Show HN: Open-source phone calling infra for AI agents (github.com)

AgentLine has launched an open-source telephony API designed specifically for AI agents, allowing them to make and receive calls and handle SMS without requiring telecom expertise. This innovative platform offers a simple REST API coupled with a built-in Model Context Protocol (MCP) server, enabling integration with various AI models, including Claude and Cursor. With features such as speech-to-text (Deepgram), text-to-speech (Cartesia), and seamless transcription storage, AgentLine strives to make voice communication easily accessible for developers. The significance of AgentLine lies in its democratization of telephony capabilities for AI applications, drastically reducing setup time and complexity compared to existing solutions like Twilio. The inclusion of a comprehensive voice pipeline, multi-provider support, and user-friendly installation process positions it as a game-changer for developers looking to enhance user interactions through voice. The platform is built with modern technologies, allowing easy deployment in environments like AWS, GCP, and Docker. This move could foster a new wave of innovative AI applications that engage users via voice, elevating the landscape of AI/ML development.
