Questions about Resilient Talk State
What is Resilient Talk State?
Resiliency gives your network the ability to handle calls and
provide voicemail service in the event of a 3300 ICP system
failure or a network-level failure. As a result, the 5550 IP
Console goes into Resilient Talk State. Resilient Talk State
maintains active calls in talk state when the failure occurs,
and defers "fail over" or re-registration until calls end. You
will know that the 5550 IP Console is in Resilient Talk State
based on the icons in the Console Status area.
What is "fail over"?
"Fail over" occurs when the 5550 IP Console is in the process
of connecting to a secondary or alternate 3300 ICP during
Resiliency. Note that call handling features such as Hold,
Transfer, Conference and Page are not available during "fail
over". Once "fail over" is complete, call handling features
become available once again.
What does in the Console Status area signify?
It signifies that the 5550 IP Console is connected to the
primary 3300 ICP; therefore, you are able to continue normal
operation.
What does in the Console Status area signify?
It signifies that the 5550 IP Console is connected to an
alternate or secondary 3300 ICP—not the original or primary
3300 ICP.
What does in the Console Status area signify?
It signifies that the 5550 IP Console is currently switching
between 3300 ICPs. The 5550 IP Console is in "fail over"
state.
What does in the Console Status area signify?
It signifies that repeated attempts of the 5550 IP Console to
connect to a primary or secondary 3300 ICP have failed. The
5550 IP Console will continue to attempt to connect to a 3300
ICP.
What do I do when the 5550 IP Console is in "fail over"
state?
Take a message or ask the caller to call back later (fail over
state usually lasts less than 30 seconds). Once the console
has connected to a 3300 ICP, will appear in the Console
Status area, and you will be able to resume normal
operation.
