SIP Server HA Workflows

These topics describe workflows for SIP Server HA Architectures:

• IP Address Takeover
• Windows NLB Cluster
• Using SIP Proxy

The workflows provide a step-by-step account of events that occur during a manual switchover, during a primary SIP Server failure, and during a primary SIP Server disconnection.

For configuration and deployment information that are referred to in the SIP Server HA workflows, see SIP Server HA Deployment.
