VoIP has completely transformed the ways in which we stay in touch with one another. Gone are the days where you had to find a pay phone or purchase a calling card in order to make a phone call. Nowadays, VoIP providers enable people to simply dial their loved ones no matter where they are by plugging into their internet network.
VoIP or “Voice Over Internet Protocol” refers to a method of making telephone calls over the internet and is an alternative to using traditional phone service. VoIP is often referred to as Internet Telephony or IP Telephony.
Just like computers using the web, VoIP requires that phones have a direct internet connection. However, VoIP uses a different set of protocols to transmit voice than computers use to transmit data.
VoIP calls made through the internet must be able to reach non-VoIP numbers on the Public Telephone Network and vice versa. This function is provided by a VoIP service provider such as PCS. VoIP calls first go to PCS’s site and are then routed to the correct destination whether it is on the public telephone network or the internet.
