Direct Inward System Access (DISA)

What's this?
With Direct Inward System Access (DISA) remote users can access and use the system's features and facilities
using Trunks, on which this feature is enabled.
Using DISA, remote users can:
• call any extension.
• make external calls.
• use features and facilities of the system.
• configure features and facilities of the system and administer the system.
All these can be done as if being done from a local extension of the ETERNITY NE.

DISA Variants

ETERNITY NE offers three types of DISA, each with a different method of authentication and level of access:

PIN Authentication - Multiple Calls

Callers can access an extension of ETERNITY NE by dialing the DISA Login Code consisting of:
• the DISA Feature Access Code.
• the extension number they want to access.
• the User Password of that extension.
The callers are authenticated and allowed to use the extension on which they are logged in.
The callers must dial special digits or codes to go On-hook, Off-hook. They are allowed to make as many trunk
calls and internal calls as long as they are logged into the DISA mode.
To end the DISA login session, callers must dial the Termination code or disconnect from the remote end.
Callers can access an extension to use DISA PIN Authentication-Multiple Calls only if the extension has DISA
feature enabled in its Class of Services.

DISA with CLI Authentication - Multiple Calls

The system authenticates the caller by matching the caller's CLI with the entries of the DISA-CLI Authentication
Table and logs in the caller into the extension configured as 'Auto Login' extension for the CLI.
Callers are not required to dial any DISA Login Code or any password.
When the caller is authenticated on the basis of CLI, the system plays the ('internal' system) Dial Tone.
The callers must dial special digits or codes to go On-hook, Off-hook. They are allowed to make as many trunk
calls and internal calls as long as they are logged into the DISA mode.
To end the DISA login session, caller must dial the Termination code or disconnect from the remote end.
For this type of DISA, the DISA CLI Authentication Table must be configured first.
