The Voice AI Platform for Business
Voice Nexus is an enhancement to the Voice Elements Cloud Platform that connects your phone numbers and WebRTC endpoints to OpenAI Realtime voice models — with full webhook control, tool integration, and call management.
Inbound AI Voice Handling
Connect DIDs and WebRTC sessions to realtime AI agents. Every call triggers your CallStart webhook, giving you per-call control over instructions, model selection, time limits, and billing context.
- ✓ 24/7 AI answering with natural conversation
- ✓ Per-call instructions via webhook
- ✓ Supports gpt-realtime and gpt-realtime-mini
Function & MCP Integration
During a live call, the AI can invoke tools connected to your scheduling system, CRM, databases, or any API. VNS brokers the request with full session context and feeds the result back into the conversation.
- ✓ Mid-conversation API calls
- ✓ MCP server support
- ✓ Flexible URL adapter patterns
Built-in Call Control Tools
Voice Nexus ships with built-in tools that require no server endpoint — end conversations gracefully, transfer calls (blind or attended), retrieve call metadata, and get the current time.
- ✓ vns_end_conversation
- ✓ vns_transfer_call (blind & attended)
- ✓ vns_get_call_info & vns_get_utc_datetime
