For more than two individuals. Using the old line, only two persons are allowed to talk. But with the use of VOIP voice communication, you can setup a meeting or conference with your whole team and you can also be able to communicate with them in real time. This is because VOIP compresses all data packets during the process of transmission. This then results in more data that the carrier can handle. This ensures VOIP service can handle more calls on just one access line.
Cheap user software and hardware. If you are an avid user of the internet and all you really want is a VOIP for your voice communication, the other hardware that you need to have aside from having an internet connection and a computer are speakers, microphone, and a sound card. These are are not very expensive so you don’t have to worry about cost.
