Auto attendant don't work after upgrade to 3.0.1 (Build: 4420)

My obi200, Auto attendant don't work after upgraded to 3.0.1 (Build: 4420) . When I call back my obi200 from the trusted caller, the obi200 ring right away and failed to call back after the caller hang up, please help!

Now I find out, it is working but not so stable, like, it might wait one minute to call back instead of a few seconds, or it ring the Obi200 in two minutes, I will keep watching.
