Hope you are not planning on connecting it to the real phone network...

Bar from the risk of high voltage (50v in the UK for example) it’s illegal in every country that I’ve looked at!

I also cannot see the picture.
It uses a GSM module, its just meant to look like a landline :)

Re: Phone hang-up sensor

I've spent a good amount of time looking online now but can't find a component that could act like the hang-up sensor (I'm not really sure what to call it) Traditionally called an on-hook/off-hook detector or switch. Presumably so named when phones had separate mouthpieces earpieces which were hung...

Phone hang-up sensor

Hi all, I'm trying to make a toy phone into a working phone like an older landline. I've spent a good amount of time looking online now but can't find a component that could act like the hang-up sensor (I'm not really sure what to call it), the thing circled in this picture. https://imgur.com/a/uBY9...
