7.16 Using Direct Inward System Access (DISA)
This feature allows you to call into the DXP digital communications
system from an external telephone. You can call directly to intercom
extensions and talk to the intercom parties or, if the system includes a
voice mail option, leave messages for them if they are not available.
When you call the DISA telephone number and dial your authorization
code, the system treats your call as it would treat one coming from a
system telephone and permits you to use many of the same features you
can use when you are calling from your assigned station. (Authorization
codes are associated with personal or group intercom numbers and are
assigned to you by your installer when he or she programs the system.) If
you use your DISA access to make a call through the system and out on
an outside line, the system applies all the toll restriction and automatic
route selection to the call the installer has programmed for the line you
are using. If you dial an incorrect authorization code, or the system is
busy with other DISA calls, you will either hear an error tone, or the
system will automatically route your call to one of the following areas
(as determined by your system installer):
a designated station where you can talk to the system attendant,
a digital voice announce that will prompt you to take additional
action,
a proprietary voice mail station where you will be prompted to
leaveamessage.
The system allows you three tries at dialing your authorization code
before it routes your call as detailed above.
Some systems provide voice prompts to DISA callers and other systems
do not. If you encounter voice prompts when you call on the DISA line,
follow the voice prompt directions to complete your call.
Further, some systems with voice prompt enhancement provide a
one-digit menu prompting you to dial a single digit to reach available
departments, use system features, or obtain operator assistance.
NOTE: DISA is not recommended for use on loop start lines without
disconnect supervision. While DISA will function, we will not
be liable for its performance under any condition where
disconnect supervision is not provided.
Comdial has taken reasonable steps in the design of all product features,
including DISA, which protect against unauthorized or fraudulent access
to, or use of, a system, or which protect against unauthorized, fraudulent
or unaccounted-for access to, or use of, long distance lines. However, no
system is entirely invulnerable or immune from unauthorized or
fraudulent access or use, or unaccounted-for access or use, and therefore
Comdial disclaims any and all liability, and makes no warranty, express
or implied, relating to unauthorized or fraudulent access or use, or
unaccounted-for access or use.
