In some rare cases the SIP registration will not restore when the SIP server or SBC is temporarily unavailable.
In software 2.57.1 we have added a mechanisme to monitor the SIP-registration behaviour. The monitor is capable of detecting when the SIP-registration is not succeeding as expected.

By default the monitor is on and will start taking action when the system is still in this state after 30 minutes have passed.
When the monitor has detected this state and the set time has passed, it will start one of the options to restore the SIP-registration.

There are 2 options to restore the SIP-registration when in this state:

• Restart (TLS) transport (default)
• Restart SIP application
