Failover Server Redundancy Configuration
The following table lists the parameters you can use to configure failover server redundancy.
Parameter account.X.sip_server.Y.register_on_enable
[1][2]
<MAC>.cfg
Description
It enables or disables the phone to send registration requests to the secondary server when encoun-
tering a failover.
Permitted
Values
0-Disabled, the phone will not attempt to register to the secondary server, since the phone assumes
that the primary and secondary servers share registration information. So the phone will directly send
the requests to the secondary server.
1-Enabled, the phone will register to the secondary server first, and then send the requests to it.
