VaxVoIP Agent AI SDK
SIP-to-OpenAI Realtime gateway SDK for building voice agents on SIP servers and IP-PBX systems
VaxVoIP Agent AI SDK bridges a SIP server or IP-PBX to OpenAI Realtime speech-to-speech models, so developers can build voice agents for live phone calls without handling the SIP media layer themselves. It is a Windows SDK with sample projects in C# .NET, VB.NET and Delphi. The vendor lists AI receptionists, customer service agents, outbound calling and smart IVR as use cases.
Licences are annual and sized by concurrent calls, from $1,480/year for 10 calls up to $16,860/year for an enterprise licence. A 30-day trial is available.
Pricing: Annual licences
