Matrix ETERNITY NE System Manual 813
• The caller gets logged into the Auto Login extension and gets dial tone of the outgoing trunks selected
for dialing ‘0’.
• 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 received before the end of the Warning Beeps, the system reloads the DISA
Inactivity Timer.
• After the external call is completed, that is, 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 SARVAM UCS again.
• In the variants of DISA, PIN Authentication and CLI Authentication, the caller can use all the features
allowed in the “Class of Service (CoS)” of the extension the caller is logged into.
• 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, SARVAM UCS will route the call by Built-In Auto Attendant logic, if Built-In Auto
Attendant is enabled. If DISA and Built-In Auto Attendant both are disabled, the incoming call will be
routed as per the Incoming Call Route logic. To know more, see “Auto Attendant”.
Feature Interaction:
• If both, Built-In Auto Attendant and DISA are enabled on the trunk, SARVAM UCS supports all types of
DISA.
• If both, VMS Auto Attendant and DISA are enabled on the trunk, SARVAM UCS supports only PIN
Authentication-Multiple Calls. To know how the VMS handles a DISA call, see “VMS DISA Login”

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” and “SIP Extensions” under Basic Settings for instructions on
configuring Class of Service for the different Extension types.
136. If no match is found for the CLI of the caller in the Table, the call will be routed as per the Incoming Call Route configured in SAR-
VAM UCS.
137. This feature is supported in Firmware Version V10R10 and later.
