Sorry to be dense, but what's a "phone call" ? At 08:12 PM 10/9/2014, James Propp wrote:
Sorry to veer a bit far from math, but some of you are phone-network folks, so maybe you can tell me: What do you call it when person A calls person B and after a few rings get shunted into voice-mail, without person B's phone ever ringing? (It's not a "dropped call"; that means something different.)
My wife and I have this kind of experience many times, and have sometimes reproduced it with us and our two phones all in the same room or the same car. It's not a device-dependent effect; all cellphone-types seem to be equally susceptible. It's a network thing. It's the phone company saying "Hey, we could be honest and admit that the network is too busy for us to give you a connection right now, but then you'd probably consider switching to one of our competitors, so we'll just pretend that your party isn't answering." (Back in the days when AT&T had a monopoly, at least they were honest. As Lily Tomlin put it: "We're the phone company. We don't care. We don't have to.")
Anyway, I'm considering switching carriers, except what if the competitors' networks are even worse? What I need are comparative statistics on calls that are never completed because of network issues. But before I can get those numbers, I'll need to know what they're called!
Can anyone supply the relevant phone jargon?
Thanks,
