Virtual Receptionist Phone System: How It Works and How to Set One Up

A virtual receptionist phone system has two layers. The receptionist layer is the service that answers, gathers caller information, and books appointments. The phone-system layer is the plumbing that routes calls from your existing business number to that service. You do not usually replace your phone carrier; you add forwarding on top of it.

This is different from an in-house receptionist. A front-desk employee handles visitors, mail, and office tasks in addition to phones, so a phone service is not a full replacement for that role. It covers the answering part of the job, including times when nobody in the office can pick up.

It is also different from a plain auto attendant. An auto attendant plays a menu and routes calls, but it does not hold a conversation or book appointments. A virtual receptionist talks with callers, answers questions from your saved business information, and takes a message when it does not know an answer, a price, or an available time.

• Callers dial your existing business number; forwarding sends the call to the receptionist.
• The receptionist answers using your saved business details and speaks in a personalized style you preview as a sample before going live.
• When an answer, price, or appointment time is unknown, the receptionist takes a message instead of guessing.
• Calls, transcripts, summaries, and bookings appear in your dashboard so you can review everything.

Forwarding is the step that connects your number to the receptionist. Most owners keep their public number and forward calls to the new service, so customers never see a different number. The instructions depend entirely on your phone provider, so identify your exact service before looking up steps. A wireless plan, a business landline, and a hosted VoIP product from the same company can all use different methods.

Some providers use star codes dialed from the phone itself. For example, Verizon mobile uses *72 plus the destination for all-call forwarding and *71 for unanswered calls, with *73 to turn forwarding off, and these must be set from the phone while in Verizon coverage. Verizon business landline also uses *72 and *73 for all-call forwarding. AT&T Phone for Business uses *72 with a destination and # for all calls, *92 for no-answer, and *90 for busy, while AT&T Collaborate uses a different set (*62 for busy, *92 for no-answer). Optimum Business Phone uses *72 and *73, and Comcast Managed Voice on the Panasonic TPA65 uses *72, *92, and *90 in the same style.

Other providers manage forwarding in a web portal instead. Spectrum Business Voice forwarding is set in SpectrumBusiness.net under Voice Settings or Forwarding Manager, where you choose all calls or busy/no-answer and set the destination. Vonage Business Communications has a Call Forwarding option where you enable forwarding to a phone number. Windstream OfficeSuite UC uses the WE Connect dashboard's My Call Forwarding widget, and Frontier Unlimited Digital Voice supports both *72/*73 codes and portal settings under Call Settings.

One important limit: Google Voice can forward calls to linked phone numbers, but Google explicitly states that forwarding calls from a Google Voice number to an automated system is unsupported. If your business runs on Google Voice, check with the service about options rather than assuming forwarding will work.

• Identify your exact product first: wireless, business landline, and hosted VoIP from the same carrier often use different steps.
• Star-code carriers include Verizon mobile (*72/*71/*73), Verizon business landline (*72/*73), AT&T Phone for Business (*72/*92/*90), AT&T Collaborate (*72/*62/*92), Optimum Business Phone (*72/*73), and Comcast Managed Voice (*72/*92/*90).
• Portal-based carriers include Spectrum Business Voice, Vonage Business Communications, Windstream OfficeSuite UC, and Frontier Unlimited Digital Voice.
• Conditional forwarding (busy or no-answer only) is a separate feature from unconditional forwarding and is not supported on every plan; confirm with your carrier.
• Google Voice does not support forwarding to automated systems.

Once a call reaches the receptionist, it works from the business information you saved during setup. It can answer general questions about your business, take detailed messages, and book new appointments. Booking uses the built-in AllDayDesk dashboard calendar by default, which works once you have configured your services and availability. If you prefer Google Calendar, you can connect and authorize your Google account in Settings as an optional step.

There are honest limits to know about. Changes to existing appointments are passed to you as requests rather than confirmed changes, so you stay in control of your schedule. Transfers to you are possible, but only after you configure a destination and rules for them, and neither that the caller will be picked up nor an immediate response is guaranteed. The receptionist never guesses: when it does not know an answer, a price, or an opening, it takes a message so you can follow up.

Everything is reviewable. Each call leaves a transcript and a summary in your dashboard, along with any booking or message, so you can see exactly what happened without listening to recordings.

• Answers questions using your saved business information and takes a message when something is unknown.
• Books new appointments on the built-in dashboard calendar once services and availability are configured.
• Optional Google Calendar connection is available in Settings after you connect and authorize your account.
• Changes to existing appointments arrive as requests for you, not automatic confirmed changes.
• Transfers require you to set a destination and rules in advance; pickup is not guaranteed.

The biggest choice is between human receptionists and software-based ones. Human services, such as Ruby's live receptionist plans starting at $245 per month as of October 2026, or Smith.ai's per-call human receptionist pricing, put trained people on your calls. Software options like AllDayDesk use an AI receptionist with around-the-clock availability. Human coverage and fees vary by service and plan, so compare current quotes on included minutes or calls, overage charges, hours covered, and contract terms rather than relying on a starting price alone.

For the phone-system layer, check three things before signing up. First, confirm your carrier supports forwarding to an outside number and find its exact instructions, since a wireless plan and a business landline from the same company can differ. Second, decide whether you want all calls forwarded or only missed ones, because conditional forwarding is a separate feature that not every plan includes. Third, confirm how appointments will be recorded, whether that is a built-in calendar or an optional Google Calendar connection.

A practical way to compare: list the call situations you actually face, such as after-hours calls, busy-line calls, and questions about pricing. Then check how each service handles each situation, what it does when it does not know an answer, and what you pay for the minutes those calls will use.

• Human services (Ruby from $245/month as of October 2026; Smith.ai per-call pricing) versus software receptionists: compare scope, not just price.
• Verify your carrier's forwarding support and exact product name before committing.
• Decide between unconditional forwarding (all calls) and conditional forwarding (busy or no-answer only).
• Compare included minutes, overage rates, and what happens when a call runs long.
• Check how each service records appointments and what it does with unknown answers.

Setup starts online, not with new hardware. You choose your business from a list or enter its website, and AllDayDesk checks the business details it finds. You then hear a personalized sample of how your calls would be answered, which lets you correct any wrong information before going live. Remember that the sample is a demonstration and creates no real booking.

Next, you choose your phone setup option. Because forwarding instructions depend on your phone service, follow the steps for your specific carrier. For example, on Verizon mobile you dial *72 plus the ten-digit destination to forward all calls and *73 to turn it off, while Spectrum Business Voice customers enable forwarding in the online portal. If your carrier offers both all-call and no-answer forwarding, pick based on whether you want the receptionist to handle every call or only the ones you miss.

Once forwarding is active, configure your services and availability so new bookings land on the built-in dashboard calendar, and connect Google Calendar in Settings if you want that optional connection. From then on, check the dashboard for calls, transcripts, summaries, and booking requests so you can confirm calls are coming through the way you expect.

• Choose your business or enter its website and review the details the service finds.
• Listen to the personalized sample and fix any incorrect business information; the sample makes no real booking.
• Choose phone setup and follow your carrier's exact forwarding steps.
• Set services and availability so bookings land on the built-in calendar.
• Optionally connect and authorize Google Calendar in Settings, then review calls and transcripts in the dashboard.
