Black List IP Address - SIP Extensions
Black List IP Address allows you to restrict unauthorized users from accessing SARVAM UCS.
To use this feature, you must select the desired option in Black List SIP Extension IP Address:Port on multiple
Authentication Failure Attempts in the “Security Settings”. The SARVAM UCS blacklists the IP Address from
which an unauthorized attempt is made for registration. When any user attempts to register as a SIP Extension
using the false credentials— Authentication ID or Authentication Password and the authentication attempt fails for
10 times consecutively, SARVAM UCS blacklist the IP Address and port used for registration.
The blacklisted IP Address/es and ports are stored in the Black List IP Address - SIP Extensions table along with
the date and time. This activity will also be logged in the “System Activity Log”.
If you want to allow access of SARVAM UCS to such blacklisted IP Address, you must remove it from the Black
List IP Address - SIP Extensions table manually. If this IP Address is a Trusted IP Address, you can configure it
in the Trusted IP Address/es table to avoid further blacklisting. See “Security Settings” for details.
Black List IP Address table stores upto 50 entries. When the buffer is full, SARVAM UCS follows FIFO method to
store further entries. You cannot edit any entries in this table. However, if required, you may remove a entry from
this table.
To clear a entry from the Black List IP Address - SIP Extensions table,
• Login as System Engineer.
• Under Advanced Settings, click VoIP Configuration.
• Click Black List IP Address - SIP Extensions.
