Never lose a missed call again: turn Onoff Business calls into leads

When you can't pick up, the customer often calls someone else. Connect your Onoff Business line to VeyCall and every missed call and voicemail becomes a lead you can call back in one tap.


You're with a customer, on a ladder, or driving between jobs. The phone rings and you can't answer. By the time you look at it, you have a number, maybe a voicemail, and no idea whether it was a quick question or an emergency. Some of those callers won't wait: they call the next business on their list.

If your business uses an Onoff Business line, VeyCall now catches those calls for you. Every missed call and every voicemail becomes a lead in your dashboard, with the message already written out and urgent requests flagged.

What happens when you miss a call

  1. A lead appears in VeyCall with the caller's number, the Onoff line they called and the time. If they try again the same day, the same lead shows "2 calls" instead of a duplicate.
  2. The voicemail is transcribed. No need to listen to it in a hurry: you read it in a few seconds, and the recording is there if you want to hear it.
  3. The AI reads the message for you. It picks out the caller's name, what they want, whether it's urgent (a leak, pain, a same-day need) and any appointment they asked for.
  4. You get an email alert, marked urgent when it is. From the lead, you call back or send a WhatsApp message in one tap.

Calls you answered, outgoing calls and hidden numbers with no message are left out, so your leads list stays about the people you still need to call back.

Set it up in two minutes

  1. In VeyCall, open Integrations and click Connect Onoff. Copy the webhook address and the key.
  2. In the Onoff Business admin interface, open the call webhook settings. Paste the address, paste the key in the "API Key" field, and save.

That's it. Your next missed call shows up in Leads. The full steps are in the documentation. The call webhook is an Onoff Business feature: check with Onoff that it's included in your Onoff plan.

Your website and your phone, in one place

On your website, your VeyCall agent already answers visitors out loud, day and night, and takes their details. With Onoff connected, the calls you couldn't take land in the same list. One place to see who's waiting for you, whether they came through your site or your phone.

Which plan do I need?

The Onoff connection is included from the Business plan ($49 a month), along with 5 AI agents and 5,000 voice minutes. Using another phone system? Tell us which one: the integrations we build next are the ones customers ask for.
