Note:
When the High Availability (HA) check box is selected, EMS server with HA mode replicates and preserves complete signaling state for all active calls and registration information of endpoints on the standby box. In the event that the active box fails, the standby box will be able to maintain the state of the active call such that all the features for that active call will be available. The EMS server with HA mode will maintain state information for calls on UDP, TCP, and TLS transport protocols.
Click Finish to save and exit.
Avaya SBC supports duplicate HA connection by using HA pair management addresses. With HA replication, if any of the M2 to M2 or M1 to M1 connections are down, the other connection continues uninterrupted.
