In the 1970s and early 1980s, the cost of making a phone call decreased and more business communication was done by phone. As corporations grew and labor rates increased, the ratio of secretaries to employees decreased. The initial solution to the phone communication problem for businesses was the “message center.” A message center or “message desk” was a centralized, manual answering service inside a company manned by a few people answering everyone’s phones. Extensions that were busy or rang “no answer” would forward to the message center onto a device called a “call director”. The call director had a button for each extension in the company which would flash when that person’s extension forwarded to the message center. A little label next to the button told the operator whose extension it was.
As wireless communication technologies increased in the late 1980s, the Pager service providers created a subscription service offered in a variety of plans and options to meet the needs of a subscriber and the type of device used. In general, all pagers are given unique telephone numbers so that callers could dial in and send a numeric message, such as their callback number or a numerically coded special message, such as room numbers to report to, etc.[1] However, alphanumeric pagers could only receive text messages when the message sender had installed software on their PC to dial in to the publicly accessible modems operated by the paging[2] service provider to then transmit their message over-the-air through the network of radio towers.
