How businesses use AI agents to control Retell AI voice operations, review call outcomes, and manage phone infrastructure without touching a dashboard.
A dental office wants to confirm tomorrow's appointments. An admin asks the AI Agent to call each patient. The agent initiates outbound calls through Retell AI one by one, using the office's provisioned number. Each patient receives a voice call confirming their appointment time. The admin handles the entire batch from a single chat conversation.
After a week of automated sales calls, the team wants results. They ask the AI Agent for a summary. The agent pulls call records from Retell AI filtered by date range and agent ID, returning call durations, statuses, and completion rates. The sales manager reviews performance metrics without exporting spreadsheets from the Retell dashboard.
Your marketing team launches a campaign targeting the 415 area code. They ask the AI Agent to set up a local number. The agent buys a new phone number in that area code through Retell AI and binds it to the appropriate voice agent. The campaign goes live with a local presence, and setup took one conversation instead of a configuration session.

FAQs
The agent calls Retell AI's Create Outbound Phone Call endpoint with a from_number (your Retell-managed number) and a to_number, both in E.164 format. The call starts immediately, and the agent returns the call ID, status, and assigned voice agent details.
Yes. Using the Retrieve Call Details by ID endpoint, the agent fetches the complete call record including type, status, timestamps, agent assignment, and transcript data. This works for both phone calls and web calls processed through Retell AI.
Tars uses a Retell AI API key for authentication. Generate it from your Retell AI account settings and enter it in your Tars dashboard. The key provides access to call management, phone number operations, and voice agent data.
No. Call details, transcripts, and recordings are fetched live from Retell AI during each conversation. Tars does not store, cache, or replicate your voice data. All call records remain under your Retell AI account's control and retention policies.
Yes. The Buy Phone Number endpoint accepts a 3-digit US area code parameter. The agent purchases an available number in that area code and can immediately bind it to inbound and outbound voice agents. Currently, only US area codes are supported.
Retell AI's dashboard is built for detailed voice agent configuration and analytics. Tars adds a conversational layer for operational tasks like triggering calls, checking call history, and managing numbers. Your team performs these actions through natural language instead of navigating platform menus.
Yes. When provisioning or updating phone numbers, the agent can set separate agent IDs for inbound and outbound calls. A number can accept inbound calls with one voice agent while using a different agent for outbound campaigns.
Retell AI currently supports US phone numbers officially. If the agent attempts to call an unsupported number, the API returns an error. The agent relays the error message and suggests verifying the number format or checking regional support availability.
Don't limit your AI Agent to basic conversations. Watch how to configure and add powerful tools making your agent smarter and more functional.
