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


no short circuit
the led keep flashing before i open phone

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?

i decide to open the phone cuz its need cleaning from dust

when i lift the handset i hear a busy tone
and when press at any key not make any tone

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

Best regards,
Frank.
