VaxVoIP SIP AI Voice Agent SDK

VaxVoIP Agent AI SDK helps developers and businesses build multilingual AI voice agents for live telephone calls. It solves a common integration challenge: connecting existing SIP servers and IP-PBX systems to conversational AI without developing the low-level audio bridge and managing complex AI communication protocols from scratch. How it works: A caller connects through your SIP server or IP-PBX. The SDK bridges the live call audio to OpenAI Realtime, where speech-to-speech models process the conversation and generate spoken responses. Those responses are delivered back to the caller, enabling natural, two-way voice conversations in multiple languages. Key features: • SIP server and IP-PBX connectivity for existing telephony environments. • Integration with OpenAI Realtime speech-to-speech models. • Live SIP audio processing for interactive telephone conversations. • Multilingual voice interaction for callers who speak different languages. • A gateway architecture that simplifies communication between telephony systems and AI. • Working sample projects in C# .NET, Visual Basic .NET, and Delphi. • Technical documentation covering configuration, SDK functions, events, and call workflows. • A fully functional 30-day Windows trial for evaluation. What makes it different: VaxVoIP Agent AI SDK focuses specifically on connecting SIP telephony with real-time AI voice models. Developers can use their existing telephone infrastructure while focusing development on conversation design, application logic, tools, and business automation. The included sample projects provide a practical starting point for evaluating and implementing the integration. Common use cases: • AI receptionists that interact with incoming callers. • Customer service agents for multilingual conversations. • Automated information agents that deliver spoken information over the phone. • Conversational IVR systems that let callers explain what they need naturally. • Outbound AI voice applications built around SIP call flows. Expected benefits: The SDK can reduce the amount of custom integration work needed to add AI voice capabilities to a SIP-based application. It gives teams a foundation for prototyping voice agents, extending existing PBX services, and developing commercial telephone automation. The SDK runs on Windows and is available through annual commercial licensing with options for different concurrent-call capacities. Annual licensing includes technical support, updates, new releases, and ongoing maintenance.
