More detailed information on standby gateways
One or multiple standby HG 3500 IP line gateways can be defined in the
system that will take over in case any of the installed line gateways fails.
This concept is very efficient and cost effective because a single gateway can
protect multiple gateways against failure. However, a single gateway cannot
protect against multiple gateways failing simultaneously, which is highly
unlikely.
In case of a failure, the system will reprogram a standby gateway with the
parameters of the failed gateway which will enable the IP clients to re-login
and resume standard operation.
IP phones will automatically register with the activated standby gateway and
no administrative action is required. Note that users keep the same features
and extensions while operating off the standby gateway.
