    Availability gets checked, the appointment rescheduled, and the new slot confirmed on the call.

  • Troubleshooting

    Customers get walked through the fix, or handed off the moment a person is needed.

Capabilities

Everything a voice agent needs to hold a real conversation.

Ultra-low latency

Latency stays consistently low, so the agent never leaves a customer sitting on dead air.

<20ms

one-way streaming latency

300–500ms

end-to-end latency

Voice intelligence

The agent detects speech, filters background noise, and tells a real interruption from silence.

  • Voice activity detection
  • Interruption strategy
  • Noise suppression

Agentic reasoning

The agent decides what happens next. It reads intent, pulls context, calls tools, and adapts when the customer goes off script.

  1. Fetch customer information
  2. Check availability and look up orders
  3. Update CRM and trigger API
  4. Escalate to a human

Multilingual, 30+ languages

Native support across 30+ languages, not one voice translated 30 ways, even when a customer switches language mid-sentence.

  1. Create the bot

    Define the prompt, tools and knowledge sources. No orchestration logic to write.

  2. Attach a number

    Provision Exotel's virtual number, or point your own SIP trunk at us. No infrastructure to stand up.

  3. Go live

    One click turns the bot into a live call flow, with a ready endpoint.

Every regulated call is a compliance risk waiting to happen.

FAQs

The things buyers ask first.

What can Exotel Voice AI agents handle?

Customer support, sales, collections, operations and marketing workflows, including information retrieval, qualification, verification, scheduling, payment conversations, outbound calling, backend actions and human handoff.

How many languages do you support?

30 languages across Indian and international markets.

Can we use our own AI models?

Yes. You can bring your own model, endpoint or key.

Can the agent access our backend systems?

Yes. Agents can connect to CRMs, APIs, databases, dialers and other business systems.

Can we combine AI with deterministic workflows?

Yes. Decision-tree flows can run alongside AI-driven reasoning, so you can use rules where precision matters and the model everywhere else.

Can the agent hand over to a human?

Yes. Calls transfer with context, and a supervisor can intervene mid-call.

Can it work with an existing legacy contact centre setup?

Yes. StreamKit Cloud connects existing contact-centre infrastructure to Voice AI through managed SIP-to-WebSocket connectivity.

Can we enforce steps that must happen before a call ends?

Yes. Required actions make sure critical workflow steps happen before the conversation is allowed to end.

How do we test the agent?

Synthetic calls and defined test scenarios, before the agent goes anywhere near production.

How do we measure performance?

Containment, CSAT, conversion, latency and conversation quality, scored on every call rather than a sample.

Where can we deploy it?

Public cloud, private cloud, on-premise, or split across providers depending on your architecture.

How quickly can we go live?

Standard workflows typically go live in one to two weeks. Regulated deployments take four to six weeks or longer, depending on integrations, security assessment, data residency and UAT.
