From software 2.13 we have implemented the SIP account Failover feature.

When enabled, the device will use the next SIP account when the First SIP account Registration Failed.


Web-interface

Go to: Settings - Telephony - Connections - SIP accounts failover.

When this option is enabled, the device will switch to the next available SIP account when the first SIP account Registration failed.


Parameter nameDescription
SIP.Accounts.Failover

0 = Do not use failover (default)
1 = Use failover

Example: <param name="SIP.Accounts.Failover" value="1"/>
