Best Call Forwarding Service for Business

Call forwarding sends incoming calls from your business number to a different destination. Unconditional (all-call) forwarding sends every call immediately. Conditional forwarding only kicks in when the line is busy, nobody answers, or the phone is unreachable. Many businesses use conditional forwarding so they keep answering their own phone during the day and only hand off calls they miss.

Forwarding itself does not answer anything. It just reroutes the call. What happens next depends on the destination: your cell phone, a coworker, a voicemail box, or an answering service. That destination choice is usually the real decision, not the forwarding feature.

• Unconditional forwarding: every call goes to the destination right away.
• Conditional forwarding: calls only forward on busy, no answer, or unreachable.
• Forwarding keeps your published business number, so customers dial the same number as always.
• Some carriers charge for forwarded minutes depending on your plan, so check before you activate.

Business forwarding options fall into three groups. Knowing which group your phone service belongs to is the first step, because the setup steps and features differ a lot between them.

Carrier built-in forwarding is included with many phone plans. Verizon mobile uses *72 plus the destination to forward all calls and *71 for unanswered calls, with *73 to turn it off; setup must be done from the phone while in Verizon coverage. AT&T Phone for Business uses *72 for all calls, *92 for no answer, and *90 for busy, each followed by the destination and #. Comcast Business offers call forwarding and remote call forwarding through Voice Mobility, with features managed in My Account and the Comcast Business App; the exact steps depend on which Comcast product you subscribe to. Vonage Business Communications lets you select Call Forwarding and forward calls to a phone number.

Hosted phone portals usually combine star codes with a web dashboard. Spectrum Business Voice is managed by signing in to SpectrumBusiness.net with an account role that can manage voice, opening Voice, choosing the phone number, and setting forwarding in Voice Settings or the Forwarding Manager, where you can pick all calls or busy/no-answer. Optimum Business Phone uses *72 then the destination, with *73 to disable, and also manages forwarding in My Optimum Voice. Windstream OfficeSuite UC handles immediate forwarding through the WE Connect dashboard widget and lets you set ring counts before unanswered calls forward.

Answering services and virtual receptionists are the destination, not just the pipe. Human services like Ruby (plans advertised from $245 per month as of October 2026) and Smith.ai (per-call pricing) answer forwarded calls with people. AI receptionists like AllDayDesk answer with software trained on your business information. The forwarding step is the same; what changes is who or what picks up.

• Carrier built-in: cheapest to start, but features are limited to what your plan includes.
• Hosted portal: more control (ring counts, busy/no-answer rules), managed through a web login.
• Human answering service: real people answer; pricing is usually per minute or per call.
• AI receptionist: software answers, takes messages, and can book appointments; usually flat monthly pricing.

Before activating anything, work through these questions. They will point you to the right category and save you from forwarding calls to something that cannot handle them.

• What phone service do I actually have? Check your bill or provider portal for the exact product name. AT&T Collaborate codes differ from AT&T Phone for Business codes, and Comcast Managed Voice steps differ from other Comcast Business products. Using the wrong product's instructions is the most common setup failure.
• Do I want all calls forwarded or only missed ones? If you answer your own phone during business hours, conditional (busy/no-answer) forwarding is usually the better fit. Note that not every plan supports every conditional option; some carriers only verify all-call forwarding.
• Where should calls land? A cell phone works for one person. If you need calls answered, messages taken, or appointments booked while you are unavailable, you need a destination that can actually do those things.
• What does forwarding cost on my plan? Some carriers bill forwarded calls as outgoing long distance. Ask your carrier before relying on it.
• How will I test it? Always verify by placing a real outside call to your business number after activating. Optimum's own guide recommends confirming the destination answers; the same test applies everywhere.

Carrier support is not uniform, and this is where many setups go wrong. Verizon mobile supports all-call forwarding (*72) and no-answer forwarding (*71), but the setup must happen from the phone itself. C Spire publishes all-call *72 forwarding but does not publish verified conditional codes, so you would need to confirm no-answer or busy forwarding with C Spire directly rather than borrowing another carrier's codes. Tracfone forwarding is only available in select areas and on select handsets. Cricket lists call forwarding as a standard feature but directs you to your specific device guide for setup.

One important limit: Google Voice can forward calls to linked phone numbers, but Google explicitly states that forwarding calls from a Google Voice number to an automated system is unsupported. If your business runs on Google Voice, forwarding to an AI receptionist is not a supported path, and you should confirm alternatives with your provider instead of assuming it will work.

The safest sequence is: identify your exact product from the bill, find that product's own instructions, activate, then place a real test call from a different phone. If a conditional option fails to activate, contact your carrier to confirm whether that feature is available on your specific plan.

• Identify the exact product name before using any star code or portal path.
• Never borrow conditional codes from a different carrier; they may not exist on your plan.
• Google Voice numbers cannot be forwarded to automated answering systems.
• Test with a real outside call after every activation or change.

If the point of forwarding is to have someone or something answer when you cannot, the destination matters more than the forwarding feature itself. Human answering services like AnswerConnect staff phones with people around the clock, with pricing based on usage. AI receptionists answer with software: AllDayDesk, for example, answers calls using business information you save, takes messages, and can book appointments into a built-in calendar once you have configured your services and availability.

With AllDayDesk you keep your existing number and forward calls to it using whatever method your phone service supports. Setup involves choosing your business or entering its website, checking the details it found, hearing a personalized sample call, and then choosing your phone setup. Calls, transcripts, summaries, and bookings show up in your dashboard afterward. If a caller asks something the service does not know, like a price it has not been given, it takes a message instead of guessing.

One thing to plan for: transfers to you require you to configure a destination and rules ahead of time, and a transfer is not guaranteed to connect. Also note that changes to existing appointments come to you as requests to approve, not confirmed changes.

• Human answering services answer with people; pricing is usually usage-based.
• AI receptionists answer with software using your saved business details.
• AllDayDesk keeps your existing number; you forward calls to it with your carrier's own method.
• Transfers to you must be configured in advance and are not guaranteed to connect.
• Appointment changes arrive as requests for you to approve, not automatic changes.

These are the failures that come up most often when businesses set up forwarding, and each one is easy to prevent with a quick check.

• Using a wireless code on a landline product or vice versa. Verizon mobile *71 has no equivalent in the Verizon business landline guide, which only covers *72 all-call forwarding.
• Forgetting that all-call forwarding overrides voicemail. Frontier's Digital Voice guide notes that all-call forwarding prevents calls from reaching the original line entirely, including its voicemail.
• Leaving forwarding on after a test. Dial *73 (or your product's disable code) when you are done testing so calls return to normal.
• Assuming texts forward. Verizon mobile forwarding covers calls only, not text messages.
• Forwarding to a number that cannot answer, such as an unstaffed second line, and finding out from a missed customer.
