# AI Answering Service: Set Up Your Own Phone First, Then Upgrade > Build a basic AI answering service with the phone you have: greeting, after-hours voicemail, transcripts, call screening. Then see where it stops. _Source: https://professionalstoolkit.com/articles/ai-answering-service — The Professional's Toolkit · updated November 2026_ _Part of: [Get every business call answered, even when nobody can pick up](https://professionalstoolkit.com/solutions/answer-calls-with-ai) — the guide, the do-it-yourself version and the tools that do it_ --- An AI answering service picks up when you can't: it greets the caller, answers routine questions, takes a message or books a slot, and tells you what happened. Before you sign up for one, set up the phone you already have. A greeting that answers the top three questions, calls sent to voicemail on a schedule, and transcripts in your inbox cover a real share of that job with tools you already own. Below are the exact steps, then the point where a message-taker is no longer enough. **1 week** — of logged missed calls tells you whether a greeting and voicemail are enough - **3 min** — longest greeting Google Voice records in Chrome or Firefox - **4 jobs** — on every call: greet, answer, capture, act - **6 columns** — in the call log that shows what voicemail misses ## What an AI answering service does that voicemail cannot Every answered call has four jobs: greet, answer, capture, act. Voicemail handles the first and the third. The built-in tools on a modern phone add two more pieces, screening and transcription. What stays missing is the conversation in the middle, where the caller asks something and gets a reply drawn from your own information, and the action at the end, such as a booked slot. People searching for a *free AI receptionist* should know that up front. The setup in this guide is an answering machine with good manners. It is not a receptionist. If you first want the full picture of the category, read [what an AI receptionist is and how it works](/articles/ai-receptionist), then come back for the steps. | Job on the call | Phone you already have | AI phone answering service | |---|---|---| | Greet | Recorded greeting | Spoken greeting, live | | Answer questions | Only what the greeting says | From the information you give it | | Capture | Voicemail and transcript | Name, reason, contact details | | Act | Nothing | Booking, confirmation, summary | ## Record a greeting that answers the top three questions Most callers want one of three things: your hours, where you work, and how to book. Put all three in the greeting and a share of callers will hang up satisfied. In Google Voice you can record several greetings and pick the active one, so keep a daytime version and a closed version. A greeting recorded in Chrome or Firefox can run three minutes; in Safari the cap is one minute.[1] 1. On a computer, go to voice.google.com. 2. At the top right, click **Settings**. 3. On the left, click **Voicemail**. 4. In the Active greeting section, click **Record a greeting**. 5. Click **Record**, say your script, then click **Stop**. 6. Click **Save**, name the greeting, and click **Save** again. To switch later, open **Manage all greetings** in the same section and choose **Set as active** next to the one you want. Your browser has to allow Google Voice to use the microphone first. > 💡 **Script the greeting in three lines:** Line one: who you are and your hours. Line two: where you work or your service area. Line three: how to book, plus what to say in a message (name, number, reason). ## Send after-hours calls to voicemail on a schedule A phone that rings at 9 p.m. trains you to ignore it. Send those calls straight to the greeting instead. In Google Voice, open **Settings**, click **Do not disturb**, and turn on **Send calls to voicemail**. You can flip it on and off at any time, and texts to the number are not affected.[2] The automatic version depends on the account type. Google says the option to follow your Calendar working hours is available with Voice for Google Workspace accounts managed by a work or school. With it, calls go to voicemail whenever Calendar shows you are not working. On other accounts the switch is manual. Make it a closing-time habit. If your business number lives with a mobile carrier or a landline provider, look for conditional call forwarding in that provider's help pages. It forwards a call only when you do not answer or the line is busy. The codes and menus differ by carrier, so follow theirs and test from a second phone. ## Read your messages as text, not audio Listening to eight voicemails in a row takes time you do not have. Reading them takes a minute. Google Voice can forward voicemail transcripts so they show up in your email app: go to voice.google.com, click **Settings**, click **Voicemail**, and turn on **Get voicemail via email**.[3] Two details help you plan. Google says a voicemail can run three minutes, and there is no limit on how many you can receive. Treat each transcript as a draft, though. Phone numbers, street names and surnames are where transcription slips, so play the audio before you call someone back or write an address into a job sheet. > ⚠ **Transcripts get numbers wrong:** Play the audio before you dial back or copy an address. A single wrong digit in a callback number loses the customer. ## Let the iPhone ask unknown callers why they are calling Apple's Call Screening answers calls from unknown numbers without interrupting you. The caller shares a name and a reason, then your iPhone rings and shows the response so you can decide whether to pick up.[4] 1. Open the **Settings** app. 2. Tap **Apps**, then tap **Phone**. 3. Choose **Ask Reason for Calling**. The other two choices are **Never**, which leaves screening off, and **Silence**, which sends unsaved numbers to voicemail. Apple notes that Siri speaks in the iPhone's default language when it answers. Think before you turn this on for a business line. A new customer is an unknown number by definition, so every first-time caller meets the screening prompt before a person. That suits a solo consultant who gets a lot of sales calls. It fits less well when most of your calls are strangers who want to book. > 💡 **Save your regulars as contacts:** Call Screening only steps in for unknown numbers. Suppliers, repeat customers and staff saved in Contacts ring through as usual. ## One week with a call log: a two-person plumbing shop Here is an illustration of how the setup pays off. Two plumbers share one number and miss calls whenever both are under a sink. They record a closed greeting and a daytime greeting, turn on email transcripts, and start a Google Sheet with six columns: date, caller, reason, answered by the greeting, wanted to book, called back within an hour. After a week the log shows twenty-three missed calls. Nine callers only wanted hours or the service area, and the greeting handled them. Eight wanted an appointment and left a message. Six were something else. The useful number is the last column: of the eight who wanted to book, three had hired another plumber by the time the callback came. That is the cost of a message-taker, written down. Your numbers will differ. The method holds. Log one week, sort the reasons, and you will know whether the greeting is enough or whether callers need an answer on the spot. ## Signs you have outgrown voicemail and need an AI phone answering system The free setup breaks at three specific points. It cannot answer a question the greeting did not predict. It cannot book, so every appointment waits for a callback. And nothing from the call lands in your calendar or customer list unless you type it. For a shop that misses a handful of calls and returns them within the hour, that is fine. Once the log shows bookings lost to slow callbacks, **AI call answering** starts to earn its place. For a small business that wants a receptionist without building anything, Lindy [answers its own number as a receptionist](/articles/lindy-phone-agent). It suits owners who already live in a calendar and a booking link and want the phone to feed both. Plan how callers will reach that number before you print it anywhere. ### Lindy — A receptionist line without building anything Lindy's phone line answers its own number as a receptionist: it takes the caller's name, reason and contact details, books through a booking link you choose, answers from the information you give it, texts confirmations and sends you a summary. 1. Give it your hours, services and booking link 2. Call the number yourself and try real questions 3. Read the summaries for the first week - Where it stops: Anything outside the information you gave becomes a message. Pausing the line does not stop the number's monthly fee. - Plan: A paid plan (Plus, Pro, Max or Enterprise); the number is billed separately - [Receptionist setup, step by step](https://professionalstoolkit.com/articles/lindy-phone-agent) · [Lindy](https://professionalstoolkit.com/tools/lindy) Teams that already run a chat agent on their website sit in a different spot. If the same agent, with the same knowledge, should also speak on the phone, a voice channel on that platform keeps one brain for both. It is a build project, and it belongs with someone comfortable in a visual builder. ### Botpress — Voice added to an existing chat agent Voice is one more channel of a Botpress agent, connected through its Twilio integration: callers talk to the bot on a Twilio number, and it draws on the agent and knowledge you build in Studio. - Where it stops: You build the agent and its knowledge yourself, and the voice channel is listed only on the Enterprise plan. - Plan: Enterprise - [Botpress](https://professionalstoolkit.com/tools/botpress) Your week of logging is the setup material for either one. The reasons column becomes the list of questions the agent must answer, written with the exact answers you would give yourself. The booking requests show which appointment types to offer. The odd calls, such as complaints, urgent jobs or someone asking for a person by name, mark where the agent should stop and take a message for you. Start with that short list. Widen it only after you have read a week of call summaries. Whichever route you take, keep a person in the loop. Lindy's own docs say it can make mistakes and to review its actions, and the same caution applies to any agent that books or quotes. Tell callers at the start that they are talking to an AI, and say that the call is recorded where consent is required. For the full set of parts, from telephony to hand-off, see [how AI voice agents are put together](/articles/ai-voice-agent). ## FAQ **Is a free AI receptionist the same as voicemail with transcripts?** No. Voicemail with transcripts greets and captures, but it cannot hold a conversation, answer from your own information or book a slot. It is the free starting point, and for low call volumes it can be enough. **Does an AI phone answering service need a new phone number?** It depends on the product. Lindy answers on its own number with a US or Canadian area code, and a Botpress voice agent takes calls on a Twilio number. Decide how callers will reach that number before you publish it. **Should callers be told that AI call answering is in use?** Yes. Say in the first sentence that the caller is talking to an AI assistant, and mention that the call is recorded where consent is required. Callers who know what they are talking to leave clearer messages. **Do the Google Voice steps work without an iPhone?** Yes. The greeting, Do not disturb and transcript settings are all changed in a browser at voice.google.com. Only the Call Screening steps are specific to the iPhone. ## Count a week of missed calls before you change anything Record the two greetings today, turn on transcripts, and start the six-column log. Seven days later you will hold the one figure that settles this decision: how many callers wanted something a recording could not give them. If that number is near zero, you are done. If it is not, you now have a list of real questions and booking requests to hand to whichever answering agent you set up next. ## Sources [1] Google Voice Help — https://support.google.com/voice/answer/115069?hl=en (Nov 2026) [2] Google Voice Help — https://support.google.com/voice/answer/115106?hl=en (Nov 2026) [3] Google Voice Help — https://support.google.com/voice/answer/9182115?hl=en (Nov 2026) [4] Apple Support — https://support.apple.com/guide/iphone/screen-and-block-calls-iphe4b3f7823/ios (Nov 2026)
