SignalWire's RELAY Auto Dialer is an intelligent outbound calling solution that automatically dials phone numbers from a list without manual prompting. It uses advanced speech detection, answering machine detection (AMD), and word count technology to maximize contact rates and improve lead conversion.
ASR detects whether a real person has answered the phone. The faster a human voice is identified, the faster that person can be connected to a live agent — reducing dead air, improving caller experience, and increasing the value of each call.
Yes. SignalWire's auto dialer is designed for easy integration with existing CRM software, enabling your outbound call workflows to work in sync with your customer data and sales processes.
RELAY uses persistent, asynchronous WebSocket connections that enable real-time call control — ideal for auto dialers that need to react instantly to call events. Traditional synchronous REST APIs require polling and introduce latency that is unsuitable for high-volume, time-sensitive outbound calling.
