Other Features

Direct Inward System Access (DISA)

The Direct Inward System Access (DISA)* feature allows you to call into the
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 that 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 that the installer has programmed for the line that 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 leave a
message.
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 prompt
directions to complete your call. Further, some systems with voice prompt
enhancement, provide a one-digit menu that prompts 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 discon-
nect supervision. While DISA will function, Comdial will not be liable for
its performance under any condition where disconnect supervision is not
provided. Check with your installer for complete details.
* 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 unau-
thorized 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, relat-
ing to unauthorized or fraudulent access or use, or unaccounted-for access or use.
