AI phone answering for your business

Outsourced Telephone Answering Service

An outsourced telephone answering service is a company or system that answers your business phone calls on your behalf, so you do not have to stop work, hire a front-desk employee, or let calls ring to voicemail. You keep your existing phone number and forward your calls to the service. The service answers using your business information, takes messages, and, depending on the provider, can book appointments or transfer calls to you.

What an outsourced telephone answering service actually does

When you outsource call answering, incoming calls to your business number are redirected to a provider instead of ringing at your desk or cell phone. The provider answers in your business name using details you supply, such as your services, hours, and pricing. Depending on the service, the caller can leave a message, get basic questions answered, book an appointment, or be transferred to you.

Outsourced answering is not the same as hiring a receptionist. An in-house receptionist greets visitors and handles office tasks beyond the phone, so a phone service covers a narrower slice of the job. The trade-off is that you are not paying for a full-time seat, and coverage can extend outside your office hours.

There are two broad styles. Human answering services use trained people to answer calls. Automated services use software, often called an AI receptionist, that answers with a synthesized voice and follows rules you configure. AllDayDesk, the service described on this site, is an automated option: it answers around the clock using your saved business information, and you can hear a personalized sample before you commit.

  • Human services: real people answer, which can help with judgment calls, but plans typically cost more and may have limited hours or per-call fees.
  • Automated services: software answers every call it receives, follows your instructions consistently, and usually costs a flat monthly rate.
  • Both approaches keep your existing phone number; you forward calls rather than change numbers.
  • Both should give you a way to review what happened on each call, such as messages, transcripts, or summaries.

How outsourcing works step by step

The mechanics are simpler than many owners expect. You never give up your phone number, and callers dial the same number they always have. The forwarding step is done with your phone carrier, and the exact method depends on who provides your phone service.

With AllDayDesk, setup starts by choosing your business or entering its website so the system can pull in your details. You check that the information is right, listen to a personalized sample call, and then choose how to connect your phone. The sample is a demonstration only and does not create a real booking. After setup, calls, transcripts, summaries, and any bookings appear in your dashboard so you can see exactly what the service handled.

New appointments go on the built-in AllDayDesk dashboard calendar by default, once you have configured your services and availability. If you prefer, you can optionally connect Google Calendar in Settings after authorizing your Google account. Other calendar or scheduling software connections are not part of the product.

  • Step 1: Pick a provider and share your business details, services, and hours.
  • Step 2: Review and approve how your calls will be answered; hear a sample first.
  • Step 3: Forward your number to the service using your carrier's instructions.
  • Step 4: Check the dashboard regularly to review messages, transcripts, and bookings.

Forwarding your number: what your carrier controls

Forwarding instructions are set by your phone carrier, not by the answering service, and they differ by product. As examples from published carrier guides: Verizon mobile uses *72 plus the destination to forward all calls and *73 to turn it off, while T-Mobile uses **21*1 followed by the number and # for unconditional forwarding. AT&T Phone for Business uses *72, the destination, then #, and Spectrum Business Voice manages forwarding through its online portal instead of star codes.

Two cautions matter. First, identify your exact product before using any code, because the same carrier often has different instructions for wireless, landline, and hosted business products. Second, Google Voice does not support forwarding calls from a Google Voice number to an automated system, so that setup path is not available.

If your carrier's guide does not list a code for your situation, call their support line and ask for call forwarding on your specific plan. Conditional forwarding, which only sends calls when you are busy or do not answer, is a separate feature from all-call forwarding and is not supported on every plan.

  • All-call forwarding sends every incoming call to the service immediately.
  • Conditional forwarding sends calls only when you are busy, do not answer, or are unreachable, depending on what your plan supports.
  • Always test forwarding with a real call from another phone after activating it.
  • Charges may apply depending on your plan; check with your carrier.

What outsourced answering costs

Pricing falls into a few patterns. Human virtual receptionist services commonly charge monthly plans or per-call rates; for example, Ruby advertises plans starting at $245 per month as of October 2026, and Smith.ai uses per-call pricing for its human receptionist service. Starting prices are not the whole picture, since included minutes, overage rates, hours, and contract terms all change the real cost.

Automated services are usually priced by monthly plan with an included minute allowance. AllDayDesk plans include a set number of minutes each month with a per-minute rate for overage, and current pricing is shown on the plans section of this site rather than in this article.

To compare quotes fairly, ask each provider the same questions: what is included, what happens when you exceed the allowance, what hours are covered, whether transfers and booking are included, and whether there is a contract or cancellation fee.

  • Human services: often per-call or higher monthly minimums; verify hours and overage terms on a current quote.
  • Automated services: flat monthly plans with included minutes; overage is charged per minute.
  • Hidden costs to check: setup fees, per-transfer charges, holiday rates, and contract length.
  • Compare against the cost of your own time or a part-time hire, not just against zero.

How to decide if outsourcing fits your business

Outsourced answering makes the most sense when calls interrupt work you cannot pause, when you miss calls while on a job, or when you want coverage outside office hours without hiring. If most of your calls are scheduled or routine, an automated service handles them well. If callers frequently need complex judgment, a human service may fit better.

Before signing up, be clear about what the service will and will not do. A good provider answers with your business information, takes complete messages, and books appointments only against availability you have configured. When the answer, price, or appointment time is unknown, the right behavior is to take a message for you rather than guess. Changes to existing appointments should come to you as requests, not silent confirmations.

Also understand the limits. Transfers to you require you to configure a destination and rules, and no service can guarantee a caller reaches you on a given call. Around-the-clock availability describes when the service can answer, not a promise that every call connects. Ask each provider directly how they handle a transfer that goes unanswered before you rely on transfers.

  • Choose automated if your calls are mostly routine: hours, pricing, directions, and new bookings.
  • Choose human if callers often need nuanced handling or you want a person's voice.
  • Confirm how messages, transcripts, and bookings reach you, and how quickly you can review them.
  • Ask what happens when the service does not know an answer; the correct answer is that a message is taken.
  • Make sure appointment booking uses a calendar you control, with availability you set.

More questions, answered

Do I have to change my business phone number?

No. You keep your existing number and forward calls to the service. Callers dial the same number they always have.

Can the service book appointments on my calendar?

AllDayDesk books new appointments on its built-in dashboard calendar once you have set up your services and availability. You can optionally connect Google Calendar in Settings after authorizing your Google account. Other calendar software is not supported.

What happens when the service cannot answer a caller's question?

When an answer, price, or appointment time is unknown, the service takes a message so you can follow up. It does not guess.

Can callers be transferred to me?

Yes, if you configure a transfer destination and rules. Transfers are not guaranteed to reach you, so ask any provider how unanswered transfers are handled before relying on them.

Can I use Google Voice with an answering service?

Google states that forwarding calls from a Google Voice number to an automated system is unsupported, so that path is not available. A traditional carrier line with forwarding is the usual route.

How do I know what the service said to my callers?

With AllDayDesk, calls, transcripts, summaries, and bookings appear in your dashboard, so you can review what the service handled.
