The FreeSWITCH Dialer is a powerful tool that enables businesses to make outbound calls efficiently. It is built on the FreeSWITCH platform, which offers a modular architecture for customized solutions that can manage voice, video, and data on a single line, supporting communication between PRI and SIP lines. The dial plan is a decision tree that provides routing services to bridge call legs together, execute dial plan applications, and invoke custom scripts that you write. The mod_dialer module is a FreeSWITCH module that allows for making mass calls and sending them to an IVR, message, or whatever. It is designed to meet the needs of businesses that require making mass calls and when connected, send them to an IVR, message, or other destinations. The dialplan is not a scripting language and is not a single entity. Instead, it is a unique, independent method through which you can access information.
