Multiple Directory Numbers
Strata DK General Description 6/00 83
Phantom Directory Number [PhDN]
This is an additional [DN] that can be dedicated to a station or to a group of stations (usually in the
same area or department). Each unique [PhDN] can only appear once on a given telephone, but
each telephone can be assigned up to eight different [PhDNs].
Any [PhDN] can appear on all Toshiba telephones in the system. A [PhDN] can ring on up to 120
telephones in the system. Each [PhDN] must be assigned to a designated telephone owner via
system programming.
Each [PhDN] is flexibly assigned to an owner telephone in system programming. Only [PhDN]
owner telephones have the following privileges:
♦ Set Call Forward for [PhDNs]
♦ Set Call Forward Mailbox destination for [PhDNs]
♦ Receive Message Waiting (MW) indication for up to four [PhDNs] on individual Phantom
Message Waiting [PhDN/MW] LEDs
♦ Receive OCA when the [PhDN] is called

Notes
● Incoming calls come in to a telephone’s [PDNs] from the top down to prevent “call
collisions.” For example, incoming calls to Stations 200’s [PDN] will first ring the top
“200-1” line, a second call will ring “200-2” below it, and a third call will ring “200-3.”
Auto preference to select a [DN] to make a call by going off-hook is from the bottom
[PDN] up. This avoids answering an incoming call while attempting to originate a call.
● Each [PhDN] can have a dedicated Message Waiting [PhDN/MW] LED/button to notify
the [PhDN] owner telephone user that there is a message for the person or department
associated with the [PhDN]. Up to four [PhDNs/MWs] can be programmed onto the
flexible buttons of each telephone. In the above example, [MW/500] is the Message
Waiting button for [PhDN 500].
● A station [PDN] shows busy on Busy Lamp Field when the station is in DND mode or off-
hook on any [DN], CO line or Tie line. [PhDNs] do not display Busy Lamp indication.
