What is FreeSWITCH?
FreeSWITCH is an open source telephony platform designed to power voice, video, and messaging applications. It acts as a core engine for many communication platforms, offering developers and businesses the ability to build scalable and flexible communication systems.
Key highlights of FreeSWITCH:
- Supports VoIP, PSTN, and WebRTC
- Handles thousands of concurrent calls
- Extensible through APIs and modules
- Runs on multiple operating systems, including Linux and Windows
Thanks to its flexibility and scalability, FreeSWITCH has become a preferred choice for building auto dialer systems, contact center solutions, and unified communication platforms.
What is an Auto Dialer and How Does It Work?
An auto dialer is a software application that automatically dials telephone numbers from a predefined list, eliminating the need for manual dialing. It connects answered calls to agents, plays recorded messages, or routes them to IVR menus.
Types of Auto Dialers:
- Preview Dialer – Allows agents to review customer information before the call.
- Progressive Dialer – Dials numbers one after another, connecting only when agents are available.
- Predictive Dialer – Uses algorithms to predict agent availability and maximize talk time.
Benefits of Auto Dialers:
- Increased agent productivity
- Reduced idle time
- Higher call volumes and efficiency
- Enhanced customer experience
When combined with the open source power of FreeSWITCH, an auto dialer becomes more affordable, scalable, and customizable compared to traditional solutions.
