Why Use twiml-voice-agents

Configuring an agent is fairly simple and easy.

Limitations

The twiml-voice-agents package is limited by the fact that it supports half-duplex communication.

Half-duplex means that both a caller and the agent can speak, but only one at a time. The caller can interrupt the agent (technical name for this is barge-in). However, due to the nature of TwiML apps, there is a time when caller input will be lost. That period begins when Twilio detects an end-of-turn for the caller and awaits a response from your twiml-voice-agents server.
