Automated Phone Answering Machine: What It Is and How to Set One Up
An automated phone answering machine is a system that picks up your business line when you cannot, listens to the caller, and handles the call without a person on your end. Traditional machines just record a message. Modern automated systems use recorded or computer-generated voices that can greet callers, answer common questions, and take messages you can read later. This guide explains how these systems work, how they compare to plain voicemail and human answering services, and how to connect one to your existing business number using call forwarding.

What an automated phone answering machine does
A basic answering machine plays one greeting and records whatever the caller says. An automated phone answering machine goes further: it answers the call automatically, speaks with the caller, and can collect details like the caller's name, number, and reason for calling. Some systems can also answer simple questions, such as your business hours, using information the owner has saved ahead of time.
The key difference is that the machine is interactive. Instead of a caller talking into a void and hoping you check the tape, the system responds in real time, asks follow-up questions when needed, and organizes what it heard so you can review it later. AllDayDesk is one example: it answers calls around the clock using your saved business information, and you can read calls, transcripts, summaries, and booked appointments in a dashboard.
- Answers automatically when you cannot pick up
- Greets the caller and finds out why they called
- Answers simple questions from saved business details
- Takes a message when it does not know an answer, price, or opening
- Shows you calls, transcripts, and summaries afterward

Automated machine, voicemail, or answering service
There are three common ways to handle calls you miss, and each works differently. Plain voicemail is the simplest: a greeting plays, the caller leaves a message, and that is all. An automated answering machine adds interaction, so callers get answers to basic questions and better-organized messages. A live answering service puts real people on the line, which helps with judgment calls. Pricing varies by provider and plan: Ruby advertises live virtual receptionist plans starting at $245 per month as of October 2026, and Smith.ai prices its human receptionist service per call, so exact costs depend on the quote and included usage.
The right choice depends on your call volume and how complicated your calls are. If most callers just want hours, directions, or to leave a message, an automated system handles that well. If callers often need nuanced answers or you want a person's judgment on every call, compare the trade-offs in the AI receptionist versus human receptionist guide. Note that in-house receptionists also do office work beyond the phone, so a phone service is not a full replacement for one.
- Voicemail: records only, no interaction
- Automated machine: interactive, answers basic questions from saved details
- Live answering service: real people, better judgment on nuanced calls
- Coverage and fees vary by provider and plan, so compare current quotes

How to connect one to your existing number
You do not need a new phone number. You can keep your public number and forward calls to the automated system using your phone carrier's call forwarding feature. The exact steps depend on your carrier and product, so identify which service you have before entering any codes.
As examples of verified instructions: Verizon mobile customers activate all-call forwarding by dialing *72 plus the 10-digit destination and turn it off with *73, set up from the phone while in Verizon coverage. T-Mobile uses **21*1 followed by the destination and # for unconditional forwarding, with ##21# to disable. For Optimum Business Phone, dial *72, wait for dial tone, then dial the destination; *73 turns it off. Spectrum Business Voice manages forwarding through the SpectrumBusiness.net portal under Voice Settings or Forwarding Manager rather than star codes. Many other carriers, including Frontier, Vonage, Comcast Business, and AT&T business products, support forwarding, but the steps differ by product, so check your carrier's guide for your exact service.
One important exception: Google Voice does not support forwarding calls from a Google Voice number to an automated system, so that path will not work. If your carrier is not listed here, call its support line and ask whether call forwarding to an outside number is available on your plan.
- Verizon mobile: *72 + destination to turn on, *73 to turn off
- T-Mobile: **21*1 + destination + # to turn on, ##21# to turn off
- Optimum Business Phone: *72, dial tone, destination; *73 to disable
- Spectrum Business Voice: portal-based, no star codes
- Google Voice numbers cannot forward to automated systems

Setting up an automated answering machine with AllDayDesk
With AllDayDesk, setup starts by choosing your business or entering its website so the system can pull in your details. You then check that the information is correct, listen to a personalized sample call so you can hear how your receptionist sounds, and choose your phone setup. The sample is a demonstration only and does not create a real booking.
After that, callers who reach the system get answers based on your saved business information. When the system does not know an answer, a price, or an available appointment, it takes a message instead of guessing. If you want it to book appointments, you configure your services and availability first; new appointments then go on the built-in AllDayDesk dashboard calendar by default. If you prefer Google Calendar, you can optionally connect and authorize your Google account in Settings.
Keep in mind that changes to existing appointments are passed to you as requests rather than confirmed changes, and call transfers to you require you to set up a destination and rules in advance. Transfers are not guaranteed to connect or to be answered immediately, so review your settings carefully.
- Choose your business or enter its website
- Review and correct the pulled-in details
- Listen to a personalized sample (no real booking is made)
- Choose your phone setup and forward your number
- Configure services and availability to enable booking
- Optionally connect Google Calendar in Settings
- For the full setup process from start to finish, follow the setup guide. how to set up a call answering service

How to decide if an automated machine fits your business
Ask yourself a few practical questions before choosing. First, what do callers actually ask for? If the answers come from a short list of facts you can write down, such as hours, location, or service descriptions, an automated system handles them well. Second, how often are you unavailable? If you answer your own phone during the day, an automated system is an option for evenings, weekends, or times when you are simply busy on another call or a job site.
Third, what should happen when the machine cannot help? A good setup takes a clear message with the caller's name, number, and reason for calling, so you can call back with the right information. Finally, check the practical details: whether your carrier supports forwarding on your plan, what the service costs including any per-minute overages, and how you will review messages and bookings. AllDayDesk shows calls, transcripts, summaries, and bookings in its dashboard, so plan a few minutes each day to check it.
- List the questions callers ask most and whether you can write down the answers

More questions, answered
Do I have to change my business phone number?
No. You keep your public number and use your carrier's call forwarding feature to send calls to the automated system. The forwarding steps depend on your carrier and the exact service you have.
Will callers know they are talking to an automated system?
The system answers with a greeting in its own voice, so callers will hear that it is not a person on your end. You can listen to a personalized sample during setup to hear exactly how your calls would sound.
What happens if the machine does not know the answer?
When an answer, price, or appointment opening is unknown, the system takes a message with the caller's details so you can follow up yourself. It does not guess.
Can it book appointments on my calendar?
Yes, once you have configured your services and availability. New appointments go on the built-in AllDayDesk dashboard calendar by default, and you can optionally connect Google Calendar in Settings after authorizing your account.
Can calls be transferred to me?
Transfers are possible, but you must configure a destination and rules first. Neither pickup nor an immediate response is guaranteed, so treat transfers as one tool rather than a certainty.
Does an automated machine replace a receptionist?
It handles phone calls, but an in-house receptionist also greets visitors and does other office tasks. Compare the scope of each option rather than treating a phone service as a full employee replacement.
