Limitations after a successful failover
Failover to a Session Manager
instance
After a phone successfully fails over to a secondary Session Manager, all features and
functionality work properly for new calls. However, there are limitations to modify a preserved call.
Failover to a Branch Session Manager
After a phone successfully fails over to Branch Session Manager, the value of the parameter
FAILBACK_POLICY changes to Admin. In this case, you must go to the System Manager and
manually re-register the phone with Session Manager.
Note:
Administration of Session Manager and Branch Session Manager nodes are explicitly required
in the System Manager user record.
