AI voice & IVR agents that pick up.
Configure an agent for inbound calls, outbound conversations and browser voice. It speaks the caller’s language, lets them interrupt, looks things up mid-call and hands over to a person when it should.

The call finds its way.
Build the path a call takes from real parts: a greeting, a business-hours check, a keypad menu, a route, voicemail, a webhook. Any branch can end at an AI agent, a queue, a phone number or another menu, so the agent and the keypad work together.
Numbers, menus, queues and supervision live in Call operations. Moving off a keypad-only system? IVR replacement.

It answers in the caller’s language.

- Speech to speech
- One model listens, reasons and speaks, for the most natural turn-taking.
- Cascaded pipeline
- Speech-to-text, a language model and text-to-speech as streaming layers. Pair any text model with a specific voice.
- Fallback tiers
- Set a primary model and fallbacks. If one is unavailable, the call rolls over to the next.

It listens while it talks.
When the caller cuts in, the agent stops and listens. When it needs a fact, it uses a tool during the call: your knowledge, a connected store, your own API.
The agent itself is built once in the AI agent builder and can answer WhatsApp calls too.

Voice agent questions
What is an AI voice agent?
An AI voice agent is software that answers or places phone calls, understands what the caller says in natural language, and replies in a natural-sounding voice in real time. Unlike a keypad-only IVR, the caller can simply say what they need.
Can it replace my existing IVR?
It can sit in front of, beside or in place of a keypad menu. Call flows combine a greeting, a keypad menu, business hours, routing, voicemail and webhooks, and any branch can route to an AI agent, a queue, a phone number or another menu.
How does the voice agent work?
Two ways, chosen per agent. A speech-to-speech model listens, reasons and speaks in one model for the most natural turn-taking. Or a cascaded pipeline runs speech-to-text, a language model and text-to-speech as streaming layers, so you can pair any text model with a specific voice. You can set fallback tiers so a call rolls over to the next model when one is unavailable.
Can callers interrupt the agent?
Yes. When the caller starts speaking, the agent stops talking and listens, then answers the new request.
Can the same agent answer WhatsApp calls?
Yes. The same voice agent can answer and place calls over WhatsApp Business Calling, sharing its knowledge, tools and escalation rules with your phone calls.
What does a voice agent cost?
Speech-to-speech voice models are billed from $0.05208 (₹5) per minute from your credits, with no separate orchestration fee. Cascaded stacks can cost less, premium realtime models cost more, and telephony is a separate line. Every account starts with 1,000 free API credits.
Calling requires enabled telephony, eligible numbers, credits and applicable consent. Concurrency and availability depend on your account and carrier configuration. Respect local calling and outreach rules.
