What abbreviation stands for a protocol that carries voice communications over IP networks?

VoIP VPN GSM LAN

Correct Answer:

VoIP

Explanation:

Voice over IP, or VoIP, is the way to send voice as digital packets over IP networks such as the Internet. It uses signaling protocols like SIP to set up calls and transport protocols like RTP to carry the actual audio data. This distinguishes it from VPN, which creates secure connections; GSM, which is a mobile cellular standard; and LAN, which describes a local area network. So VoIP is the abbreviation that represents voice communications over IP networks.
