Panasonic KX-TVP200 Installation Manual page 51

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.)
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.
