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 dialing ‘0’. 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 SARVAM UCS from the remote
location.
WARNING! This feature allows access to system resources to remote users, and therefore has serious
implications for your system's security. There is a risk of fraudulent calls being made from your system, if a
third party comes to know the authentication PIN or the User Password of an extension number. The cost
of such fraudulent calls will have to be borne by the owner of SARVAM UCS.
To avoid unauthorized access, we recommend you to change the PIN regularly. Make sure, it is strong and
is provided only to those users who need to access the system using DISA.
How it works
For this feature to work, you must enable the desired DISA variant on the desired trunks: CO, Mobile, SIP.
• A call lands on a DISA enabled Trunk.
• The system checks if a DISA variant is enabled on the trunk for the current time, that is Day, Break or
Night.
• 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
133
.
• 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
134
.
• 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.
133. If no voice message is recorded, the system plays music-on-hold to the caller.
134. If the caller does not go Off-hook within this timer, the system releases the call.
