What is SIP
Sip means Sessions Initiations Protocol. When you want to talk to your friend, you would need to dial to your friend. First you and your friend need something that looks like a dialer to appear on your computer screen.
This software is called the softphone.
Then both of you need a SIP number so that you know what number to dial to. It is like a telephone number.
Anyone can issue a SIP number. If ABC company issues the SIP number, then only ABC company can make the connection for you. Although the calls are free so long as you remember to pay your internet subscription, ABC company may charge you a small monthly Connection fee or Access fee.
