Well modern ones work entirely in software – initially on mainframes – so creating a number alias is likely updating a database table. How did old ones like for rotary phones work? They had this big machine which would take inputs and then route them to a bunch of output wires. How do you make an alias? Connect the 112 output to the 911 input. How much does an insulated wire cost? Max like five dollars.
This isn't expensive.
Those claiming it is really need to tell us why.
"You truly live in a wonderful nation, Ambassador, where all telecommunications can be run through a single telephone exchange, and where accounting for a shared number is as simple as tying one wire to another."
