CallCenter.js VoIP Telephony
AI-powered VoIP agent system built by Torben Gerkensmeyer that enables making phone calls with OpenAI's real-time voice API through SIP-based telephony infrastructure. The implementation features native G.722 wideband audio codec support for high-quality voice transmission, comprehensive SIP provider profiles for Fritz!Box, Asterisk, Cisco CUCM, and 3CX systems, and intelligent call brief processing that converts simple text descriptions into detailed AI agent instructions using a meta-prompt system. Built with TypeScript and Node.js native addons, it includes advanced features like automatic transport fallback, connection management with provider-specific error handling, audio resampling between different sample rates, and performance monitoring, making it valuable for businesses automating phone-based customer service, appointment booking systems, or any scenario requiring AI agents to conduct natural voice conversations over traditional phone networks.
