Parameter account.X.sip_server.Y.failback_timeout
[1][2]
<MAC>.cfg
Description
It configures the timeout (in seconds) for the phone to retry to send requests to the primary server after
failing over to the current working server.
If you set the parameter to 0, the phone will not send requests to the primary server until a failover
event occurs with the current working server.
If you set the parameter between 1 and 59, the timeout will be 60 seconds.
Note: It works only if “account.X.sip_server.Y.failback_mode” is set to 3 (duration).
Permitted
Values
0, Integer from 60 to 65535
Default
3600
Parameter account.X.sip_server.Y.failback_subscribe.enable
[1][2]
<MAC>.cfg
Description
It enables or disables the phone to retry to re-subscribe after registering to the secondary server with
different IP addresses when encountering a failover.
Note: It works only if "account.X.sip_server.Y.failback_mode" is set to 1, 2 or 3.

Parameter account.X.outbound_proxy.Y.register_on_enable
[1][2]
<MAC>.cfg
Description
It enables or disables the phone to register to the secondary outbound proxy server before sending
requests to it when encountering a failover.
Permitted
Values
0-Disabled, the phone will not attempt to register to the secondary outbound proxy server, since the
phone assumes that the primary and secondary outbound proxy servers share registration inform-
ation. So the phone will directly send the requests to the secondary outbound proxy server.
1-Enabled, the phone will register to the secondary outbound proxy server first, and then send the
requests to it.
Default
-1, the phone will invoke “account.X.sip_server.Y.register_on_enable” to take effect.
Parameter account.X.outbound_proxy.Y.retry_counts
[1][2]
<MAC>.cfg
Description
It configures the retry times for the phone to resend requests when the outbound proxy server Y is
unavailable or there is no response from the outbound proxy server Y.
The phone moves to the next available outbound proxy server after three failed attempts.
Permitted
Values
Integer from 0 to 20
Default
-1, the phone will invoke “account.X.sip_server.Y.retry_counts” to take effect.
