Matrix PRASAR UCS System Manual 1203
VMS DISA Login
What’s this?
This feature allows the remote users to log into the DISA mode using the trunks on which the Voice Mail Auto
Attendant is enabled. The remote user can access and use the system's features and facilities using the DISA
enabled trunks.
The VMS supports DISA-PIN Authentication-Multiple Calls only. For detailed information on the types of DISA
Variants, see “Direct Inward System Access (DISA)”.
Using VMS DISA login, remote users can:
• call any extension.
• make external calls.
• use features and facilities of the system.
• configure features and facilities of the system and administer the system.
All these can be done as if being done from a local extension of the PRASAR UCS.
How it works
For this feature to work,
• you must have a free VMS channel available. Refer “License Management”.
• you must enable DISA-PIN Authentication-Multiple Calls (in the Trunk Feature Template) on the desired
SIP trunk.
• you must select Voice Mail Auto Attendant option (in the Trunk Feature Template) on the desired SIP
trunk.
• you must enable DISA in the “Class of Service (COS)” of the extension the caller is allowed to log into
(using PIN Authentication).
• you must change the default User Password (1111) of the extension the caller is allowed to log into.
This is how VMS DISA Login works:
• A call lands on a DISA enabled Trunk.
• The incoming call on the trunk is answered by the VMS Auto Attendant. By default, the VMS greets the
caller with the Greeting message followed by the Welcome Message: “Welcome! Please dial the extension
number or To dial by name press ‘6’,To leave a message press ‘7’, To access your Personal Mailbox press
‘8’, For further assistance press ‘9’, To disconnect the call press ‘#’.
• The caller must dial the DISA Login Code, 1079. The VMS checks if DISA-PIN Authentication-Multiple
Calls is enabled on the trunk for the current time zone, that is, working hours, break-hours and non-
working hours.
