Exiting Survivable Mode

Registration Behavior

When the Remote Oracle® Enterprise Session Border Controller exits Survivable Mode, it performs as follows for registrations:

  • It forwards all registration requests (new or refreshes) to the core data center (or headquarters) site. Note: All endpoints in the registration cache associated with that Registrar are invalidated.
  • "The "expires" value is no longer set to 30 seconds by default. It takes the corresponding registration-refresh value based on the Oracle® Enterprise Session Border Controller configuration.

    Note:

    When the Oracle® Enterprise Session Border Controller is in Normal Mode, it routes the incoming INVITEs to the registrar if the endpoint is part of the registration cache. If the endpoint is not part of the registration cache, the INVITEs are routed using the local policy if the local policy is configured on the Oracle® Enterprise Session Border Controller. Otherwise, a 404 Not Found is returned.

Call Processing Behavior

When the Remote Net-Net ESD exits Survivable Mode, it performs as follows for Call Processing:

  • It allows incoming sessions to be sent to the core data center (or headquarters) site for processing.
  • Existing sessions remain connected until a user ends the session.
