Panasonic KX-TVM50 installation manual Follow-on ID or Called Party ID

5.1 Guidelines for Inband Integration

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 notifies the caller 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: Place a trunk call from an SLT. See if you can set up a screened transfer to another extension. Next, try the same test with an intercom call. (The VPS may have to transfer both types of calls.)

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 called extension's greeting message when the line is busy or there is no answer because the VPS does not know which mailbox to send the caller to.
