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
