Simple: it's too expensive.
Keep this in mind when trading in your POTS service for VoIP service over the internet. Discounting the local loop which is often the same in both cases, POTS is extremely reliable while VoIP over the public internet, well, isn't. But apparently people that switch to VoIP don't mind the reduced likelihood of being able to make calls during the next large scale emergency.
Yes! I agree 100%. The key words in that above statement were "cheap commoditized." The reason satellite phones work in big disaster areas (other than the fact that the entire infrastructure in the affected area is comprised of a solar powered satellite and a subscriber's hand set with a remote base station(s) somewhere else in the world) is simple; not everyone and their cousin has one to use. Why? Because they're too expensive! Cell phones have trained the public in to accepting lower levels of phone service. Low cost equals high market adaptation, and in most cases, lower QoS. -Jerry
