Voice over Internet Protocol (VoIP), also known as Internet telephony, allows business owners to make calls via broadband Internet (and therefore their desktop computer) by turning sound into IP packets and then transferring this via the Internet. VoIP offers many benefits over calls that are made via the traditional telephone system and phone lines, which are outlined below. Keep in mind that VoIP telephone calls cannot be distinguished from traditional phone calls. VoIP is also easy to install and use.
