Best Telephone Answering Service: A Practical Guide to Choosing One

When people search for the best telephone answering service, they usually run into three categories. Knowing which one you need narrows the field fast.

Human answering services employ trained receptionists who answer your calls from a call center. They can hold a real conversation, use judgment on unusual questions, and follow scripts you provide. AnswerConnect, for example, advertises 24/7 live business answering by people, and Ruby offers human virtual receptionists with plans starting at $245 per month as of October 2026. Smith.ai uses per-call pricing for its human receptionist service, so the total depends on your call count.

AI answering services use software to answer calls, answer questions from your business information, take messages, and book appointments. AllDayDesk is in this category. AI services can handle calls at any hour, and many publish flat monthly plans, but they are not a person, so complex or unusual requests may end up as a message for you rather than a full resolution. Compare actual quotes, since pricing varies by provider.

Hybrid services combine both. Smith.ai, for instance, offers a separate AI receptionist product with on-demand escalation to its live agent network. If you want software handling routine calls with people available for exceptions, look at this category.

• Human services: strongest judgment and conversational flexibility, with pricing that varies by provider
• AI services: around-the-clock availability, best for routine questions, messages, and booking
• Hybrid services: AI first with human backup for exceptions

Pricing models matter more than the headline number. Most services use one of three structures: a flat monthly rate with included minutes or calls, per-call pricing, or per-minute pricing with overage charges.

To compare fairly, estimate your monthly call volume and average call length, then calculate what each provider would actually charge at that volume. A plan that looks cheap per call can get expensive if your calls run long, and a per-minute plan can surprise you if callers leave detailed messages.

Pricing differs by provider and structure. Ruby's advertised starting price is $245 per month, and Smith.ai prices its human service per call, so you need a quote to know your real cost. AI services like AllDayDesk publish flat monthly plans with included minutes. Our own pricing is shown separately on this page — it is not written into this guide so it stays current.

For a fuller breakdown of pricing structures and what drives cost, see our dedicated guide.

• Flat monthly with included minutes: predictable, watch overage rates
• Per-call: simple, but heavy call months cost more
• Per-minute: fair for short calls, risky for long ones
• Always ask what is included: message delivery, booking, and transfer features are not universal

Use this checklist when evaluating any provider, including us. It is an original decision framework, not a ranking.

Start with coverage: do you need after-hours and weekend answering, or only overflow during business hours? Then check how the service handles what it does not know — a good service takes a message rather than guessing at a price or an appointment slot. Ask how appointments are booked, whether the service can transfer calls to you, and what rules control those transfers. Ask for a sample call or demo in your own business context. Finally, read the contract: minimum terms, overage rates, and how you get your recordings or messages if you leave.

• Coverage hours that match when your customers actually call
• Clear behavior when the service does not know an answer: take a message, never invent one
• Appointment booking that fits your calendar setup
• Call transfer options with rules you control
• A personalized demo before you commit
• Transparent pricing with published overage rates
• Easy access to your call records, transcripts, and messages

Almost every answering service works by forwarding your existing number to the service, so you keep your public phone number. The forwarding instructions depend on your phone carrier, and they differ between mobile and business landline products — even within the same company.

For example, Verizon mobile uses *72 plus the destination number for all-call forwarding and *71 for unanswered calls, while Verizon business landlines use *72 and *73 to activate and deactivate. T-Mobile uses **21*1 codes for unconditional forwarding and **61*1 for no-reply. Spectrum Business Voice manages forwarding through its web portal rather than star codes. The lesson: identify your exact service and product before entering any code, and confirm with your carrier if you are unsure.

One known limitation: Google Voice explicitly does not support forwarding calls from a Google Voice number to an automated system, so a Voice number is not a compatible path to an AI answering service.

• You keep your existing business number; forwarding sends calls to the service
• Carrier codes vary by product — wireless and business landline instructions differ
• Confirm your exact service name with your carrier before activating

AllDayDesk is this site's own product: an AI receptionist that answers calls around the clock using business information you save. Setup involves choosing your business or entering its website, checking the details it pulls in, hearing a personalized sample, and choosing how to forward your phone. The sample call creates no real booking — it just shows you how the receptionist would sound.

Calls, transcripts, summaries, and bookings appear in your dashboard. New appointments go to the built-in AllDayDesk calendar by default once you have configured your services and availability, and an optional Google Calendar connection is available in Settings after you connect and authorize your account. Changes to existing appointments come to you as requests, not confirmed edits. When the receptionist does not know an answer, a price, or an open slot, it takes a message instead of guessing.

Compared with the human services above, the tradeoff is straightforward: around-the-clock availability in exchange for software rather than a person on the line. If your calls are mostly routine — hours, services, pricing you have published, and booking — that tradeoff often works well. If callers frequently have complex situations needing judgment, a human or hybrid service may fit better.

• AI receptionist answering with your saved business details
• Dashboard with calls, transcripts, summaries, and bookings
• Built-in calendar by default; optional Google Calendar connection in Settings
• Unknown answers become messages for you, not guesses
