The doorbell and chime is connected to the network. From my app I can view the doorbell camera and voice recording. 

The issue is when I press the door bell it does not ring out.

When I try to reset it , I did not get the red /green flashing LED instead I got a voice prompt reset successful.

Even after many try it's still the same NO LED light up and door bell doesn't ring when pressed.

Anyone can help?
