Talking to call

Automate Customer Calls with AI

Most phone answering services stop the moment a call ends. Your AI phone assistant takes instructions, calls people for you and reports back in writing.

Tell Call.io How to Handle Your Calls

Message or call your assistant to set rules, assign tasks, or share new business information. Your updates apply to upcoming calls.

Add a Rule for Specific People

Transfer calls from VIP customers to me today.

Handle all other calls as usual.

Got it. Add the customers you want transferred, and I'll handle everyone else as usual.

Let Call.io Make the Call for You

Confirm appointments, follow up with customers, check on orders, or handle routine calls. Tell Call.io what you need, and it makes the call and reports back with the outcome.

More Than Just Answering Calls

  • A business number of its own

    A dedicated local line for your assistant, or forward the number your customers already dial.

  • Your greeting, your voice

    Write how the assistant opens and closes a call, and choose the voice your customers hear.

  • Call summaries and transcripts

    Who called, what they asked and how it ended. Readable in seconds, searchable later.

  • Spam and robocall screening

    Junk calls are filtered before your phone rings, and screened calls never count towards your usage.

  • AI Receptionist

    Instead of a beep, callers get a conversation. You never miss any of it.

  • Calendar that stays in sync

    Everything booked on a call lands in the calendar your team already uses.

Powerful Features for Every Business

The same voice AI for business, configured differently. What changes is the rules and what it knows, not the product.

Working on your own

You are the business, and every ringing phone interrupts the work people are paying you for.

  • Calls answered while you're on a job
  • Spam handled without your attention
  • Callbacks in a list, not in your head

Call.io is your new team member

More calls arrive than people can pick up, and the missed ones are the expensive ones.

  • Overflow answered instead of ringing out
  • Callers routed to the right person
  • Every conversation on record

Booking by phone

Clinics, salons, studios, restaurants. Most of your calls are somebody trying to get a slot.

  • Appointments taken and confirmed
  • Hours, prices and services answered
  • Reservations called out and chased
