Voice over IP (VoIP) & Data

Voice over IP (VoIP) is a technology that allows voice communication over the internet or private networks instead of traditional telephone lines. It converts voice signals into digital data packets and transmits them over an IP network.


How VoIP Works

1 Analog-to-Digital Conversion – Voice signals are converted into data packets.
2 Packet Transmission – Data packets are sent over an IP network (LAN, WAN, or the internet).
3 Digital-to-Analog Conversion – Packets are reassembled and converted back to audio.
4 Call Completion – The receiver hears the voice just like a regular call.
