Redundancy Notification Call
What’s this?
When the active server fails, the standby server takes over the control and becomes active. This process of
restoring the functionality of the server by transferring the active operation to the standby server is known as
redundancy. To know more, see “Redundancy”.
As redundancy is an important event, the intimation of the same can be provided to the concerned entities in an
organization via an auto-generated notification call, known as Redundancy Notification Call.
This redundancy notification call is generated by the server and sent to the desired landing destination/s, after the
redundancy process is completed.
You can either select a dedicated SIP extension or a routing group as the landing destination for the redundancy
notification call.
You can also define different landing destinations for each time zone, that is Working Hours (WH), Break Hours
(BH) and Non-working Hours (NH) as per your requirement.
How it works
• After the redundancy process is completed, the extension configured to receive the redundancy
notification call rings
123
, displaying the message “Redundancy Notification Call” on the LCD screen.
• When the extension user answers the redundancy notification call, s/he is played a piece of music or a
voice message as uploaded in MoH management. To know more, refer to “MoH Management”.
• The extension user can now acknowledge the redundancy notification call. The acknowledged redundancy
notification call is logged in the “System Activity Log” as well as “Simple Network Management Protocol
(SNMP)” with the details of the extension that acknowledged the call.
• If the extension configured to receive the redundancy notification call is busy, then the system will place
the notification call only after the extension becomes idle.
• If the extension user does not answer or reject or answer but does not acknowledge the redundancy
notification call till the expiry of the Ring Back Tone Timer, then the system makes one more attempt after
an interval of 10 minutes and place the notification call on the landing destination again. Now, if the
redundancy notification call is not acknowledged, then the notification call is logged in the “System Activity
Log” as well as “Simple Network Management Protocol (SNMP)”.
123. The extension rings for the duration of the Ring Back Tone Timer (configurable, default:45 minutes). See “System Timers and
Counts”.
