INTEGRATING THE VPS WITH PANASONIC KX-T PHONE SYSTEMS
46 Installation Manual
If the PBX does not provide station-to-station touchtone signaling, VPS services and
features will be limited.
Message Waiting Notification from an SLT
The PBX extensions should light a lamp or receive stutter dial tone when the Message-Waiting-
Lamp-On code is dialed by the VPS. The VPS functions best when the extension number of
the voice mailbox owner follows the Light-On or Light-Off code. On some PBXs, however, the
extension number is dialed first, followed by a hookswitch flash and then the On code. This
presents a problem if the extension is answered before the VPS sends the hook-switch flash.
If the PBX does not provide message waiting notification from an SLT, the VPS can only
notify mailbox owners by dialing a beeper number or user-assigned extension.
This process slows down VPS performance as it dials the beeper or extension number and waits
to confirm notification. The beeper or user-assigned extension notification is meant to be used
for necessity, usually for mailbox owners who are often out of the office (e.g., sales people or
field representatives). The only other option, without message waiting notification, is for
mailbox owners to periodically call the VPS to check for messages.
Screened Transfer from an SLT
The PBX must provide a screened transfer from an SLT for the VPS to function properly.
A screened transfer:
1.
Puts the caller on hold, usually with a hookswitch flash.
2.
Dials the extension.
3.
Checks to see if the called subscriber is in, out, or on another line, and whether or not that
subscriber accepts the transfer.
4.
Completes the transfer (by going on-hook) or returns to the caller to say that the party is
busy or not available. It then gives the caller an opportunity to leave a message.
If the PBX does not provide screened transfer from an SLT, the VPS cannot give callers the
option to leave a message in a subscriber's mailbox.
TEST:Call an SLT extension from the telephone in question. When the call
is answered, see if the person receiving the call hears touchtones when
numbers are dialed.
TEST: See if dialing the On code from an SLT can turn on an extension's
message waiting indicator.
