Receptionist System: What It Is and How to Set One Up

At its core, a receptionist system sits between your caller and you. A call comes in to your normal business number, and instead of ringing through to you, it is answered by a person, an automated attendant, or an AI receptionist. The system greets the caller, answers basic questions using information you provide, collects messages, and in some cases books appointments directly.

It is worth separating this from a full front-desk job. According to the Bureau of Labor Statistics, in-house receptionists also greet visitors and handle office tasks beyond the phone, so a phone answering system covers only the call-handling part of that role.

For most solo owners and small teams, the goal is narrower: callers reach a helpful voice at any hour, real questions get answered or turned into messages, and appointment requests land somewhere you can actually see them.

• Answers your existing business number so you keep it
• Greets callers and answers questions from your saved business details
• Takes messages when an answer, price, or opening is unknown
• Can book new appointments into a calendar you control
• Shows you calls, transcripts, summaries, and bookings in a dashboard

This comparison covers documented features from each provider's own materials, not hands-on testing. AllDayDesk, the AI receptionist described on this site, is included so you can see how it stacks up.

A human virtual receptionist service staffs your calls with trained people. Ruby advertises plans starting at $245 per month as of October 2026, and Smith.ai prices its human receptionist service per call, with the total depending on the needs you select. Starting prices are not the whole story: you still need to check included minutes or calls, overage rates, coverage hours, and contract terms on a current quote.

An AI receptionist answers calls with software using your saved business information. AllDayDesk answers around the clock, keeps your public number through call forwarding, books new appointments into its built-in dashboard calendar by default, and supports an optional Google Calendar connection in Settings after you connect and authorize your account. When it does not know an answer, a price, or an opening, it takes a message. Human coverage and fees vary by service and plan, so neither option is automatically cheaper; compare quotes side by side.

• In-house receptionist: full scope including visitors and office tasks, but salary, training, and limited hours
• Human virtual receptionist: real people on your calls; Ruby lists plans from $245/month, Smith.ai uses per-call pricing
• AI receptionist like AllDayDesk: software answers around the clock using your business details, with a dashboard for calls, transcripts, summaries, and bookings
• Smith.ai also sells a separate AI receptionist product with escalation to its own live agents; that is their feature, not AllDayDesk's
• Ask every provider for included usage, overage rates, hours covered, and contract length before deciding

Most receptionist systems, including AllDayDesk, do not require you to change your phone number. You keep your public number and forward calls to the service. The exact steps depend on your phone provider, so identify your exact product first (for example, Verizon wireless is different from Verizon business landline, and Comcast has several voice products).

Some verified examples of all-call forwarding: Verizon mobile uses *72 plus the 10-digit destination, with *73 to turn it off, and *71 for unanswered calls. T-Mobile uses **21*1 followed by the destination and # for unconditional forwarding, with ##21# to disable. AT&T Phone for Business uses *72, destination, # for all calls, *92 for no-answer, and *90 for busy. Spectrum Business Voice manages forwarding through the SpectrumBusiness.net portal under Voice Settings or Forwarding Manager rather than star codes. Vonage Business Communications enables forwarding to a phone number from its Call Forwarding setting.

One important limit: Google Voice explicitly does not support forwarding calls from a Google Voice number to an automated system, so a Google Voice line is not a compatible path to an AI receptionist. If your provider is not listed here, check their support pages for your exact service before trying any code, and verify the forwarding worked by placing a test call from another phone.

• Verizon mobile: *72 + destination to forward all calls, *71 for unanswered, *73 to disable
• T-Mobile: **21*1 + destination + # (all calls), ##21# to disable, ##004# resets to defaults
• AT&T Phone for Business: *72, destination, # (all calls); *92 no-answer; *90 busy
• Comcast, Spectrum, Vonage, and Frontier business products are usually managed in an online portal or app, not with codes
• Forwarding applies to calls, not texts, on mobile carriers, and plan charges may apply
• Always confirm your exact product name before using any code or portal step

Setup starts by choosing your business or entering its website so AllDayDesk can pull in your details. You then check that the information is accurate, hear a personalized sample of how your receptionist would sound, and choose your phone setup method. The sample is a preview only; it does not create a real booking.

After that, you keep your public number by forwarding calls to AllDayDesk, using the instructions that match your phone service. Once you have configured your services and availability, new appointments are booked into the built-in AllDayDesk dashboard calendar by default. If you prefer Google Calendar, you can optionally connect and authorize your Google account in Settings.

Everything the receptionist does is visible to you: calls, transcripts, summaries, and bookings appear in your dashboard. Changes to existing appointments are passed to you as requests, not confirmed changes, so you stay in control of your schedule. Transfers to you are also something you configure yourself, with a destination and rules; a transfer is not guaranteed to be picked up or answered immediately.

• Choose your business or enter its website to load your details
• Review the details, listen to a personalized sample, and pick your phone setup
• Forward your existing number using your provider's steps
• Configure services and availability so new bookings can be made
• Optionally connect Google Calendar in Settings after authorizing your account
• Review calls, transcripts, summaries, and bookings in the dashboard

Start with your call volume and hours. If you work alone and most calls arrive while you are on a job site, an around-the-clock automated option covers the gaps. If your callers ask complex questions that need judgment, or you want a human voice on every call, a human service fits better, at a higher and usage-dependent price.

Next, check compatibility before you commit. Confirm your phone provider supports forwarding to an outside number, and know whether you want all calls forwarded or only missed ones. Remember that Google Voice numbers cannot be forwarded to an automated system.

Finally, look at what happens after the call. Ask where bookings land, whether you can see transcripts, and how messages reach you. A system that answers calls but hides the results from you creates more work, not less.

• Count your typical weekly calls and when they come in
• Decide between forwarding all calls versus only unanswered ones
• Confirm your provider and exact product support forwarding
• Compare total monthly cost at your real call volume, including overages
• Check where appointments and messages end up and whether you can review transcripts
