I'm seriously considering a switch from AT&T land line service. Since I have fiber service, even though the dial tone still comes from the central office, it connects through the fiber gateway that provides my internet access, and as a result when the power goes out, so does my land line.
I have maintained a land line for its nearly 100% reliability, but with fiber service, that's no longer the case. The copper facilities in my neighborhood are ancient and AT&T has given up on them. I'm sure there are grandfathered copper land lines near me, but AT&T won't provision new land line service over copper, or at least that's what they keep telling me. At the very least I'd have to quit AT&T for internet and right now I'm getting a great deal for 100+ mbps at $49/month.
Given the gateway situation, it makes no sense to pay for supposedly traditional land line service when it would fail just like VOIP in a power outage. I've stopped using the land line for long distance. One long distance call that costs less than 50 cents will generate $12 in taxes and fees. No wonder people are abandoning their land lines.
I'll have to investigate which VOIP services will support rotary dialing. I love using my indestructible vintage Western Electric telephones and don't want to give that up.
