Agent AI SDK Reviews & Product Details

VaxVoIP Agent AI SDK is a Windows development toolkit that connects SIP servers and IP-PBX systems with OpenAI Realtime speech-to-speech models. It bridges live telephone-call audio to AI models so developers can build multilingual voice agents while focusing on conversation workflows, tools and automation. Use cases include AI receptionists, customer-service agents, spoken-information services, outbound voice automation and conversational IVR. The SDK handles the telephony-to-AI media connection and simplifies low-level integration. Working sample projects are available for Visual C# .NET, Visual Basic .NET and Delphi, alongside technical manuals and SIP-to-OpenAI integration guides. A fully functional 30-day trial is available. Commercial annual licenses are offered by concurrent-call capacity, with single-service and enterprise options. Licensing includes technical support, updates, new releases, maintenance, improvements and bug fixes during the license term. Product details: https://www.vaxvoip.com/agent-ai-sdk
