Inbound Call Answering: A Practical Guide for Small Businesses

Inbound call answering is the receiving side of business phone work: calls come in, someone or something handles them, and you get the result afterward. Handling a call can mean greeting the caller, answering questions about your hours, services, or pricing, taking a detailed message, booking an appointment, or transferring the caller to you when appropriate.

It is different from outbound work like follow-up calls or telemarketing. With inbound answering, the caller always starts the conversation by dialing your number. Your job is to make sure that call lands somewhere useful instead of ringing out into voicemail.

Most owners answer their own phones during the day, so inbound answering usually fills the gaps: times when you are on another call, on a job site, with a customer in person, or simply closed. The setup runs on top of your existing number, so callers never need to learn a new one.

• Callers dial your existing business number; nothing changes on their end.
• The call is routed to an answering setup when you cannot or do not pick up.
• The setup can answer questions, take messages, book appointments, or transfer calls.
• You review calls, transcripts, summaries, and bookings afterward in a dashboard.

You keep your public number by forwarding calls to the answering service. The exact steps depend on your phone provider, so identify your exact service first — wireless, business landline, or hosted voice — because codes and menus differ even within one company.

Some common examples from provider documentation: Verizon mobile uses *72 plus the 10-digit destination to forward all calls, *71 for unanswered calls, and *73 to turn forwarding off; setup must be done from the phone while in Verizon coverage. T-Mobile uses **21*1 followed by the destination and # for unconditional forwarding, with separate codes for no-reply, unreachable, and busy conditions. AT&T Phone for Business uses *72, destination, # for all calls and *92 for no-answer forwarding. AT&T Collaborate also uses *72 plus the destination for always forwarding and *73 to disable, but its conditional codes differ: *62 plus the destination for busy forwarding and *92 plus the destination for no-answer forwarding. Comcast Business supports call forwarding across its phone products, and features like remote call forwarding are managed through My Account or the Comcast Business App — but which controls you get depends on whether you have Voice Mobility, Business Voice, or VoiceEdge, so confirm your exact product before following any instructions.

One important limit: Google Voice explicitly does not support forwarding calls from a Google Voice number to an automated system, so a Google Voice number is not a compatible forwarding source for an AI answering setup.

If your provider does not document conditional forwarding for your exact plan, ask their support team to confirm what your line supports. Unconditional forwarding (all calls) and conditional forwarding (only when busy, unanswered, or unreachable) are different features, and a code that works on one carrier's plan may not exist on another's.

• Identify your exact service name before using any instructions — codes differ between a carrier's wireless, landline, and hosted products.
• Unconditional forwarding sends all calls; conditional forwarding sends only busy, unanswered, or unreachable calls.
• After activating, place a test call from another phone to confirm the destination answers.
• *73 is the common disable code on many landline and wireless plans, but confirm with your provider.

With AllDayDesk, the setup starts by choosing your business or entering its website, checking the details it pulled, and hearing a personalized sample before you connect anything. The sample is a preview only — it does not create a real booking.

Once live, the setup answers using your saved business information. When it knows an answer, a price, or an open appointment slot, it shares it or books the appointment. When it does not know, it takes a message instead of guessing. New appointments go on the built-in AllDayDesk dashboard calendar by default, once you have configured your services and availability. If you prefer Google Calendar, you can optionally connect and authorize your Google account in Settings; no other external calendars or industry scheduling software are supported connections.

If you want certain calls handed to you directly, you configure a transfer destination and the rules for when transfers happen. A transfer is an attempt, not a guaranteed pickup — there is no promise that you answer or respond immediately.

Everything lands in your dashboard afterward: the calls, transcripts, summaries, and any bookings, so you can follow up on messages the same way you would with a note from a receptionist.

• Setup: choose your business or enter its website, verify details, hear a sample, then pick phone setup.
• Known answers, prices, and open slots are shared; unknown items become messages.
• Bookings default to the AllDayDesk dashboard calendar; Google Calendar is an optional connection in Settings.
• Changes to existing appointments are requests for you to approve, not confirmed changes.

There are three broad ways to handle inbound calls, and the right one depends on your call volume, budget, and how you work.

Doing it yourself costs nothing extra and gives the best customer experience when you are available, but it fails exactly when you are busy or closed. Voicemail is cheap and always available, but many callers will not leave a message or will call a competitor instead, and you cannot answer questions or book anything. An answering service fills the gap: human services employ people to answer, while AI services like AllDayDesk answer automatically using your business details.

Human services vary widely in price and coverage. For example, Ruby advertises live virtual receptionist plans starting at $245 per month, and Smith.ai uses per-call pricing for its human receptionist service — but a starting price alone tells you little; you have to compare included minutes or calls, overage rates, hours, and contract terms on a current quote. In-house reception covers much more than phones — greeting visitors and office tasks — so a phone service is not a full employee replacement.

This comparison describes documented features and published prices rather than hands-on testing, and AllDayDesk is this site's own product. Its plans include a set amount of minutes per month with per-minute overage rates, and pricing is displayed separately from this guide.

• Yourself: free, best when available, no coverage when busy or closed.
• Voicemail: always available, but callers often hang up and questions go unanswered.
• Human answering service: people answer; pricing and hours vary by provider and plan.
• AI answering service: automatic around-the-clock availability using your saved business details.

Start by looking at when your calls actually come in and when you cannot answer. If you miss calls mainly during work hours because you are on a job or with a customer, conditional forwarding (busy and no-answer only) may fit. If you want coverage nights and weekends too, forward all calls to the service and answer personally whenever you prefer.

Then check your provider's forwarding support for your exact plan, activate it, and test with a call from another phone. With AllDayDesk, setup means choosing your business or entering its website, reviewing the details it found, hearing a personalized sample, and then choosing your phone setup method. Configure your services and availability so the calendar can book real appointments, and decide whether you want transfers and to where.

A few practical tips: keep your saved business details current so answers stay accurate, review your dashboard transcripts regularly to catch questions the setup could not answer, and remember that messages — not confirmed changes — are what you get when a caller wants to move an existing appointment.

• Map your missed-call patterns to decide between conditional and all-call forwarding.
• Verify forwarding support with your exact carrier product before activating.
• Configure services and availability before expecting bookings on the calendar.
• Review transcripts and summaries in the dashboard to keep answers accurate.
