VoIP (Voice over Internet Protocol) transmits voice communications over internet connections rather than traditional telephone circuits. It is the underlying technology for most modern business phone systems and voice AI platforms.
How does VoIP work?
VoIP converts analog voice signals into digital data packets transmitted over IP networks. Protocols like SIP handle call setup and signaling, while RTP carries the actual audio. VoIP can connect to traditional phone networks through gateways or operate entirely over the internet.
Why does VoIP matter for voice AI?
Voice AI platforms are inherently internet-based systems. VoIP provides the natural interface for connecting these systems to voice communications. It enables cloud deployment, geographic flexibility, easy scaling, and integration with other digital systems that would be difficult with traditional telephony.
VoIP in practice
A voice AI platform runs entirely in the cloud. Incoming calls arrive via VoIP from SIP trunk providers. The AI processes calls on cloud infrastructure, with audio traveling as data packets. Outbound calls route through VoIP to reach customers on any phone. The entire system operates without traditional telephone hardware.
