What is a VoIP gateway?
In the past, it was common to use telephone lines for telephones in both homes and businesses, and many people still use them today. On the other hand, recently, a call technology using Internet lines called "VoIP" has emerged and is spreading throughout the world. However, calls over these phone lines are not compatible with calls over the internet. A VoIP gateway is the machine that connects the telephone network and the Internet network so that these calls can be made to each other.
