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: http://www.mills37.plus.com/Intercom.JPG

Inside each flat, there's a handset with a button to press to release
the door, thus: http://www.mills37.plus.com/Handset.JPG

Problem is that mine doesn't work properly, and I probably need to
replace the handset. The symptoms are these:

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

Theres a firm in London SRS doorentry it might be one of theirs if not
they may well know who made it..
