Communication Manager supports two survivability options: survivable core and survivable remote.
Survivable core server
With survivable core servers, Communication Manager operates during a network outage. A survivable core server provides survivability support to IP networks and Processor Ethernet for registering gateways and IP endpoints. This survivability option is available only for Communication Manager.
Survivable remote server
Survivable remote servers provide enhanced redundancy for Branch Gateway operating within networks. Survivable remote servers take over segments that lose connection from their primary call server and provide those segments with Communication Manager operation until the outage is resolved. A survivable remote server provides survivability support to IP and SIP telephones and Branch Gateway when the connection to the core server fails. This survivability option is available for Communication Manager and Session Manager.
For more information about survivability options, see Avaya Aura® Communication Manager Survivability Options.
Note:
If you have an S8300 server configured in embedded CM main, survivable remote, or embedded survivable remote configurations, migrate to Avaya Solutions Platform S8300.
