Voice Over Internet Protocol (VoIP) is a technology that enables the transmission of voice and multimedia content over Internet Protocol (IP) networks like the internet.
It is the fundamental protocol for services like video calls, voice calls, and video conferencing.
VoIP converts audio and video signals into digital data packets, which are transmitted over the internet.
- Video Over Internet Protocol and Video Audio Over Internet Protocol are not standard terms or protocols.
- Internet Protocol (IP) is the underlying protocol for routing data but does not specifically handle real-time audio/video communication alone.
Therefore, the correct protocol that enables video calls is VoIP.
