Businesses are no longer tied to specific telephone area codes because of their geographic location. The advent of Internet telephony has made it possible to receive calls anywhere in the world as if you were physically located in the area indicated by the phone number.

Internet phone services make calls over the Internet at low or no cost, so a business can give the impression of a high-value location through its phone number while conducting armenia phone number list business outside the office in a much less expensive area.

The reallocation of call destinations opens up many opportunities. These can be achieved through DID numbers.

DID stands for Direct Inward Dial. In some parts of the world, the system is called Direct Dial In (DDI). The term refers to the fact that the number is not tied to a geographic location. Instead, the service provider goes through a private branch exchange (PBX) to the real location of the number owner.

PBX explains the name of DID systems. Historically, a company had one phone number for each office. The office would have a switchboard that answered all incoming calls, and callers would ask the switchboard operator to be transferred to a specific person or department in the company. The operator would then look up that person's extension number and transfer the call.
