1.2 Voice Mail Integration
1.2.1 Overview
In order for the VPS to function, it must be integrated with the PBX it is connected to. 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.
DPT Integration
When the VPS and PBX use DPT Integration, voices and data are sent digitally. The most significant
advantage of DPT Integration is that the 2B+D communication provides 2 VPS ports for each port.
DPT Integration requires the proper software level in the PBX as well as 4-conductor connections for
each jack. In order for the VPS to function properly using DPT Integration, the PBX and VPS must be
programmed to work together. For a list of PBXs that are compatible with DPT integration, see 1.1.7
Compatible PBXs.
To use DPT Integration, the lowest numbered jack of the VPS must be connected to the lowest
numbered jack assigned as a Voice Mail Port Assignment in the PBX. See the DPT connection
example(s) for your VPS model in the following sections:
1.2.2 Connection Examples—KX-TVM50
1.2.3 Connection Examples—KX-TVM200
Connect the other jacks to the VPS in the same order as they are found in Voice Mail Port Assignment
in the PBX.
APT Integration (TVM50 only)
When the VPS and PBX use APT Integration, voices are sent using analogue technology, and data
is sent digitally. APT Integration requires the proper software level in the PBX as well as 4-conductor
connections for each jack. In order for the VPS to function properly using APT Integration, the PBX
and VPS must be programmed to work together. For a list of PBXs that are compatible with APT
integration, see 1.1.7 Compatible PBXs.
Inband Integration (TVM50 only)
When the VPS and PBX use Inband Integration, voices are sent using analogue technology, and data
is sent using analogue DTMF tones.
No Integration (TVM50 only)
When the VPS and PBX use no integration, voices are sent using analogue technology and data is
sent to the VPS through the use of standard audio signals, such as DTMF tones, busy signals,
ringback tones, etc.
