Why was I sometimes able to hear my neighbor’s phone calls on my phone back in the day

462 viewsEngineeringOther

I was a teenager in the 90s, so I was on the phone constantly. Sometimes I could hear someone else’s phone call on my phone while I was talking to someone.
Sometimes they could hear it too, sometimes not. And I do recall this happening to my friends sometimes as well.
And how often could someone else hear my conversation?

Back in the analogue days, you could get “Crosstalk” induced by wires being too Close together in the old telephone systems.

The old red/green/yellow/black inside wiring cable had basically no or very random twists, and no insulation making it prone to crosstalk.
