Re: GEC 1000 phone not working properly?
Could you measure off-hook line current at yours and your mum's? It might be easiest to do this inside the telephone by breaking either red or white wire and inserting a multimeter on milliamperes range. Or connect a 100 Ohm (or similar) resistor in line and measure the voltage across it, hence current.
With the original carbon mic, of course.
