The AI voice agent that answers your calls
Allo's AI voice agent picks up in two rings, day or night. It talks with your callers in a natural voice, answers from what you taught it, books them on your real calendar and hands the ones that need a person to your team.
What is an AI voice agent?
Software that talks back
An AI voice agent is software that answers a phone call and talks with the caller in natural speech. Unlike a voicemail or a phone menu, it understands what the caller asks, answers it, and takes an action: a booking, a transfer, a message. On Allo, the voice agent works on your business number and every call it takes lands in your inbox and your CRM.
One agent on your line, trained on your business.
It listens and understands
Callers speak normally, no keypad and no script. The agent follows the conversation, including your own product names and jargon.
It answers and acts
It answers from your website and documents, books a slot that is really free, or transfers the call to the right teammate with the context.
It writes the call up
Every call is recorded, transcribed and summarised, then synced to your CRM. Nobody types a note.
One call, step by step
From hello to CRM
Open each step to see the agent at work, on the kind of desk it answers for.
It greets the caller, understands what they need and answers from your website and documents.
It reads your calendar and books a time that is really free before the caller hangs up.
A hot lead or a specific request goes to the right teammate, with the caller's details already open.
Recording, transcript and summary land in your CRM, so nobody types a note.
What it handles today

AI voice agent vs. the other ways to answer
Voicemail, a phone menu or a human answering service all pick up. Only one of them can hold the conversation, act on it and write it up.

AI voice agent
questions, answered
An Allo agent picks up and puts you through to sales or support. It is the fastest demo on this page.
888-298-ALLOAnything else? Our team picks up, and so does the agent.
An AI voice agent is software that answers phone calls and talks with callers in natural speech. It understands the request, answers questions from what your business taught it, and takes actions like booking an appointment or transferring the call. Allo's voice agent runs on your business number and logs every call it takes in your CRM.
An AI receptionist is an AI voice agent whose job is answering a business's incoming calls. On Allo they are the same agent: the AI receptionist is Allo's voice agent for inbound calls.
A phone menu makes callers press keys and only routes them. An AI voice agent lets them say what they need, answers the question itself, and only transfers when a person is really needed. Allo also offers an AI IVR for teams that want spoken routing in front of their lines.
Not today. Allo's voice agent answers inbound calls; it does not place them, so it is not a cold-calling agent. For collections, see how the agent and your team split the work on the AI collections agent page. For outbound, your team calls with Allo's power dialer or parallel dialer, and the AI writes up every call. More agents are on the roadmap for the Ultra plan.
It speaks with natural, lifelike voices through Allo's partnership with ElevenLabs. You pick the voice and the greeting, and preview the conversation before it goes live.
It talks with callers in several languages, including English, French and Spanish, and transcribes and summarises each call in the caller's language.
On Allo the agent takes one Business seat: $32 a month billed yearly in the US, 35 € in Europe. Transcripts, summaries and CRM sync are included, and there is a 7-day free trial.
Yes. It connects to Google Calendar, Outlook, Calendly or Cal.com, offers only the slots that are really free, and books the caller while they are on the line. See AI appointment booking.
Yes. You set the rules: it can hand a hot lead or a specific request to the right teammate, with the caller's details already open, and take a detailed message for everything else.
