Hi
I copied this simple setup between 2 old analogue telephones: **broken link removed**
It works perfectly, however, it is very quiet when listening. This makes no real difference over 10 meters or 100.
Is there a simple way I can increase the volume perhaps by increase voltage or changing the resistor? I know our local telephone network actually runs on 12v - I am just nervous to try and break the phones.
I know this is very basic - if I am in he wrong forum pls point me to a better spot.
Tx
Thanks
Rod
