Opus is a lossy codec (RFC 6716), with excellent sound quality at extremely low bitrates, suitable for VoIP and low-latency streaming, and is the overall best solution for real-time voice scenarios.
VoIP numbers can be registered and used anywhere with broadband, and can even move across states or countries; users may continue using an old number after moving, leaving the registered address disconnected from the actual location.
The FCC requires VoIP providers to supply a "dispatchable location" on calls, but the proportion of users who manually update their address is very low, and automatic positioning is limited by the network environment, resulting in unreliable location information for a large number of VoIP emergency calls.
Google Voice is a VoIP-based communications service provided by Google that offers features such as calling, voicemail and SMS to eligible users.
Technologies such as VoIP, SIP, and WebRTC have already made calling over the network commonplace; internet telephony is not a new concept.
Platforms like Retell add a conversation orchestration layer on top of the ASR, LLM, and TTS modules, responsible for managing state machines, invoking external tools, handling interruption logic, and managing integration with PSTN or VoIP.
