Your AI Agent Can Make Real Phone Calls — Without Touching RTP or SIP

If you're building AI agents that need to communicate with humans, you've probably hit the same wall: voice is hard. Not the AI part. The telephony part. RTP, SIP, DTMF, codecs, NAT traversal — this is a 40-year-old stack that was not designed for agents. Most developers end up either avoiding voice entirely, or spending weeks fighting infrastructure before writing a single line of agent logic. There's a better path. The Core Problem: Agents Shouldn't Handle Audio A typical DIY voice bot pipeline: Receive raw RTP audio from the caller Run STT to get a transcript Send the transcript to your LLM Run TTS on the response Stream audio back over RTP Every step has latency, codec issues, and infrastructure concerns. And none of it is your actual product. Media Offloading: Let VoIPBin Handle Audio VoIPBin uses Media Offloading. Your AI agent only ever sees text. VoIPBin handles RTP, STT, and TTS. Caller → VoIPBin (RTP/STT) → Your Agent (text only) → VoIPBin (TTS/RTP) → Caller Getting Started 1
