Businesses are no longer tied to a specific telephone area code because of their physical location. The advent of internet telephony makes it possible to pick up calls anywhere in the world as though you were actually located in the area denoted by your telephone number.
VoIP services channel calls over the internet at little to no cost, so businesses can give the impression of a high-value location through their telephone number while operating out of offices in a much cheaper area.

DID stands for direct inward dialing. In some areas of the world, the system is known as direct dial-in (DDI). The term refers to the idea that numbers are not tied to a geographic location. Instead, service providers route calls through a private branch exchange (PBX) to the true location of the number’s owner.
The PBX explains how the DID system got its name. Historically, a business would have one telephone number for each office. The office would have a switchboard that received all incoming calls, and the caller would ask the switchboard operator to be put through to a specific person or department in the company. The operator would then look up the extension number of that person and transfer the call.
When PBXs replaced switchboards, it became possible to automate the call transfer process. The caller would wait for a message and then enter the extension number to get through to the right person.
The fact that telephone directories didn’t publish the list of extensions in each building was an issue with this system since anyone making a general inquiry wouldn’t know the right telephone extension number. In these cases, people still had to call into the reception desk in order to ask to be put through to the right person.
