b) Message Button Sequence
If the extension has messages and the MESSAGE button is turned on by the KX-TVP series VPS, it can
playback its own messages from the mailbox of the VPS by pressing the MESSAGE button. If the VPS
controlls the MESSAGE button while the port is not in the VM service mode, you cannot open your
mailbox. Therefore the KX-TVP VPS allows you to open the mailbox and playback the message only
when the port is in a VM service mode.
The KX-TD500 solves this problem by the "Message Button Sequence". When this sequence is sent to
the VPS port, the port works as a temporary VM service mode. If the MESSAGE button is turened on by
the VPS, the KX-TD500 automatically connects it to the VPS and sends this sequence when the
extension MESSAGE button is pressed.
Example:
If you program all of the VPS ports to control the extension MESSAGE buttons, AA service ports may
control the MESSAGE button after recording a message.
When the "Message Button Sequence" is programmed as
Number), the KX-TD500 accesses the VPS and sends this sequence to the VPS when you press the
MESSAGE button. "#6" is the command which makes the KX-TVP series VPS port a VM service. 'Y' is
the command for playing back a message from the VPS.
The "Message Button Sequence" is programmed as "#6YH" (Dial '#', '6', 'Y'
and each extension's mailbox number). "#6Y" is the service command
which makes the VPS port work as a VM service and plays back a message.
This sequence depends on your VPS system. Refer to your VPS manual.
