How do I get sound working again please. The phone rings but no sound in either direction. WhatsApp calls fine.

Can you clarify what you mean by "fibre" phone? Is it a VoIP service, so connected directly to a Hub, or via Grandstream adapter?

HI @Jehu4419

Try rebooting the Grandstream DVA unit.

I have tried rebooting everything without success. The phone light on the Grandstream is blinking. According to the instructions this is supposed to mean a call is in progress.

Hi @Jehu4419

I realise that this may be difficult to access, but is it fast or slow flashing?

Fast Flashing - Phone off hook or user busy
Slow flashing - Voicemail waiting

What is the state of the Internet light?

The phone light flashes on for 2 seconds then off for less than 1 seconds. The other two lights are on continuously. The ethernet light on the wall box flashes irregularly. Thanks for helping.

In that case, @Jehu4419 I would suggest you contact the Full Fibre Helpdesk on the number quoted earlier; perhaps the Grandstream is faulty.
