SHEET 02Built-in ToolsTOOL-01..06

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.

TOOL-01Ready

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.

TOOL-02Ready

Book Appointments

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

TOOL-03Ready

Transfer Calls

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

TOOL-04Ready

Custom API Calls

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

TOOL-05Ready

CRM Updates

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

TOOL-06Ready

Knowledge Base Lookup

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

SHEET 03How It WorksFLOW

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.

Conversation to execution pipelineLive
01During conversation

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

02LLM decides action is needed

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

03Calls external API

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

04Receives response

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

05Incorporates 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."

SHEET 05Real-World ExamplesUC-01..04

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.

UC-01Voice

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.

UC-02Voice

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.

UC-03Voice

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.

UC-04Voice

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.
