How Does a VoIP Gateway Work?

A VoIP gateway helps connect old phone systems with internet-based calling. Here’s how it works:

Starting the Call: When you make a call, the gateway picks up the signal from a regular phone or an internet phone (VoIP).

Changing the Signal: If the call comes from a landline, the gateway changes the sound into digital data for the internet. If it’s from VoIP, it turns the digital data into sound for landlines.

Making It Smaller: The gateway shrinks the data into small packets so it moves quickly over the internet.

Sending the Call: The gateway decides if the call should go through the internet (VoIP) or a regular phone network (PSTN).

Receiving the Call: On the other end, the gateway changes the data back into sound so the person can hear you.
