Source notes citing this source

• Cisco advises against enabling Record-Route on the SIP proxy server in a CVP deployment because it makes the proxy a single point of failure. in context
• When a CVP Call Server's SIP Service fails, the contact center SIP proxy sends new incoming calls to an alternate Unified CVP Call Server. in context
• Failure of a CVP Reporting Server has no impact on call survivability. in context
• CVP Server Groups are a dynamic routing feature that speeds call-control failover by removing delays when a destination is down. in context
• In CVP designs the contact center SIP proxy provides weighted load balancing, redundancy and centralised dial-plan configuration. in context
• If the CVP SIP Service fails after a caller has been transferred, the call usually continues, but the SIP Service cannot transfer that call again. in context
• If a Cisco VVB fails, the ingress gateway's survivability features by default route calls in progress to an alternate location, and new incoming calls find an alternate VVB. in context
• When a CVP VXML Server fails, new calls go transparently to an alternate VXML Server, but recovering calls already in progress requires scripting techniques in the application. in context
