4.1 Guidelines for APT/DPT Integration
4.1.1 What is APT/DPT Integration?
In order for the VPS to function, it must be integrated with the PBX it serves. The type of integration that is
used determines how voice (caller messages, VPS prompts, etc.) and data (extension status, button presses,
etc.) are sent between the VPS and the PBX.
Unlike Inband Integration, when the VPS and PBX use APT or DPT Integration, information is sent between
the PBX and VPS digitally. This allows the VPS to respond quickly and efficiently.
Additionally, configuring a Panasonic PBX for APT or DPT Integration is generally much easier than configuring
a PBX for Inband Integration.
4.1.2 When to Use APT/DPT Integration
The type of PBX and/or the type of extension cards installed in the PBX will determine whether APT or DPT
Integration can be used. See 1.1.7 Compatible PBXs for more information.
4.1.3 APT/DPT Integration Features
During APT/DPT Integration, the PBX sends information to the VPS which lets the VPS know from where and
why a call is sent to the VPS, and identifies the extension or outside caller that is calling. This communication
allows features that are only available with APT/DPT Integration, described below:
Feature Description
Compatible
Integration Type
APT DPT
Auto Configuration The VPS knows what extension names/numbers exist on
the PBX and creates mailboxes for each extension
automatically. Also sets the VPS clock with data from the
PBX clock.
ü ü
Automatic Login
*1
Subscribers can access their mailboxes without dialing
their mailbox numbers.
ü ü
Caller ID Call Routing
*2
The VPS automatically sends calls from preprogrammed
Caller ID numbers to the specified extension, mailbox, or
Custom Service.
ü ü
Caller ID Screening When the VPS transfers a call to an extension, the VPS
announces the prerecorded name of the caller, allowing
the extension user to know who is calling.
ü ü
Caller Name
Announcement (System/
Personal)
*2
The VPS announces the prerecorded caller name when:
(1) extension users listen to messages from assigned
numbers left in their mailboxes, (2) the VPS transfers
calls from assigned numbers to the users, and (3) the
VPS pages the users by intercom.
If the same Caller ID number is programmed for both
System and Personal Caller Name Announcements, the
VPS will use the personal caller name.
