The problem
Where phone calls still fall through the cracks
Phones are still where high-intent customers go first, and most businesses are not set up to answer them all.
- Calls arrive faster than a team can answer them, and the overflow goes to voicemail
- Phone menus make callers work to reach the thing they called about
- Follow-up calls, reminders and screening happen late or not at all
- What was said on a call rarely reaches the CRM in full
- Cover for nights, weekends and peaks means paying for hours nobody calls
The basics
What is an AI voice agent?
An AI voice agent is software that holds a spoken phone conversation, understands what the caller needs and completes the task on the call. Speech recognition turns the caller’s words into text, a language model decides what to do, and a natural voice replies, usually in under a second. The agent answers from your knowledge base, books into your calendar, qualifies the caller against your rules, and writes the result to your CRM. Unlike an IVR it needs no menu, and unlike a chatbot it works on the phone, where the customer already is.
In short
- Talks in natural speech, not a keypad menu
- Answers inbound and places outbound calls
- Books, qualifies and screens on the call
- Writes every outcome to your CRM
Where it fits
AI voice agents, by use case
“AI voice agents” covers a few different setups, depending on whether the job is answering calls, making them, or doing either for one specific industry.
Outbound AI voice agent
Places the calls your team never gets to: appointment reminders, lead follow-up, application screening and payment nudges, with retries and voicemail rules built in.
AI receptionist and answering service
The front-desk role, covered around the clock: greeting, FAQs, booking, message-taking and routing to the right person.
Industry voice agents
The same engine configured for the calls a sector actually gets, from patient intake and vet triage to candidate screening and dealership service bookings.
Key capabilities
What an AI voice agent handles
Natural Conversation
Understands free speech, handles interruptions and replies in well under a second, with no "press 1" menu.
Appointment Booking
Checks live availability and books, moves or cancels in your calendar during the call.
Lead Qualification
Asks your qualifying questions, scores the answer and passes only the callers worth your time.
Outbound Campaigns
Reminder, follow-up and screening calls at volume, with retry timing and voicemail handling.

Multilingual Support

How it works

1
A call starts
The caller rings in, or the agent places the call from your list or CRM trigger.
2
Speech is understood
Speech recognition and a language model work out intent from natural talk, not a menu.
3
The agent acts
It answers from your knowledge base, books, qualifies or transfers, following the rules you set.
4
The record is written
Summary, transcript and outcome land in your CRM, with urgent items flagged to your team.

How it compares
AI voice agent vs a phone menu (IVR)
| Capability | Centricall | Keypad IVR menu | What it means for you |
|---|---|---|---|
| Understands free speech | Yes, no menu | Keypad options only | Callers say what they need instead of navigating for it. |
| Completes the task | Books, qualifies, answers | Routes to a queue | The caller leaves with an outcome, not a transfer. |
| Simultaneous calls | Unlimited | Limited by lines or staff | A rush is answered together, not one caller at a time. |
| Outbound calling | Built in | Not supported | Reminders and follow-up run without a dialling team. |
| Hours covered | 24/7, same quality | Menu only after hours | Out-of-hours callers get a conversation, not a recording. |
| CRM logging | Automatic | Manual or none | Every call is on record without anyone typing it in. |

FAQ
AI voice agent FAQs
Everything you need to know before you switch.
An AI voice agent is software that holds a spoken phone conversation. It understands what a caller says, replies in a natural voice, and completes the task on the call: answering a question, booking an appointment, qualifying a lead or screening a candidate. It then writes the outcome to your CRM.
An IVR plays a menu and routes on keypad presses. An AI voice agent listens to free speech, works out intent and does the work itself, so the caller is not routed through a tree to reach someone who can help.
Yes. The same agent places reminder, follow-up and screening calls, with retry timing and voicemail rules you set. Outbound campaigns must respect consent and calling-hour rules for the region you call.
Centricall publishes three plans: Starter at $49 a month with 50 included minutes, Growth at $149 with 120, and Professional at $299 with 300, with per-minute overage between $0.15 and $0.20. Larger deployments are quoted against peak concurrency and integrations.
Anywhere the phone decides the outcome: healthcare practices, recruiters, law firms, car dealerships, home services, real estate, restaurants and veterinary clinics all run agents for booking, intake, screening and after-hours cover.
Modern voices pass a first listen, and the agent handles interruptions naturally. We recommend disclosing that the caller is speaking with an AI, and some jurisdictions require it; the greeting is yours to write.
Yes. Your current number is routed to the agent, and call outcomes are written to HubSpot, Salesforce, Zoho and other CRMs through native or API integrations.
Yes. Agencies and resellers can license the platform under their own brand, and enterprises can run it on their own infrastructure under an on-premise license.
