By using the Failback Policy feature, you can determine how the SIP phones failback to normal operation after connectivity to their primary Session Manager is restored. This policy only applies to failback between core Session Managers. You can configure the Failback Policy field on the ElementsSession ManagerGlobal Settings page of the System Manager web console.
Note:
In the case of Branch Session Manager, the failback policy setting does not apply. Failback from Branch Session Manager is always initiated in coordination with the failback policy of the collocated SRS.
