Comparison
AurionAI vs Rezolve.ai
Rezolve.ai is the only other vendor offering voice AI for ITSM. While Rezolve.ai centers on Microsoft Teams, AurionAI takes a phone-first approach with SIP trunking, sub-second latency, and open MCP architecture.

Key Differences
1. Phone-First vs Teams-First
Rezolve.ai builds around Microsoft Teams. AurionAI starts with a real phone number (SIP trunk) connected to voice rooms. This works regardless of collaboration platform. The WebRTC widget extends voice to any browser, no Teams dependency required.
2. Measured Latency vs Unspecified Performance
AurionAI publishes its voice latency: under one second end-to-end. Rezolve.ai does not document VoiceIQ latency. Delays of 2-3 seconds feel unnatural. When evaluating voice AI, ask any vendor to demonstrate real-time latency with a live call.
3. Open Architecture vs Proprietary Platform
AurionAI uses MCP (Model Context Protocol) — an open standard with JSON-RPC 2.0. Adding a new ITSM provider means building a new MCP module, not modifying the core agent. Rezolve.ai uses proprietary connectors with broader ITSM coverage today but a closed architecture.
4. Transparent Pricing vs Contact Sales
AurionAI publishes all pricing. Free tier, EUR 199/mo Starter, EUR 499/mo Pro, with published add-ons and overage rates. Rezolve.ai requires contacting sales to learn costs. Published pricing means you can model costs before your first sales call.
Why Teams Switch to AurionAI
Need a real phone number AI answers
Your IT support line is a phone number. You need an AI that answers it, not one inside Teams.
Want to evaluate before talking to sales
Free tier with 25 minutes. Sign up, connect your ITSM, make a test call.
Not a Microsoft-centric shop
Google Workspace, mixed platforms, or frontline workers without Teams. AurionAI works with any phone.
Latency matters
Sub-second measured latency means conversations feel natural. Test it with a live call.
FAQ
Both offer voice AI for ITSM. What is the fundamental difference?
The voice channel. Rezolve.ai's VoiceIQ is built around Microsoft Teams. AurionAI is built around the telephone: a real phone number that AI answers via SIP trunk, plus a WebRTC browser widget. If your employees call a phone number for IT help, AurionAI is designed for that workflow.
Rezolve.ai supports more ITSM platforms. Is that a deal-breaker?
It depends on your ITSM. AurionAI supports Freshservice and HaloITSM with deep integration (31 tools). If you use one of these, you are fully covered. The open MCP architecture supports adding providers, but choose based on what is available now.
How does voice quality compare?
AurionAI uses neural TTS with 4 curated voices and per-language localization for 11 languages. STT uses advanced speech recognition with semantic turn detection. Rezolve.ai does not publicly document its STT/TTS providers. We recommend live voice demos from both vendors.
Can I use AurionAIAI alongside Rezolve.ai during evaluation?
Yes. AurionAI operates on its own phone number and WebRTC widget, independent of any Teams integration. Run AurionAI on a test SIP trunk while keeping Rezolve.ai active on Teams to compare.
Compare voice AI with a real call, not a slide deck.
Both AurionAI and Rezolve.ai offer voice AI for IT support. The best way to compare is to hear them. Start with AurionAIAI's free tier — 25 minutes on your own ITSM.
