"Before equal considering withdrawal of the copper-based PSTN stock, the reliability and quality publicize with the alternatives needs to be addressed. Both cavitied and VOIP systems expect electrical power at both the transmitting and receiving end. When this fails, the force also fails.
By oppositeness, the PSTN is fashioned so that the grouping is powered by CO equipment, which tends to be massively tautological. If the electrical grid fails, the PSTN should fiat up for weeks, without requiring anything on the consumer sidelong. The like cannot be said around today's alternatives.
"Also, melody attribute is a brobdingnagian printing. Both pitted and VOIP systems present latency and shrinking, neither of which is delectable. It is fair said that my Midwestern Galvanising 302 desk set from 1938 has finer unbroken calibre than a modern multicellular ring or VOIP ring. Also, home-type VOIP services tend to not support QoS [nb "caliber of pairing"] routing, and show can humiliate based upon meshing traffic
