1236 Matrix ETERNITY NE System Manual
• The Password must be dialed by the caller before the expiry of this timer.
• The VMS checks if the Password is valid.
• The Password is valid and the DISA Login is successful. The caller is logged into the dialed Extension
Number.
• The VMS hands over the DISA call to the SARVAM UCS.
• When the caller goes Off-hook by dialing the Off-hook code #1, the system plays the internal dial tone and
waits for the caller to dial digits.
• If the caller dials an external number using a CO trunk, the system starts the DISA Inactivity Timer
(configurable; default: 2 minutes).
• The system waits for the caller to dial digits within the DISA Inactivity Timer.
• The system reloads this timer each time it receives digits from the caller. If the caller fails to dial any digit
within this timer, the system plays beeps for the duration of the DISA Warning Beeps Timer (fixed; 15
seconds). If no digit is received at the end of the Warning Beeps, the system terminates the DISA session.
If digits are received before the end of the Warning Beeps, the system reloads the DISA Inactivity Timer.
• The caller can make as many trunk calls and internal calls as the caller wants.
• The caller can terminate the DISA login session either by disconnecting from the remote end or by dialing
the Termination Code #9.
The VMS plays the default Greeting Message, Welcome Greeting and DISA prompts to the callers. You can
customize them as per your requirement, if required.
