3.1 GUIDELINES FOR INTEGRATION

INTEGRATING THE VPS WITH PANASONIC KX-T PHONE SYSTEMS
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., salespeople 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.
Follow-on ID or Called Party ID
When forwarding or transferring a call to the VPS, a PBX with Follow-on ID sends the mailbox
number of the called subscriber to the VPS before connecting the caller. The VPS responds by
playing that subscriber's personal greeting. This operation is sometimes called Call Forward to
Mailbox. Without this feature, the VPS cannot immediately play the greeting when the line is
busy or there is no answer and allow the caller to leave a message.
TEST: See if dialing the On code from an SLT can turn on an extension's
message waiting indicator.
TEST: Place an outside call from an SLT. See if you can set up a screened
transfer to another extension. Next, try the same test with an internal call.
(The VPS may have to transfer both types of calls.)
