Hi,

The image shows an open phone.
Have you not accidentally caused a short circuit somewhere?
Sorry, I can't help you.
Kind regards,

Please tell me, what did you decide to open the phone... a flashing led?

When you lift the handset, you hear a busy tone... Is the phone registered and/or do you receive calls?
Kind regards,
Frank.

What about registration?
Is the phone registered to a VoIP Provider or PBX?
Can you receive calls?
Do the phone ring on incoming calls?
Kind regards,
Frank.

Please use the credentials you got from your VoIP Provider or PBX and setup phone account[x] so the phone register successful.
The Power Led will stop flashing and you can make and receive calls.

Frank.
