How does an answering service work?

Forwarding is the part most people haven't seen before. Your phone company sends calls to the service's number in one of four modes. It can forward every call, calls when you're busy, calls you don't pick up, or calls when your phone is off.

You pick the mode and the ring delay at your carrier, not at the service. Verizon uses a fixed delay of about 30 seconds on no-answer forwarding. AT&T and T-Mobile let you pick between 5 and 30 seconds. A VoIP system sets it in its own dashboard.

Once a call arrives, someone has to know your business. A human service briefs its receptionists with a script. An AI service works from the hours, services and FAQs you give it.

Billing follows who answers. Human services mostly charge by the minute, like Ruby at $250 for 50 minutes or PATLive at $99 for 50 minutes, as of September 2026. AI services tend to charge by the call or by the month.

Your phone rings and the call forwards. On no-answer forwarding, you still get the first rings to pick it up yourself.

The service greets the caller in your business name and asks what they need. Good services put any recording or AI disclosure in that first line.

Next comes the job itself. A message means the caller's name, number and reason. A transfer means ringing your team. A booking means writing the appointment into your calendar.

Finally, the result reaches you. Older services email or text a message slip. Newer ones send a transcript, a summary and a webhook your other tools can pick up.

GreetKeeper gives you a dedicated local number, with the area code you choose at signup. It answers calls forwarded in any of the four modes. The ring count is set where the forwarding is set, and GreetKeeper answers the moment the call arrives.

It reads the caller's details back before it books into Google Calendar or Microsoft Outlook. When a caller asks for a person, it transfers to your team and tries a second number you nominate if the first isn't picked up.

After each call you get a transcript and a short summary, and the on-call person gets a text. The caller gets one text with the booking link or the confirmation. Plans are $49, $149 and $349 a month, with a 14-day free trial and no card.
