XML Configuration

<dns_fallback_time perm="PERMISSIONFLAGS">VALIDVALUE</dns_fallback_time>

Description

Specifies an optional fallback time from secondary dns server to primary dns server.

Default dns request failover behavior is to always query the server with the fastest response time. The value for this setting is set to "65535".

If you want to always query the primary dns server first, specify a value of "0" here. Please note that if the primary server is really down, this also will delay your phone reactions up to 3 seconds for each new dns request during the server downtime.

Or you can switch back after a defined time from secondary to primary server again (this will reduce the load and give your dns administrator some time to fix it). To do so please specify the given time value in seconds here.

Valid Values

S
0, 65535 or any positiv integer in seconds

Default Value

65535 (query fastest server)
