.// Real-time Actions

Voice agents that do, not just talk.

While on a live call, voice agents can check calendar availability, book appointments, update CRM records, process orders, query databases, and trigger any API — all in real time without leaving the conversation.

.// Built-in Tools

Six essential actions, ready to use.

No configuration needed for common workflows. Check calendars, book appointments, update CRM, query databases, and more — all built in and production-ready.

Check Calendar Slots

Query Cal.com, Google Calendar, Outlook, or custom calendar systems to find available times and present options to the caller on the spot.

Book Appointments

Schedule meetings during the call. Create calendar events, send confirmations, and update your scheduling system without putting the caller on hold.

Transfer Calls

Route the caller to another number, extension, or queue seamlessly while maintaining full call context and conversation history.

Custom API Calls

Hit any REST endpoint to fetch data, trigger workflows, or execute business logic. Define endpoints in seconds via the developer API.

CRM Updates

Create or modify records in Salesforce, HubSpot, Pipedrive during the conversation. Add notes, update fields, and log activities in real time.

Knowledge Base Lookup

Search your documentation, help center, or internal wiki for answers. The agent incorporates findings naturally into the conversation.

.// How It Works

Five steps from conversation to execution.

The entire flow happens in real time. No holds. No delays. The caller hears a seamless conversation while the agent executes behind the scenes.

During conversation

Voice agent is speaking with the caller, gathering information and understanding intent.

LLM decides action is needed

The language model determines that fetching data or executing a task will help resolve the caller’s request more effectively.

Calls external API

Agent hits your endpoint to check inventory, query the database, confirm availability, or trigger a business process.

Receives response

API returns data (calendar slots, order status, product availability, account balance) within 500ms.

Incorporates into conversation naturally

Agent processes the response and speaks the answer directly to the caller without awkward pauses or "let me check that for you."

Real-time action flow: conversation → API call → response → natural incorporation into speech

.// Developer API

Define custom actions in minutes.

Don’t want to wait for pre-built integrations? Define any custom function, endpoint, or workflow. The voice agent can call it during a conversation.

Example: Custom Tool Definition

// Define a custom tool
{
  "name": "check_order_status",
  "description": "Check the status of a customer order by order ID",
  "endpoint": "https://api.yourapp.com/orders/{order_id}",
  "method": "GET",
  "parameters": {
    "order_id": {
      "type": "string",
      "description": "The customer's order number"
    }
  },
  "response_format": {
    "status": "string",
    "tracking_number": "string",
    "estimated_delivery": "date"
  }
}

That’s it. Deploy the tool definition and the voice agent will call your endpoint whenever a caller asks about an order status. The response is parsed and spoken naturally.

.// Real-World Examples

Four scenarios where real-time actions make a difference.

See how voice agents handle complex workflows end-to-end, executing multiple integrations in a single call.

Patient calls clinic

Caller: "I need an appointment next week." Agent checks availability in real time, offers 3 slots, books the appointment, and confirms details — all in one call.

Customer calls about order

Caller: "Where's my order?" Agent queries your order system, retrieves tracking number, provides real-time status, and answers shipping questions without escalation.

Lead calls sales line

Caller: "I'm interested in your product." Agent qualifies the prospect, pulls company information from CRM, scores lead, and creates opportunity — all during the call.

Tenant calls property manager

Caller: "My bathroom faucet is broken." Agent logs maintenance request, checks technician availability, schedules visit, and sends confirmation SMS — completed in 90 seconds.
