SIP Proxy-based HA Workflow

The workflow of a primary-to-backup switchover proceeds as follows:

  1. The primary SIP Server fails, disconnects, or a switchover is initiated manually.
  2. SIP Proxy detects the primary SIP Server failure (or disconnection) if one of the following occurs:
    • The primary SIP Server stops responding to OPTIONS messages.
    • SIP Proxy receives a SIP request from the backup SIP Server.
  3. SIP Proxy proxies all SIP traffic to the backup SIP Server which now runs in primary mode.

Note: Multiple independent Active-Active RM pairs may be deployed, although this configuration is not depicted here.
