Online Telephone Answering Service: How It Works and How to Set One Up

An online telephone answering service is a service that answers calls to your business number without you having to pick up. The word online means the service is delivered over the internet: you manage it through a web dashboard, and the service uses your saved business details — services offered, hours, pricing you choose to share — to handle each conversation.

This is different from a voicemail box. A voicemail records a message and waits. An answering service talks with the caller, tries to answer questions from your saved information, and takes a message when it does not know an answer, a price, or an available appointment. It can also book new appointments once you have set up your services and availability.

AllDayDesk is one example of this kind of service. It answers calls around the clock using your business information, and you can hear a personalized sample of how it would sound for your business before turning anything on.

• You keep your public phone number; calls are forwarded, not moved.
• The service answers using business details you save and review.
• Messages, transcripts, summaries, and bookings appear in an online dashboard.
• A sample greeting creates no real booking — it is just a preview.

When someone calls your business number, your phone service forwards the call to the answering service. The service greets the caller, uses your saved business information to answer questions, and records what was said.

If the caller wants an appointment, the service can book one using the built-in AllDayDesk dashboard calendar, as long as you have configured your services and availability first. If you have connected Google Calendar in Settings and authorized your account, that optional connection can be used instead. New bookings are confirmed; changes to existing appointments are passed to you as requests, since the service does not rewrite appointments you already made.

If the service does not know an answer, a price, or an opening, it takes a message instead of guessing. You see the message, the transcript, and a summary in your dashboard. If you have configured a transfer destination and rules, the service can also transfer calls to you — though pickup and immediate response are not guaranteed, since that depends on whether you answer.

• Caller dials your normal business number.
• Your phone provider forwards the call to the service.
• The service answers using your saved business details.
• Unknown answers, prices, or openings become messages, not guesses.
• New appointments go to the dashboard calendar by default, or Google Calendar if you connect it.

You do not need a new phone number. You keep your public number and forward calls to the service. The exact steps depend on your phone provider, because each one uses its own codes or portal settings. Check which product you actually have before following any instructions, since the same carrier often has different steps for wireless, landline, and hosted business services.

Some verified examples: Verizon mobile uses *72 plus the destination for all calls, *71 for unanswered calls, and *73 to turn forwarding off. T-Mobile uses **21*1 followed by the destination and # for unconditional forwarding, with ##21# to disable. Spectrum Business Voice manages forwarding through the SpectrumBusiness.net portal under Voice Settings or Forwarding Manager, where you choose all calls or busy/no-answer. Optimum Business Phone uses *72, then the destination, with *73 to disable. These are examples only — always confirm the steps for your exact service.

Google Voice is a special case: Google states that forwarding calls from a Google Voice number to an automated system is unsupported, so a Google Voice number cannot be forwarded to this kind of service.

• Identify your exact product (wireless, landline, or hosted voice) before using any code.
• Most providers use *72/*73 style codes or a web portal setting.
• Conditional forwarding (busy or no-answer only) is a separate feature and is not supported everywhere.
• Verify forwarding worked by placing a test call from another phone.

Not all online answering services work the same way, so it helps to compare a few things directly. Some use people to answer calls; others use software; some, like Smith.ai, offer both a human receptionist service and a separate AI receptionist product. Human services such as Ruby and AnswerConnect advertise around-the-clock people, and their pricing and coverage vary by plan, so check current quotes rather than assuming one model is always cheaper.

When comparing, look at how the service learns your business details, whether you can hear a sample before committing, where booked appointments land, and how you review messages and transcripts. Also check what happens when the service cannot answer something — a good service takes a message rather than guessing.

Cost structure matters too. Some services charge per call, some per minute, and some include a monthly allowance of minutes with overage rates. Compare the included allowance against your actual call volume, not just the base price.

• Human answering, software answering, or a mix — check which you are buying.
• How the service learns your business: website entry, saved details, or agent training.
• Where appointments are booked and whether changes to existing ones reach you.
• Pricing model: per call, per minute, or monthly allowance with overages.
• Whether you can preview the service before turning on forwarding.

Setting up AllDayDesk starts with choosing your business or entering its website, so the service can pull in your details. You then check those details, hear a personalized sample of how your calls would be answered, and choose your phone setup. The sample creates no real booking — it is only a preview.

After that, you turn on forwarding with your phone provider using the steps for your specific service. Once calls flow in, you configure your services and availability so new appointments can be booked into the dashboard calendar, and optionally connect Google Calendar in Settings if you prefer. From then on, calls, transcripts, summaries, and bookings are all visible in your dashboard.

• Enter your business or website, then review the details it finds.
• Listen to the personalized sample before going live.
• Choose phone setup and enable forwarding with your provider.
• Configure services and availability to enable appointment booking.
