570 Matrix ETERNITY NE System Manual
• 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. 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 recieved before the end of the Warning Beeps, the system reloads the DISA
Inactivity Timer.
• After the external call is completed, i.e. the caller disconnects from the remote end or the other remote
called party has disconnected, the caller is logged out.
• To make another external call, the caller must call the DISA enabled trunk of ETERNITY NE again.
• In all the variants of DISA, the caller can use all the features allowed in the “Class of Service (COS)” of the
extension the caller is logged into (using PIN Authentication or CLI Authentication).
• DISA Inactivity Timer is not applicable for SIP and Mobile trunks.
• DISA calls in the SMDR report are marked as "O" in the remarks column. See “Station Message Detail
Recording–Report”.
• If DISA is disabled, ETERNITY NE will route the call by DID logic, if DID is enabled. If DISA and DID
both are disabled, the incoming call will be routed as per the Incoming Call Route logic. To know more,
see “Direct Inward Dialing (DID)”.
How to configure
To provide DISA to remote users you need to do the following configuration:
• Select the DISA variant for the Trunks in the Route Incoming Calls option on the trunk port parameters.
See “CO Trunks”, “Mobile Trunks”, and “SIP Trunks” under Basic Settings for instructions.
• Enable DISA in the“Class of Service (COS)” of the extensions which you want to allow callers to access
using DISA. See “SLT Extensions”, “DKP Extensions”, “SIP Extensions” under Basic Settings for
instructions on configuring Class of Service for the different Extension types.
• Change the User Password of the DISA extensions, if you selected DISA PIN Authentication-Multiple
Calls,If you selected DISA PIN Authentication-Multiple Calls on a trunk. The default User Password (1111)
will not work. See “User Password” and “System Security” for more information and instructions.
• Configure the related timers, DISA Idle State Timer and DISA Inactivity Timer, if required. See “System
Timers and Counts” for instructions.
• If you have selected the DISA CLI Authentication-Multiple Calls or CLI Authentication-One Call on a trunk,
you must configure the CLI Authentication Table.
