Matrix PRASAR UCS System Manual 811
To end the DISA login session, callers 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.
DISA with CLI Authentication - One Call
This type of DISA is similar to the previous one. The system authenticates callers by matching the callers’ CLI with
the entries of the DISA-CLI Authentication Table and logs the callers in to the extension designated as ‘Auto Login’
extension for the CLI.
When the caller is authenticated on the basis of CLI, the system gives the caller direct access to the Outgoing
Trunks selected for TAC-1 for the current time zone (working hours, break hours, non-working hours) in the “Station
Basic Feature Template” assigned to the Auto Login extension. It plays the dial tone.
Callers are allowed to make a single external call. The system ends the DISA session on the completion of the call
by the caller or by the other remote party.
For this type of DISA, the DISA CLI Authentication Table must be configured first.
To make another call, the caller must enter the DISA mode again, by calling the PRASAR UCS from the remote
location.
DISA with CLI Authentication - One Call is generally used when PRASAR UCS is deployed in the Gateway Mode,
where PRASAR UCS is configured to send an answer signal to the caller/calling device, receive the DTMF digits
dialed by the caller/calling device and dial out the digits dialed by the caller/calling device.
For this feature to work, you must enable the desired DISA variant on the desired SIP trunk.
• A call lands on a DISA enabled Trunk.
• The system checks if a DISA variant is enabled on the trunk for the current time zone, that is, working
hours, break-hours and non-working hours.
• If a DISA variant is enabled on the trunk, the system processes the call according to the DISA variant
enabled on the trunk.
• If DISA with PIN Authentication - Multiple Calls is enabled,
• The system plays Welcome Greeting message to the caller.
• The caller must dial the DISA Login Code consisting of:
• the DISA Feature Access Code.
• the number of the extension the caller wants to access.
• the user password of the extension.
• On successful login, the system starts the DISA Idle State Timer (configurable; default: 20 seconds).
The system waits for the caller to go Off-hook
112
.
• 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.
• The system collects the digits dialed by the caller and then routes the call.
112. If the caller does not go Off-hook within this timer, the system releases the call.
