Using The Other Telephone Features

7.19Using Direct Inward System Access (DISA)

This 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 disconnect supervision. While DISA will function, Comdial 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
