What Is Automatic Number Identification (ANI)?
#ANI stands for Automatic Number Identification, a system that telephone companies use to determine the phone number of the person calling them. It first sends a signal to the switching system of the phone company, which then looks up the caller's phone number in a database and transmits that information back to the receiving end of the call. Let's imagine you're the one getting phone calls, and you're curious about the identity of the person phoning you. You could make an educated guess based on the caller's voice or make an effort to remember if you gave out your number to anyone in the recent past; however, with ANI, you don't need to make educated guesses or remember who you gave your number to. The switching system of the phone company completes the task for you and provides you with the caller's telephone number in real-time. Now, let's delve into some of the nitty-gritty details. ANI is frequently used in conjunction with another system known as Automatic Location Identification, or ALI, which is designed to determine the location of the person making the phone call. The combination of ANI and ALI can reveal a lot of information about the caller. This information can include the caller's phone number, location, and even name (if it is listed in the database maintained by the phone provider). ANI is also occasionally used in conjunction with #CallerID, a system that displays the caller's phone number on the phone that is on the receiving end of the call. Before picking up the phone, the person on the receiving end can check to see who is calling by looking at their number. In conclusion, the Automatic Number Identification (ANI) system is a way for phone companies to find out the phone number of the person calling. It functions by first sending a signal to the switching system of the phone company, which then looks up the caller's phone number in a database and transmits that information back to the receiving end of the call. It is frequently used in conjunction with ALI and CallerID, as it can reveal a wealth of information about the person calling.
