Why add OneCalling to your campaigns

  • The channel everyone answers

    Reach by phone the people who don’t read email or messages, with a clear, direct notice.

  • AI conversations

    A voicebot understands what the person says, replies on the spot and hands off to an agent when needed.

  • Calls at the right time

    Every campaign respects the time window you set, in the recipient’s time zone.

  • Results for every call

    Answered, voicemail, busy or no answer, live and per campaign.

How it works

  1. 1

    Create the message

    Upload a recording, write text with variables for text-to-speech, or combine both.

  2. 2

    Set up the campaign

    Choose the audience, calls per minute, time window and retries.

  3. 3

    Test before launch

    Get a test call on your own phone and adjust whatever you need.

  4. 4

    Launch and measure

    Follow every result live and pause, resume or cancel at any time.

Features

  • Recorded audio

    Use your own MP3 or WAV recordings for a natural-sounding message.

  • Personalized text-to-speech

    Text with per-recipient variables such as name, amount or due date.

  • Mixed blocks

    Combine a recorded intro, a personalized detail and a recorded closing.

  • AI voicebot

    Confirms appointments, reschedules, records promises to pay or runs surveys by talking.

  • Time window and retries

    Call only within allowed hours and retry unanswered calls with a wait between attempts.

  • Do Not Call list

    Exclude numbers manually or by CSV; anyone who asks not to be called is left out.

  • Controlled pace

    Set how many calls per minute go out so you don’t overload your team or capacity.

  • Campaign reports

    The outcome of every call and per-recipient detail to support decisions.

    Due-date reminders and collection notices that record promises to pay.

  • Healthcare

    Appointment confirmation with the option to reschedule on the same call.

  • Retail and services

    Satisfaction surveys and promotional notices to the whole base.

  • Utilities and telco

    Notices of scheduled outages, technician visits and due dates.

Frequently asked questions

Can I personalize what each person hears?

Yes. With text-to-speech, your list’s variables are read on every call: name, amount, date or any field.

What if they don’t answer?

The campaign retries as many times as you set, with a wait between attempts and always within allowed hours.

How do I handle people who don’t want calls?

With the Do Not Call list. If you use a voicebot, anyone who asks not to be called is added automatically.

Does it connect with my bots and agents?

Yes. The call can go to an AI voicebot and, from there, to a human agent when the case requires it.
