1.15.1 Doorphone Call
Description
A visitor can use a doorphone to call its preprogrammed destination. Extension users can call 
a doorphone.
Conditions
Hardware Requirement: An optional doorphone and DPH card. 
Call Destination
The destination of doorphone calls can be assigned to each doorphone port for each time 
mode (  Doorphone Call Destination [720]). The Time Table is determined by the tenant 
number assigned to each doorphone port. (  2.2.4 Time Service) 
Certain destinations cannot be the destination of doorphone calls. (  1.1.2.1 Internal Call 
Features—OVERVIEW)
Class of Service (COS) programming determines the doorphone ports that are able to 
make an outgoing CO line call.
Internal Call Block (  1.1.2.2 Internal Call Block) determines which extensions can call a 
doorphone. 
Ring Duration
If an incoming doorphone call is not answered within a preprogrammed time period, 
ringing stops and the call is canceled.
Call Duration
The duration of doorphone calls can be restricted by a system timer. If the timer expires, 
the call will be disconnected.
Door Open
While engaged on a doorphone call, an extension user can unlock the door to let the visitor 
in. (  1.15.2 Door Open)
A doorphone number can be referenced for each doorphone port (  Doorphone Number 
Reference [729]).
Certain pairs of doorphones (doorphones 1 and 2, and doorphones 3 and 4) cannot make 
or receive calls simultaneously.
If a visitor presses the doorphone button while the other doorphone is engaged in a call, 
he or she will hear no tone. If an extension user calls a doorphone while the other 
doorphone is engaged in a call, the extension user will hear a busy tone.

1.15.5 Outgoing Message (OGM)
Description
An extension assigned as a manager (manager extension) can record outgoing messages 
(OGMs) for the following features:
Conditions
Hardware Requirement: An MSG card.
Number of Messages and Recording Time
The PBX can record a maximum of 32 messages. The maximum recording time of each 
message is one minute. Note that the total recording time of the PBX is 8 minutes.
A floating extension number can be assigned to each outgoing message (OGM) (  
Outgoing Message (OGM) Floating Extension Number [730]).
Each MSG card can play two messages simultaneously. Adding additional MSG cards 
increases the number of messages that can be played simultaneously, but does not 
increase the total recording time or the number of messages that can be recorded.
[Example]
Note
When an additional MSG card is added, it is blank—all necessary messages will need 
to be stored in the new card. This can be done in two ways:
a)By installing the new MSG card then recording each message again. The PBX 
will automatically store the new recordings in each MSG card. Feature Usage Details in

b)By transferring messages from the PBX to a PC using KX-TAW848 Maintenance 
Console, then transferring them back to the PBX with the new MSG card 
installed.
The same message can be played to multiple callers simultaneously.
Recording Methods
a)Record voice messages through the extension telephone.
b)Transfer prerecorded voice messages from an external audio source to the PBX via 
an external music port.
Note
Record voice messages only; avoid the recording of music.
After recording messages, a manager extension can also play them back for confirmation.
A progress tone is sent to a manager extension before recording messages for a 
preprogrammed time period, or while clearing a prerecorded message assigned to a 
floating extension number.
Record a message when PBX traffic is light, such as early morning or late evening.
When a manager tries to record a message, he or she will hear a ringback tone if a 
message channel is in use. When all ports of the MSG card(s) become idle, the manager 
will hear the progress tone for a preprogrammed time period, then the PBX will 
automatically switch to the recording mode.

2.1.5 Outgoing Messages (OGM)
1.15.6 Direct Inward System Access (DISA)
Description
Direct Inward System Access (DISA) allows outside callers to be connected to their desired 
PBX destinations without the use of an operator. Callers can listen to an outgoing message 
(OGM) instructing them as to which numbers to dial to be connected to the person or 
department they would like to speak with.
DISA can also give PBX users access to PBX features, such as making CO line calls or 
changing their extension settings, when they are outside the office.
To use DISA, the incoming call must first be directed (via DIL distribution) to a floating 
extension number assigned to an OGM used by DISA. This OGM can then guide callers and 
allow them to:
Make an intercom call to an operator, extension, or to a floating extension number, 
such as an incoming call distribution (ICD) group or a modem used for remote system 
administration.
Call another outside party via the CO lines of the PBX. 
						

							1.15 Optional Device Features
106 Feature Guide
Set or operate PBX features, such as Call Forwarding (FWD) or Extension Lock, 
remotely.
OGM
When a call is directed to a floating extension number assigned to an OGM used by DISA, 
callers will hear the OGM. If using the DISA Automated Attendant (AA) service, this OGM will 
direct callers to press the appropriate digit (DISA AA number) to be connected to a specific 
destination. To access other PBX features, such as making intercom or CO line calls, the caller 
may dial the appropriate numbers while the OGM is playing.
Any extension assigned as a manager can record an OGM. (  1.15.5 Outgoing Message 
(OGM))
DISA AA Service
DISA AA service allows a caller to dial a single-digit number (DISA AA number) and be 
connected to the desired party automatically. Each DISA OGM can be assigned up to ten 
destinations that can be called by dialing a DISA AA number (0–9). These destinations can be 
any destination within the PBX which has an extension number or floating extension number.
After or while listening to the OGM, the caller may dial a DISA AA number as directed by the 
OGM. (Press 1 to speak to Sales. Press 2 to speak to Support.) Each DISA AA number 
directs the call to a preprogrammed location, which can even be another DISA floating 
extension number (Multistep DISA AA Service).
Since DISA AA numbers are single-digits, if the caller dials a second digit within a 
preprogrammed time period (DISA Second Digit Time for Automated Attendant), DISA AA 
service will be bypassed because the PBX will assume the caller is trying to access a specific 
feature.
[Programming Example: DISA OGM Setting]
Each DISA OGM can be assigned a floating extension number, a destination for each DISA AA 
number, and the OGM number of the OGM played when the called destination is busy or in Do 
Not Disturb (DND) mode.
DISA Intercept Routing—No Dial
If the caller fails to dial any digits within a preprogrammed time period (DISA First Digit Time 
for Routing to Operator When No Dial) following the OGM, the call is redirected to an operator 
extension.
DISA Intercept Routing—Busy/DND
If the destination of a DISA call is in DND mode or is busy (and has not set Call Waiting or 
FWD), the call will be redirected to an idle extension in the destination’s idle extension hunting 
group. (  1.2.1 Idle Extension Hunting) If no extension in the group is available, or if the 
destination of the DISA call is not a member of an idle extension hunting group, the call will be 
handled in one of the following ways, according to system programming:

a)Busy Tone: The caller hears a busy tone.
b)Intercept Routing: The call will be routed to the Intercept Routing—Busy/DND 
destination assigned for the extension.
c)OGM: An OGM used only for when the destination is busy or DND can be played for 
the caller. (The par ty you called is unavailable...)
DISA Intercept Routing—No Answer
If the destination of a DISA call does not answer the call within a preprogrammed time period 
(DISA Intercept time) (  DISA Intercept Time [211]), the call will be redirected to the 
preprogrammed intercept destination. (  1.1.1.4 Intercept Routing)
If the intercept destination does not answer the call within a preprogrammed time period (DISA 
Disconnect Time after Intercept) after the DISA Intercept time expires, the call will be 
disconnected.
Call Retry
While hearing a ringback, reorder, or busy tone, the caller can press   to retry the call. 
When a DISA call is retried, the caller will hear the original DISA OGM once again and can 
make the same or a different selection.
During a CO-to-CO line call, the caller can press   to disconnect the CO line call and return 
to the original DISA OGM. If Mode When DISA Receives DTMF * is set to Send DTMF 
* the   tone will be sent—the call will not be retried.
DISA Security Mode
Security can be enabled for the PBX to control the types of calls that can be made by callers 
using DISA. (  DISA Security Mode [732]) However, note that the security setting does not 
effect DISA AA calls (AA calls can only be made to preprogrammed destinations and security 
is not an issue) or Operator Calls (  2.2.5 Operator Features).
Walking COS/Verified Code Entry through DISA
While the OGM is playing, DISA callers can use Walking COS (  1.8.4 Walking COS) and 
Verified Code Entry (  1.8.5 Verified Code Entry) to:
a)Make calls via DISA which are prohibited by the DISA Security Mode
b)Gain access to certain features, such as FWD, Extension Lock, etc. (Walking COS 
only)
This feature is particularly useful when a PBX user needs to make a business call while at 
home, or when an extension user forgets to set FWD on his or her extension before leaving the 
office.
All privileges and restrictions on making calls that apply when the user is using an extension 
telephone are also applied when using Walking COS or Verified Code Entry through DISA.
Additionally, setting features by using Walking COS through DISA can be enabled or disabled Security Mode Intercom Calls CO Line Calls

through system programming for each Class of Service (COS). (  1.22.5 Remote Extension 
Control by User)
CO-to-CO Line Calls through DISA
DISA callers can use DISA to make CO line calls in either of the following situations:
a)When the DISA Security Mode allows CO line calls
b)When the caller uses Walking COS or Verified Code Entry through DISA, and his or 
her COS allows CO line calls.
If a call between two outside parties is established via DISA, the length of the call can be limited 
to a preprogrammed duration. (  1.10.7 CO Line Call Limitation) A timer will activate when 
the call is connected, and a tone will be heard 15 seconds before the timer expires at five-
second intervals.
At this point the call can be extended for a preprogrammed amount of time (  DISA CO-to-
CO Line Call Prolong Time [210]) by pressing any dialing button excluding  . 15 seconds 
before the extended time runs out, the tone will be heard again.
The number of times a CO-to-CO line call can be extended is also programmable; if set to 0, 
calls can be extended as many times as needed.
If the caller wishes to end the CO-to-CO line call but remain connected to the PBX in order to 
make other calls or access other DISA features, the caller can press   at any time to return 
to the original DISA OGM (Call Retry).
