Hello everyone,
I need help to mod a table top telephone (no tel line but sim card instead).
I would like to take the hand free speaker signal to send it in a radio mixing desk.
It works but only for the tone. No voice...
I also would like to send a line level feed to the hand free (build in) microphone.
This is even trickier. I made a divider to attenuate (10kohms and 1kohms) and added a 10microfarads condenser to filter out the DC (needed for the electret mic).
The build in hand free speaker and mic are disconnected.
The goal is to use the hand free button to switch from hand set to the mixer and have the listener "on air".
Do you have any advice?
Thank you.

I have once repaired such a cable mod but the phone in question was an old Nokia used for radio soccer comments. It was working with an ordinary dynamic mic.
I believe on never phones You could tap into the earpiece. They usually have a mini TRRS jack for ear and mic. The inbuilt ear & mic isn't used, unless You can switch it via phone's software.
