Telephone Answering Service Software: A Buyer's Guide

Answering service software sits between your callers and you. When a call comes in, the software answers using information you have saved about your business: your services, prices you want shared, hours, and location. It can answer common questions, take a message, and book new appointments. Everything it handles shows up in a dashboard where you can read call summaries and transcripts.

With AllDayDesk specifically, setup starts by choosing your business or entering its website so the system can pull in your details, checking that the information is right, and hearing a personalized sample of how your calls would be answered. The sample is a preview only and does not create a real booking. After that, you choose how to connect your phone. 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, an optional connection is available in Settings after you connect and authorize your Google account.

Two limits matter when you compare products. First, around-the-clock availability is not a promise that every single call connects, so read availability claims carefully. Second, when a caller asks something the software does not know, like a price it has not been given, it takes a message instead of guessing. Changes to existing appointments are passed to you as requests, not confirmed changes, so you stay in control of your schedule.

• Answers calls with your saved business details
• Takes messages when it does not know an answer
• Books new appointments on a dashboard calendar, with optional Google Calendar in Settings
• Shows calls, transcripts, summaries, and bookings in one dashboard
• Keeps your existing phone number through call forwarding

The other main option in this category is a live answering service staffed by people. Companies like Ruby, Smith.ai, and AnswerConnect provide human receptionists who answer on your behalf. Ruby advertises plans starting at $245 per month as of October 2026, and Smith.ai uses per-call pricing that depends on the needs you select. Those starting prices are not complete costs; you need a current quote to see included minutes or calls, overage charges, hours, and contract terms.

Software and human services are different tools, and the right choice depends on what you need. A human service can handle judgment calls and unusual requests in a way software cannot. Software is available around the clock and answers consistently from your saved information. Human coverage and fees vary by service and plan, so do not assume people always cost more or only work business hours. Note that some providers, such as Smith.ai, offer both an AI receptionist and human receptionists as separate services, so read product pages closely.

• Human services: judgment, flexible handling of odd requests, priced per quote
• Software: consistent answers from your saved info, around-the-clock availability, dashboard records
• Compare included minutes, overage rates, hours, and contract terms before deciding
• Some providers sell AI and human services separately under one brand

Before buying any answering service software, work through the questions below. They apply whether you choose AllDayDesk or another provider.

• Call volume: estimate how many minutes of calls you get monthly, since many plans include a set number of minutes and charge per extra minute
• Booking needs: decide whether you need appointment booking, and whether the product supports your calendar; AllDayDesk uses its own dashboard calendar by default with optional Google Calendar in Settings
• Phone compatibility: confirm how you will forward your existing number, and check your carrier's instructions before signing up
• Information accuracy: the software answers from what you save, so look for an easy way to review and correct your business details
• Visibility: make sure you can see calls, transcripts, summaries, and bookings yourself rather than relying on notifications alone
• Escalation: if you want calls transferred to you, check that the product lets you configure a destination and rules, and understand that pickup is not guaranteed
• Limits: ask what happens when the software does not know an answer; a good product takes a message instead of guessing

You can keep your existing business number and forward calls to the answering service, and the exact steps depend on your phone provider. AllDayDesk supports this by letting you keep your public number; the forwarding instructions come from your carrier, not from AllDayDesk.

A few verified examples show how much carriers differ. Verizon mobile uses *72 plus the 10-digit destination for all-call forwarding, *71 for unanswered calls, and *73 to turn it off, set from the phone itself while in coverage. T-Mobile uses **21*1, destination, # for unconditional forwarding and ##21# to disable. Comcast Business manages forwarding through its My Account portal or app, and features depend on which service you subscribe to, so identify your exact product first. Google Voice is a special case: Google explicitly says forwarding calls from a Google Voice number to an automated system is unsupported, so do not plan on that path.

Because codes and menus vary by product, look up your provider's own guide before you activate anything, and test with a real call from another phone after setup.

• Verizon mobile: *72 + destination to forward all calls, *71 for unanswered, *73 to disable
• T-Mobile: **21*1 + destination + # for all calls, ##21# to disable
• Comcast Business: managed in My Account or the app; features depend on your subscribed service
• Google Voice numbers cannot be forwarded to an automated system

Once your service is live, the work shifts to keeping your saved information current. Update your services, prices, and hours whenever they change, because the software answers from exactly what you saved. Check the dashboard regularly to read transcripts and summaries, confirm bookings, and handle appointment-change requests that were passed to you.

If you want some calls handed to you directly, configure your transfer destination and rules in advance, and remember that neither pickup nor an immediate response is guaranteed on a transfer. Finally, if you use Google Calendar, connect it in Settings after authorizing your account so bookings land where you already work.

• Keep services, prices, and hours up to date in your saved business info
• Review transcripts and summaries in the dashboard
• Treat appointment changes as requests you approve
• Set up transfer destinations and rules before you need them
