Primary [DN] Buttons
Primary Directory Number buttons [PDNs] are needed to make calls and receive calls. It is a
telephone’s main extension number. Each telephone is assigned only one [PDN] and that telephone
is designated as the owner of the [PDN]. This [PDN] button can be made to appear multiple times
on the owner telephone and on other telephones (see Phantom [DN] Buttons). Features, Class of
Service, etc., are associated only with the station assigned as the owner of the [PDN]. [PDNs] that
appear on telephones other than the owner telephone are referred to as Secondary DNs [SDNs].
Phantom [DN] Buttons
Phantom [DN] buttons [PhDNs] are additional directory numbers appearing on telephones as
extension buttons. [PhDNs] can be used as independent extensions on the phone or can appear on
multiple phones to be used to allow call handling for departments or groups of telephones.
[PhDNs] can be used to make a telephone appear to have multiple [PDN] extension buttons. When
assigning a [PhDN] for use as another appearance of the [PDN], the display properties are set the
same as the [PDN] and a hunting sequence is set up to roll the calls from the [PDN] over to the
other [PhDN]s associated with the [PDN]. With this arrangement, Call Forward will send calls to
the [PDN]’s destinations and Voice Mailbox.
Pilot [DN]
A Pilot [DN] is a pseudo-location that is assigned a [DN] where calls may be directed. Unlike
[PDNs] and [PhDNs], a Pilot [DN] is
not a button on any telephone. A Pilot [DN] is used as a
device where calls can ring and be held while an external application using the Computer
Telephony Interface (CTI) can control the call. To ensure calls do not get lost in the Strata CTX, a
time-out and overflow service is provided to redirect the call when the link is down. Calls being
held on the Pilot [DN] using the CTI link can specify any of the 15 on-hold music sources that are
possible on the Strata CTX.
Pilot DNs are also assigned to Station Hunt Groups (for details, refer to Station Hunting).
Distinctive LED Indicator
System Availability: All systems
Each feature button on a digital telephone has a Light Emitting Diode (LED) indicator. Distinctive
LED indicators provide a method for quickly identifying the status of a line or feature button. The
LED color or flash pattern can identify the call you are currently on, as well as other calls you are
controlling, versus other calls that may appear on your telephone. Each telephone uses dual-color
LEDs: green for lines you are using; red for lines used by someone else.
Distinctive Ringing
System Availability: All systems
Users sometimes need to distinguish the ringing of one button on their phone from another button
and sometimes stations in close proximity to one another need to distinguish the calls on one desk
from another. Typically, multiple sounds are used to provide this distinction. Distinctive ringing
can be assigned to each
Line or [DN] button on each telephone.
With Strata CTX Release 1.3 and higher, you can set up to ten different incoming ringing tones for
internal, as well as external calls. Previously, distinctive ring was not provided for internal calls.
