Phone isn't dialling from caller but is ringing other end, but when answered, can't hear caller

As above, caller dials number but nothing happening, however the phone does ring the other end, and when answered, cannot hear the caller. This is an intermittent problem, but can't work out why this is happening.

Hi Michelle. Which Doro phone are you using? When making a call, can you press the volume up key? I'm thinking maybe you accidentally pressed volume down and muted the call volume.
