CSS Redundancy
CSS supports several types of failover mechanisms. The Virtual IP redundancy mechanism will allow
for a rapid failover from a defined Master CSS to it’s backup using VRRP. This failover takes less than
3 seconds and may or may not additionally incorporate the use of ASR. Customer Voice Portal
transactions to servers do not require a stateful connection to the gateway. If the CSS fails during a
prompt, the vxml documents that drive Customer Voice Portal will retry and re-stream the prompt from
the new CSS access.

For this reason, general VIP redundancy is implemented. The sample below shows the redundant section
