Wow, I've never heard of that happening. If anyone knows, I'd love to hear a technical explanation of how and why that could occur.
On Strowger electro-mechanical exchanges one of the nice features is that a random piece of the exchange handles each dialed call. This means the human intuitive approach of "Huh, that didn't work, I'll hang up and try again" actually had a pretty good chance of success if the problem is an electrical fault or something rather than you wrote the number down incorrectly.
I did have a morning once where every call I received was for a business in a Welsh village (I live in England) and the callers were as confused as I was that they'd reached a personal mobile phone instead. The problem resolved itself before it made me annoyed rather than confused.
Me, my friend and other friends of his called both companies to report the error multiple times. All we received was scorn and disbelief. We were told, repeatedly, that it simply couldn't happen. But it did, consistently.
It felt really silly when it got to the stage where I'd call my friend, someone else picked up and I'd go "Oh, hi, it's me again". One day, it just stopped happening.
This was circa 2006
Sadly I couldn't enjoy it, as I was running late for work and mistimed my jump onto a bus, breaking my ankle ...
