My holiday flat has an intercom system which is supposed to enable me to communicate with callers and let them in if appropriate.
Outside the main door, there's a box with microphone and speaker, and a button for each flat, thus:
A caller presses my button on the outside intercom, and a buzzer sounds in the flat - ok.
I pick up the handset and speak, but the caller can't hear me. [If the caller speaks, I can hear them - but they're not likely to unless they hear me first!]
If I press the button on my handset, the door unlocks - but the caller can't hear my instruction to push the door!
I can't find any ID (make/model, etc.) on the handset or outside intercom and wondered whether any of you might recognise it. I'd like to replace the handset to see whether that fixes the problem.
TIA
