  1. Number. Search, buy and configure numbers with KYC done online.
  2. Connect. Bind the number to your Vapi, Retell, LiveKit or Bolna agent in the dashboard.
  3. Stream. Live audio flows both ways while your agent talks.
  4. Observe. Webhooks, recordings and call records for every call.

Infrastructure only

We don’t build agents. We connect them.

Some telephony providers now sell their own AI agents. TryVox is only the phone layer, so agent platforms and builders can run on us without feeding a competitor. Keep the voice stack you already trust, with no lock-in.

FAQ

Questions teams ask first.

What is TryVox?

TryVox is telephony infrastructure for voice AI. We provide phone numbers, SIP trunking, programmable voice APIs, call routing and real-time call events that connect any AI voice agent to the phone network.

Do you provide an AI voice agent?

No. You bring your own agent, built on Vapi, Retell, ElevenLabs, LiveKit, Bolna or your own code, and we connect it to real phone calls.

Can I get Indian phone numbers for my AI agent?

Yes. Local, national and toll-free numbers, with business KYC and India's telecom requirements handled during setup.

How do I connect TryVox to Vapi or Retell?

Open AI Agents in the dashboard, pick your provider and click Connect number. Choose a TryVox number and an agent, confirm, and the agent answers calls on that number straight away. No SIP setup needed.

Is TryVox only for voice AI?

No. The same account covers SIP, programmable voice, WhatsApp, SMS and alerts.

How is TryVox priced?

Pay as you go, billed per minute, with a ₹100 setup fee, ₹399 monthly rent and no lock-in. Use the estimator above and ask for a rate card for your volume.

Is TryVox an alternative to Exotel, Plivo or Twilio for voice AI?

Yes, for teams running AI voice agents in India. TryVox puts Indian numbers, SIP trunking, a Voice API, agent bindings and DLT-ready messaging on one account, and never sells its own agents.
