Best Phone Answering Service for Small Business

Small businesses generally choose between three kinds of phone coverage. Human virtual receptionist services employ real people who answer your forwarded calls. Companies like Ruby offer live receptionist plans, with a starting price of $245 per month as of October 2026, and Smith.ai offers human receptionists priced per call. AnswerConnect is another provider offering 24/7 live answering by people. These services vary in hours, included minutes or calls, and contract terms, so you need a current quote to compare them fairly.

AI receptionist services use software instead of people. AllDayDesk is an example: it answers calls around the clock using business information you save, takes messages, and can book new appointments on its built-in dashboard calendar once you have configured your services and availability. An optional Google Calendar connection is available in Settings after you connect and authorize your Google account. Smith.ai also sells a separate AI receptionist product with its own escalation features, which is distinct from its human service.

In-house coverage is the third option. A front desk employee handles phones along with greeting visitors and other office tasks, according to the Bureau of Labor Statistics receptionist occupation guide. That means comparing a phone service to an in-house hire is not apples to apples — a service covers calls, not the whole reception role.

• Human virtual receptionists: real people — Ruby's plans start at $245/month as of October 2026; Smith.ai uses per-call pricing
• AI receptionists: software answering around the clock — pricing varies by provider, so get a quote
• In-house staff: full reception duties, not just phones — compare total employment cost against service quotes rather than wages alone
• Some providers, like Smith.ai, sell both a human service and a separate AI product — check which one you are quoting

Marketing pages all sound similar, so judge providers on concrete criteria. Start with how the service handles the calls you cannot answer: does it take a clear message, or can it book appointments? If booking matters, ask what calendar it uses and whether it connects to yours. AllDayDesk, for example, books new appointments on its built-in dashboard calendar by default, with an optional Google Calendar connection you authorize in Settings — and changes to existing appointments come to you as requests, not confirmed changes.

Next, check what happens when the service does not know an answer. A good service takes a message instead of guessing at prices or appointment times. Also ask about transfers: with AllDayDesk, you configure a transfer destination and rules yourself, and neither pickup nor an immediate response is guaranteed — so understand exactly what a provider promises before a call is handed to you.

Finally, look at visibility and setup. You should be able to see calls, transcripts, summaries, and bookings in a dashboard, and setup should not require changing your public phone number. With AllDayDesk you keep your existing number by forwarding calls to the service; the forwarding instructions depend on your phone carrier.

• Message taking when the answer, price, or appointment time is unknown
• Appointment booking: which calendar, and how changes to existing bookings are handled
• Transfer behavior: who you can transfer to, and what is guaranteed
• Dashboard access to calls, transcripts, summaries, and bookings
• Setup: keep your number via call forwarding, and hear a personalized sample before committing
• Pricing structure: monthly minutes, per-call rates, and overage charges

Use these questions to narrow your choice in about ten minutes.

First, count your missed calls for one week. If most come after hours, around-the-clock availability matters more than office-hour coverage. Second, decide whether callers need booking or just messages. A salon or dentist usually wants booking; a contractor may mostly need accurate messages with callback numbers. Third, set a monthly budget including overages, not just the base plan. Fourth, test the fit: AllDayDesk lets you enter your business or website, check the details it learned, and hear a personalized sample call before you choose phone setup — and the sample creates no real booking. Fifth, confirm your phone service supports forwarding to an outside number, since that is how you keep your existing number.

• When do most of your missed calls come in?
• Do callers need to book, or just leave a message?
• What is your true monthly budget with overage rates included?
• Can you hear a sample of how your business will be represented before paying?
• Does your phone carrier support the forwarding you need?

Answering services like AllDayDesk work by forwarding your existing number, so carrier support is a real selection criterion. The exact steps depend on your provider and product, and they differ between mobile and business landline services even from the same company.

Examples from official carrier documentation: Verizon mobile uses *72 plus the destination for all-call forwarding and *71 for unanswered calls, while Verizon business landline uses *72 and *73. T-Mobile uses codes like **21*1 plus the destination for unconditional forwarding. AT&T Phone for Business uses *72 for all calls, *92 for no-answer, and *90 for busy — but AT&T Collaborate uses different codes, so you must identify your exact product first. Spectrum Business Voice manages forwarding through the SpectrumBusiness.net portal rather than star codes, and Google Voice explicitly does not support forwarding calls from a Google Voice number to an automated system.

If you are unsure which product you have, check your bill or your provider's support site before choosing a service that depends on a specific forwarding type. Conditional forwarding (busy or no-answer only) is not supported on every plan, so verify with your carrier rather than assuming.

• Verizon mobile: *72 + destination (all calls), *71 (unanswered), *73 to disable
• T-Mobile: **21*1 + destination + # (unconditional), ##004# to reset
• AT&T Phone for Business: *72 all calls, *92 no-answer, *90 busy — Collaborate codes differ
• Spectrum Business Voice: managed in the online portal, not with star codes
• Google Voice numbers: forwarding to an automated system is unsupported

AllDayDesk is this site's own product, so weigh it against the other options with that in mind. It is an AI receptionist that answers calls around the clock using the business information you save. Setup involves choosing your business or entering its website, checking the details it learned, hearing a personalized sample, and choosing how to connect your phone. You keep your public number by forwarding calls, with instructions that depend on your phone service.

Once running, calls, transcripts, summaries, and bookings appear in your dashboard. New appointments go on the built-in AllDayDesk calendar by default after you configure services and availability, with an optional Google Calendar connection in Settings. When the service does not know an answer or a price, it takes a message for you. Pricing is displayed separately on the pricing page rather than baked into this guide.

• Answers calls around the clock using your saved business information
• Books new appointments once services and availability are configured
• Optional Google Calendar connection, authorized by you in Settings
• Takes a message when an answer or price is unknown
• Keeps your existing number through call forwarding
