Answering Service Companies: How They Work and How to Choose One

Answering service companies take your business calls when you can't pick up. Some use trained people to answer, some use automated voice systems, and some mix both. You keep your existing phone number and forward calls to the service, so callers dial the same number they always have. This guide explains the main types of answering service companies, what they usually cost, what to check before signing up, and how to set one up. It also covers where AllDayDesk, an AI receptionist service, fits in the category.

What Answering Service Companies Do

An answering service company answers calls on behalf of your business. Instead of a call going to your voicemail when you're on a ladder, with a customer, or after hours, it goes to the service. The service answers in your business name, takes a message, and passes the details to you.

Most services work through call forwarding. You dial a short code or use your phone provider's settings to send calls to the service's number. Callers still see and dial your regular business number, so nothing changes on their end. Setup instructions depend on your phone carrier, so it helps to know exactly which service and plan you have before you start.

Calls are answered in your business name using information you provide
You keep your existing phone number and forward calls to the service
Messages, call details, and sometimes bookings are delivered to you through a dashboard or app
Coverage can be during business hours, after hours, or around the clock depending on the plan

The Main Types of Answering Service Companies

Not all answering service companies work the same way. Knowing the main types makes it easier to compare quotes and pick the right fit.

Human answering services: trained agents answer your calls, follow a script you approve, and take messages. Companies like AnswerConnect offer 24/7 live answering by people, and Ruby offers human virtual receptionists with plans starting at $245 per month as of October 2026.
Virtual receptionist companies: a step beyond message taking. Smith.ai, for example, offers human virtual receptionists with per-call pricing, where costs depend on the needs you select.
AI receptionist services: automated systems answer calls using your saved business information. Smith.ai offers a separate AI receptionist product with on-demand escalation to its live agent network. AllDayDesk, the service on this site, is an AI receptionist that answers around the clock using your business details.
Industry-specific services: some companies focus on one field, such as legal intake or property management, with scripts shaped to that trade.

What Answering Services Cost

Pricing varies a lot between companies, and a starting price rarely tells the whole story. Some services charge a flat monthly fee with a set number of included minutes or calls, then bill extra beyond that. Others charge per call or per minute with no monthly base.

A few real examples from company pricing pages: Ruby's human virtual receptionist plans start at $245 per month, checked October 9, 2026. Smith.ai's human receptionist service uses per-call pricing that depends on your selected needs. Always ask what's included in the base amount, what overage charges look like, and whether there's a contract.

AllDayDesk uses simple monthly plans with included minutes and a per-minute rate beyond them; current pricing is displayed separately on this site.

Ask whether pricing is per minute, per call, or a flat monthly rate
Ask how many minutes or calls are included and what overages cost
Ask about setup fees, contract length, and cancellation terms
Compare coverage hours, and ask whether extended-hours or around-the-clock coverage affects the price

How to Compare and Choose a Company

Before signing up with any answering service company, work through a short checklist. The goal is to know exactly what happens to each call and what you'll pay for it.

Coverage: confirm which hours the service answers, and whether after-hours and weekend coverage costs extra
Message handling: ask how and when messages reach you, and whether you can see transcripts and call summaries
Booking: if you want appointments taken, ask which calendar the service books into and what setup it needs
Transfers: ask how call transfers work, what destination and rules you must configure, and whether pickup is guaranteed (it usually isn't)
Unknown answers: a good service takes a message when it doesn't know an answer, a price, or an opening rather than guessing
Trial or sample: listen to a sample of how your calls would sound before committing

How Setup Works

Setup with most answering service companies follows the same pattern. First, you provide your business information so the service can answer accurately. Then you forward your phone number to the service, which keeps your public number unchanged.

With AllDayDesk, you choose your business or enter its website, check the details it pulled together, hear a personalized sample call, and then pick your phone setup. Forwarding instructions depend on your phone provider. For example, Verizon mobile uses *72 plus the destination for all-call forwarding and *71 for unanswered calls, while T-Mobile uses codes like **21*1 followed by the destination for unconditional forwarding. Spectrum Business Voice manages forwarding through its online portal instead of star codes. Because every carrier and product differs, always confirm the exact steps for your specific service.

One important exception: Google Voice does not support forwarding calls from a Google Voice number to an automated system, so Google Voice customers need a different approach.

Where AllDayDesk Fits

AllDayDesk is an AI receptionist service, which puts it in the automated branch of the answering service category. It answers calls around the clock using the business information you save, takes messages when it doesn't know an answer or a price, and shows calls, transcripts, summaries, and bookings in your dashboard.

New appointments are booked into the built-in AllDayDesk dashboard calendar by default, once you've configured your services and availability. If you prefer, you can optionally connect Google Calendar in Settings after connecting and authorizing your Google account. Changes to existing appointments come to you as requests to approve, not confirmed changes. Call transfers are available too, but you configure the destination and rules yourself, and pickup isn't guaranteed.

Whether an AI or human service suits you better depends on your call volume, budget, and how complex your calls tend to be. Compare actual quotes and included allowances side by side rather than assuming one type always costs less.
