AI voice agent for call overflow: nobody waits on hold when your line is busy

InfiVoice ยท 2026-11-14

An AI voice agent takes the calls your team can't pick up at that moment, answers questions from your own information, books an appointment or passes the call to a person. InfiVoice does it with a visual flow builder, in more than 30 languages and with a free plan of 100 credits.

Why calls get lost at peak times

A technician on a job, a receptionist at the front desk or a sales rep on another call can't answer everything that comes in. A caller who hears no answer within seconds often hangs up and tries the next provider. The problem isn't lack of interest. The line is busy at the exact moment the customer needs you.

How overflow works

You set your number so that calls nobody picks up go to the voice agent. The agent greets the caller, finds out why they are calling and answers frequent questions using your knowledge base (RAG). If the caller wants an appointment, it books it on your Google Calendar. If they need a person, it transfers the call.

What your team sees afterwards

When they are free again, they receive the details of each handled call through a webhook or in a Google Sheets spreadsheet. The reason for the call and the caller's name are kept, and your team can call back or review the booked appointment.

Overflow and handoff to a person

The agent doesn't have to replace your team for everything. You decide which calls it handles and which go straight to a person, such as an emergency or a complaint. If you want to see how the handoff works, read how to hand off AI voice agent calls to a human.

How much it costs

InfiVoice has a Free plan with 100 credits and a Pro plan at $79 per month with 250 credits. One credit equals 60 seconds of call time, so you can test overflow with real calls before you pay. Check the details on the pricing page.

Getting started

Define which calls the agent takes, load your services and hours into the knowledge base, connect your calendar and assign the number. Simulate a busy hour with test calls and adjust the flow before going live.

Frequently asked questions

Can the agent take calls when my team is busy?

Yes. Calls that aren't answered move to the voice agent, which picks up, answers questions and books or transfers based on your setup.

Can I decide which calls go to a person?

Yes. You set the rules in the flow, for example emergencies or complaints, and the agent transfers them without trying to resolve them.

Which tools does it connect to?

InfiVoice connects today with Google Calendar, Google Sheets and webhooks. See the integrations page for the current options.
