Virtual Call Attendant: What It Is and How to Set One Up for Your Business

Think of a virtual call attendant as a phone helper that works from the business information you save. When a call comes in, the attendant greets the caller, answers questions it can answer from your saved details, and handles routine requests like booking a new appointment.

It has honest limits. If a caller asks something the attendant does not know, such as a price it has not been given or a question about an existing appointment, it takes a message so you can respond. Changes to existing appointments are passed to you as requests, not confirmed changes, because only you should decide whether to move something already on your schedule.

Everything the attendant handles shows up in your dashboard: calls, transcripts, summaries, and bookings. You can review what happened on each call instead of guessing.

• Greets callers and answers questions using your saved business information
• Books new appointments once you have set up your services and availability
• Takes a message when it does not know an answer or price
• Passes existing-appointment changes to you as requests
• Can transfer calls to you after you configure a transfer destination and rules
• Shows calls, transcripts, summaries, and bookings in your dashboard

You keep your public phone number. The connection happens through call forwarding, which you set up with your phone carrier. The exact steps depend on who provides your phone service, so it is worth identifying your exact product first, since even one carrier can use different steps for wireless, landline, and hosted business products.

There are two main kinds of forwarding. Unconditional forwarding sends all calls to the attendant. Conditional forwarding only sends calls you cannot take, such as when your line is busy or you do not answer after a few rings. Conditional forwarding is how many owners keep answering their own phone during work hours and let the attendant handle the rest. Not every line or plan supports every forwarding type, so check with your provider before relying on it.

A few verified examples show how much the steps vary. On Verizon mobile, dialing *72 plus the ten-digit destination activates all-call forwarding, *71 handles unanswered calls, and *73 turns it off; setup must be done from the phone while in Verizon coverage. On T-Mobile, **21*1 followed by the destination and # enables unconditional forwarding, **61*1 handles no-reply calls, and ##004# resets forwarding to defaults. For AT&T Phone for Business, all calls use *72, no-answer uses *92, and busy uses *90, each followed by the destination and #. Google Voice is a special case: Google explicitly says forwarding calls from a Google Voice number to an automated system is unsupported, so a Google Voice number is not a workable path to this kind of service.

• Unconditional forwarding sends every call to the attendant
• Conditional forwarding sends only busy or unanswered calls
• Verizon mobile: *72 plus destination for all calls, *71 for unanswered, *73 to disable
• T-Mobile: **21*1destination# for all calls, **61*1destination# for no reply, ##004# to reset
• AT&T Phone for Business: *72 all calls, *92 no answer, *90 busy, each with destination and #
• Google Voice numbers cannot be forwarded to an automated system

Setup starts with your business, not your phone. You choose your business or enter its website, then check the details the service found about you. This saved information is what the attendant uses to answer callers, so reviewing it carefully matters more than any technical step.

Next, you hear a personalized sample of how the attendant would sound for your business. This sample is a preview only and does not create a real booking. If the details sound right, you move on to choosing your phone setup, which is where the forwarding steps from the section above come in.

For booking to work, you configure your services and availability first. New appointments then go on the built-in AllDayDesk dashboard calendar by default. If you prefer, you can connect Google Calendar in Settings after connecting and authorizing your account. That Google Calendar connection is the supported external calendar option; other scheduling tools are not part of the service.

• Choose your business or enter its website
• Check and correct the business details the attendant will use
• Hear a personalized sample (no real booking is made)
• Choose your phone setup and forward your number
• Configure services and availability so new appointments can be booked
• Optionally connect Google Calendar in Settings after authorizing your account

A virtual call attendant is one of three common ways to handle business calls. The right choice depends on your call volume, the kinds of questions callers ask, and your budget. The comparison below describes documented features of each option rather than hands-on testing.

An automated attendant like AllDayDesk answers around the clock using your saved business information and books appointments on a dashboard calendar. Human virtual receptionist services, such as Ruby or Smith.ai's receptionist service, use people to answer calls; Ruby advertises plans starting at $245 per month as of October 2026, and Smith.ai uses per-call pricing, so actual costs depend on the quote and what is included. An in-house receptionist is a full employee: according to the Bureau of Labor Statistics, receptionist duties include greeting visitors and office tasks beyond phone answering, so a phone service is not a full replacement for that role.

A practical way to decide: if most of your calls are routine questions, appointment requests, and messages, an automated attendant handles them at a predictable monthly cost. If callers frequently need judgment calls, complex intake, or a human voice for sensitive matters, a human service or staff member may fit better. Some owners use both, answering their own phone when available and letting the attendant cover the rest through conditional forwarding.

• Automated attendant: answers from your saved details, books appointments, fixed monthly plans
• Human virtual receptionist: people answer calls; pricing varies by provider and quote
• In-house receptionist: full employee with duties beyond the phone
• Hybrid approach: answer your own calls and forward only busy or unanswered ones

Call transfers are available, but they are not automatic. You configure a transfer destination and the rules for when transfers happen. Once configured, the attendant can send a caller to you, but neither that you will pick up nor that the transfer connects instantly is guaranteed, so transfers work best for situations where reaching you is helpful but not critical.

Message taking is the reliable baseline. When the attendant does not know an answer, a price, or how to handle a request, it takes a message instead of guessing. You see those messages in the dashboard along with the call transcript and summary, so nothing depends on a caller leaving a voicemail on your own line.

• Transfers require you to set a destination and rules first
• Pickup and immediate response on transfers are not guaranteed
• Unknown answers, prices, or requests become messages
• Messages, transcripts, and summaries appear in your dashboard
