FAQ
You can use Quantrova API’s or AI Assistant Builder, a no-code interface where you define behavior with natural-language instructions and greetings in the Mission Control Portal. You can test agents via the in-browser simulator and deploy them in minutes.
Yes. Quantrova supports flexible model and provider selection, so teams can connect preferred tools and switch configurations as their needs change.
Quantrova is built on a dedicated real-time communication architecture with optimized compute, routing, and voice infrastructure designed for low-latency Voice AI.
Quantrova has 2 ways to decrease latency
- Co-location of GPU clusters and telephony PoPs – reduces RTT to under 200ms
Voice data is routed through optimized infrastructure designed to reduce unnecessary hops and improve real-time audio performance.
Support spans 29–30+ languages.
Through built-in tools like dynamic variables, call transfers, memory, calendar integrations, CRM updates, and MCP Servers for seamless handoffs and backend workflows.
Yes! teams can upload files or URLs via the Quantrova portal to refresh FAQs, policies, and knowledge bases in real time, no coding required.
Noise suppression is enabled by default, ensuring cleaner, more natural audio without manual configuration.
Quantrova supports two modes in its Agent Handoff tool: -Unified voice mode, where all agents sound the same. -Distinct voice mode, where each agent retains its unique voice for a multi-agent “conference” feel.
None of them own and operate their own infrastructure, they run in the cloud. This means less control over reliability and latency
Traditional platforms often rely on separate tools for voice generation, telephony, orchestration, analytics, and integrations. Quantrova brings these layers together into one voice AI infrastructure platform, helping teams reduce complexity, improve reliability, and launch faster.
Yes! Quantrova supports wideband codecs and 16 kHz+ sampling for crystal-clear HD voice. This helps deliver clearer, more natural conversations for enterprise-grade Voice AI use cases.
