Interesting case today. I had a call from customer saying they had a power cut and when the power was restored all their phones went into ‘Registering’ status.
I initially thought it could be a network issue from switches to CUCME gateway as the config was looking fine to me. I did a show ephone summary and found all of them in ‘Unregistered’ status. Nothing changed really, the config was all ok and these phones were all working fine few minutes before. So what has gone wrong?
I started going through the config if anything has changed but nothing changed. Then I did show telephony service and found below:

Did you guys see what was wrong?
Somehow the telephony service went into shutdown state. I did a no shut on telephony service and they all start registering.
