Directory Number [DN] Buttons
The [DN] buttons consist of: [PDNs], [SDNs], and [PhDNs]. They are used to initiate or answer a call
and are known as your extension or intercom number(s). You can have multiple [DN] buttons on your
telephone (see
Incoming calls ring your telephone's [PDNs] from the top down. For example, incoming calls to
Station 210's [PDNs] first ring the "210-1" button, then "210-2," and finally "210-3." Your [PDN] is
considered busy only when all of the [PDNs] are being used by your telephone or other telephones,

Press to answer a call to the Primary Directory Number or to initiate a
phone call. The [PDN] is specifically your Extension Number or Intercom
Number. Your telephone can have up to four [PDN] buttons with your
number. You can set Call Forward and Voice Mail ID code for your
[PDN].
A [PDN] of another telephone which appears on your telephone is
considered a [SDN]. You cannot set Call Forward and Voice Mail ID
code for [SDNs] on your telephone.
Up to eight Phantom Directory Numbers can be dedicated to a station or
shared by a group of stations. One example of a Phantom Directory
Number application is when it is used as a common phone number for
an entire department. For instance, when the [PhDN] appears on a
group of telephones, such as the Sales Department, it will ring on all of
the telephones of the group when it is called. You can only set Call
Forward and Voice Mail ID code for [PhDNs] that are owned by your
telephone. You can have a separate message waiting button and
mailbox for up to four [PhDNs] on your telephone.
