Comment Collect Calls (Score 3, Informative) 101
Land lines can accept Collect Calls. Where the person calling you might be stuck in a situation where they are far away, and can't afford to pay for a call (such as a pay phone, stuck in a prison, in jail for some reason). They can ask the operator to reverse the charges, so that you, the one receiving the call, can talk to that person.
VOIP phones don't have the billing infrastructure and laws/regulations that require they have this ability. As a result, loss of land lines means less and less ability for a family member to be able to reach you in an unexpectedly harsh emergency.
The only reason I still have a land line is because this happened to me. A family member ended up in jail, and the only way that they were able to call and let me know was because I had a land line. If I hadn't had one, I suppose I would have found out... eventually? Somehow? It's hard to say.
I really feel like we're losing something, and not many people are giving serious thought to this particular service, because it's so rarely used, and hard to predict what conditions would have to happen for it to be useful.
