a 3-digit password must be entered when activating LCS 
for an extension. If the user forgets his or her password, it can be cleared by the operator or manager 
(LCS Password Control).
 If an extension user is screening a call and then goes off-hook to answer it, the VPS will either stop or 
continue recording the message, according to system programming (
 LCS Recording Mode Set 
[620]).
 If a call arrives while an extension user is having a conversation with another party and the extension 
has Call Waiting activated, the user will hear a call waiting tone. The user can put the existing call on 
hold before accessing LCS.
[2-way Recording into the VPS]
 If all ports of the VPS are busy when a user tries to record a conversation:
– The user hears an alarm tone when pressing the 2-way Record button.
– The user hears an alarm tone after pressing the 2-way Transfer button followed by an extension 
number.

1.18.2 Voice Mail Inband (DTMF) Integration
Description
A Panasonic Voice Processing System (VPS) or similar product from another manufacturer can provide 
Automated Attendant (AA) and Voice Mail (VM) services when connected to the PBX. 
 
The VPS and PBX communicate with each other by sending DTMF (Dual Tone Multi-Frequency) signals. 
For more information, refer to the documentation provided with the VPS.
1.AA Service 
Allows the VPS to answer calls and direct callers to dial a number in order to connect themselves to the 
desired party (e.g., Enter the extension number of the desired party.). It is possible to access VM 
service from AA service to, for example, record messages.
 
2.VM Service 
Allows callers to leave voice messages for specific parties, such as an extension user. Extension users 
can then listen to the messages left in their mailboxes at their convenience.
AA Service
A VPS can be used for the AA service as well as the VM service. When a call is directed to a port of the 
VPS that is in AA service mode, the caller will hear an outgoing message (OGM). After or while listening to 
the OGM, the caller may dial an extension number as directed (e.g., Enter the extension number of the 
desired party.).
 
If the VPS transfers a call via the AA service, the PBX will inform the VPS of the status of the called party 
using a DTMF status signal so that the VPS will know the status. This enables the VPS to quickly play an 
appropriate OGM to the caller (e.g., Im handling another call now..., Im away from my desk now..., etc.).
 
The DTMF status signals sent by the PBX are explained below.
