An AI voice agent is an AI agent that holds phone conversations: it understands the caller, decides what to do and answers out loud in real time. Rexenda's voice agent answers and makes phone and WhatsApp calls, books appointments and updates your CRM during the call, then leaves the transcript and a summary in your inbox.
When nobody picks up, the customer calls someone else
Your front desk is busy, you're closed or the line is taken, and the call goes to voicemail. The caller hangs up and tries the next business.
Hiring and training receptionists to cover evenings, weekends and peak hours is expensive and hard to sustain.
Calling leads back, confirming appointments and following up take hours of manual dialing, and the notes rarely make it into the CRM.
A receptionist that talks, listens and gets things done
The voice agent uses the same setup, knowledge and actions as your Rexenda AI agents, now over the phone.
Natural conversation, interruptions included
It speaks natural Spanish by default and detects other languages, such as English. Callers can interrupt at any moment, and the agent listens and adjusts the way a person would.
Books and updates during the call
While talking, the agent checks availability, books or moves meetings, saves the caller's details and updates the pipeline. No notes to type up afterwards.
Transcript and summary in your inbox
Every call lands in the inbox and CRM with its full transcript and a summary, right next to the customer's chats and emails.
Outbound calling campaigns
Run an auto-dialer with calling windows, retries, cooldowns, a do-not-call list, quiet hours and daily caps per contact, so outreach stays respectful.
A person when it matters
When a caller needs someone from your team, the agent rings a colleague, who can answer from the browser softphone and take over the call.

Get a phone number
Buy a number inside the app, and Rexenda guides you through each country's regulatory paperwork. You can also connect WhatsApp calling.
-
Set up the agent
Start from a template or describe the job: greeting, questions to ask, tone and when to pass the call to a person.
-
Make a test call
Call the agent yourself and hear how it handles the conversation. An agent can only be activated after a successful test call.
-
Turn on inbound or outbound
Switch it on to answer incoming calls, launch an outbound calling campaign, or both.
Good to know
- Voice minutes are paid from the same AI credits as the rest of your AI usage. Each plan includes monthly credits, and you can buy extra packs.
- Phone numbers are a separate monthly charge. Some countries require identity or address documents before a number is assigned.
- The agent never hangs up on a person mid-conversation. It only ends a call after a long silence or if your workspace runs out of credit.
Questions about the AI voice agent
What is an AI voice agent?
An AI voice agent is an AI that holds phone conversations for your business. Rexenda's voice agent answers and places phone and WhatsApp calls, understands what the caller needs, books meetings, updates your CRM during the call and leaves a transcript and summary in your inbox. You define its tone, questions, rules and when to bring in a person.
Can AI answer my business phone calls?
Yes. Get a phone number in Rexenda or connect WhatsApp calling, and the voice agent answers on the schedule you choose, including nights and weekends. It greets callers, answers questions from your knowledge base, takes their details and books appointments. If a caller asks for a person, it rings someone on your team.
Does the AI voice agent speak Spanish?
Yes. It speaks natural Spanish by default, which suits businesses serving Mexico and Latin America, and it detects and answers in other languages, such as English, when the caller uses them. Callers can interrupt while it speaks, and it responds to what they just said, so the conversation sounds natural rather than scripted.
How much does an AI receptionist cost?
You can start on the free plan, with no time limit and no credit card. Voice minutes are paid from your AI credits: each plan includes a monthly allowance, and you can buy extra packs. Phone numbers are a separate monthly charge. Current prices for plans and credits are on the pricing page.
Can AI make outbound calls to my leads?
Yes. The voice agent can call customers back and run outbound calling campaigns. You set calling windows, retries and cooldowns, and it respects your do-not-call list, quiet hours and daily caps per contact. Every call is transcribed and summarized in the inbox, and the outcome updates the lead in your CRM.
