1. APPLICATION NOTE – 21
Product: SETU ATA211, SETU ATA211G, SETU VGFX
Feature: PIN Authentication
Incoming calls on SETU ATA211, ATA211G and SETU VGFX can be authenticated before the call lands on
it. Up to 100 users in the adaptors and 500 users in SETU VGFX can be provided with user IDs and
passwords for such authentication. The caller has to first prove his authentication. Once authenticated,
the caller can then place call to any of the extension or place an outgoing call using the GSM, SIP or FXO
trunk line. Such verification avoids the possibility of malicious calls and misuse of system resources. The
feature can be selectively enabled on all or a set of trunks. This sort of authentication is called PIN
Authentication.
How it Works?
Programing the PIN Authentication Table in the Web GUI, a user with PIN 121 places a calls the SIP trunk
1 of SETU ATA.
If the Authentication Type under the SIP Port parameters is programmed as “PIN Authentication”, the
caller will be prompted (by a routing tone) to enter a PIN.
When a caller enters the correct PIN, the call can either be routed to extension port or else the caller can
be given dial tone to place a call using the trunk lines. A dedicated trunk line can be given to the caller or
the call can be established using the routing logics in the Dial Plan.
Benefit:
Selectively Grant Calling Rights to Users
Avoid Malicious Calls, Allow Calls only from Certified Users (Users with PIN)
