How to Divert Business Landline to Mobile

The single biggest mistake owners make is using star codes for the wrong product. A carrier often sells several phone services, and the activation steps for one will not work on another. For example, AT&T publishes different codes for AT&T Phone for Business than for AT&T Collaborate, and Comcast Business features depend on whether you have Voice Mobility, Business Voice, VoiceEdge, or Managed Voice.

Check your monthly bill or your provider's welcome paperwork for the exact service name. If you cannot find it, call your provider's business support line and ask which product your line is on and whether call forwarding to an outside number is included in your plan.

• Look for the product name on your bill, such as Business Voice, Digital Voice, or a hosted system.
• Ask your provider whether forwarding to an outside number is included or costs extra.
• Find out whether your system is managed by star codes from the handset or by an online portal or app.

If your service uses star codes, the most common pattern is *72 to turn forwarding on and *73 to turn it off. The exact sequence depends on your provider and product, so use only the directions published for your service.

Some services also support conditional diverting, which forwards only when the line is busy or unanswered, instead of sending every call. Not every product offers this, and the codes vary, so confirm with your provider before relying on it.

• AT&T Phone for Business: dial *72, the destination, then # to forward all calls; *73# turns it off. No answer uses *92 with the destination and #, off with *93#. Busy uses *90 with destination and #, off with *91#.
• AT&T Collaborate: *72 plus the destination enables always forwarding, *73 disables. Busy forwarding uses *62 with destination, off with *63. No-answer uses *92 with destination, off with *93. An administrator controls feature access.
• Verizon business landline: dial *72 and follow the activation instructions; dial *73 from the same line to deactivate.
• Optimum Business Phone: dial *72, wait for dial tone, then dial the destination. The destination answering confirms it. If busy or unanswered, press the flash or hook switch, dial *72 again, and redial the destination; two beeps and dial tone confirm. *73 turns it off.
• Frontier Unlimited Digital Voice: lift the handset, dial *72, wait for a second dial tone, enter the destination, and listen for confirmation. *73 disables it.
• Comcast Managed Voice (Panasonic TPA65 guide): lift the handset, dial *72 and the destination, then replace the handset. *73 disables. No-answer is *92 plus destination, off with *93; busy is *90 plus destination when call waiting is off, disabled with *91.
• C Spire: dial *72 and the 10-digit destination, then press Call. Disable with *73 then Call.

Cloud and hosted business phone systems usually handle diverting in a web dashboard or mobile app rather than with star codes. You sign in, select your phone number or extension, and set a forwarding destination.

Spectrum Business Voice, for example, manages forwarding through SpectrumBusiness.net: sign in with a role allowed to manage voice, open Voice, choose the phone number, then use Voice Settings or the Forwarding Manager to enable forwarding, pick all calls or busy/no-answer, and set the destination. Vonage Business Communications lets you select Call Forwarding and enable forwarding to a phone number. Windstream OfficeSuite UC uses the WE Connect dashboard's My Call Forwarding widget, where you can set immediate forwarding to another phone number and choose a ring count before unanswered calls divert.

Comcast Business customers can manage phone features, including remote call forwarding, through My Account and the Comcast Business App, depending on the services they subscribe to.

• Sign in to your provider's business portal or app with an account that has permission to change phone settings.
• Select the specific phone number or extension, then find the forwarding or call settings area.
• Choose whether to divert all calls or only busy and unanswered calls, then enter your 10-digit mobile number.
• Save the change and test it with an outside call before you rely on it.

After activating a divert, call your business number from a phone other than your mobile and confirm the call rings on the mobile. Check the call quality and make sure the caller ID your customers see behaves the way you expect.

Keep the deactivation code handy. In nearly every star-code service, dialing *73 from the same line turns the divert off. In portal-based systems, return to the same forwarding screen and disable it there. Remember that forwarding all calls means your desk phone will not ring at all while the divert is active, and on some services forwarding overrides the line's voicemail.

A few practical cautions: forwarding applies to calls, not text messages. Some mobile carriers require setup from the mobile phone itself while in coverage, and charges depend on your plan, so ask your provider how diverted calls are billed.

• Test with an outside call before trusting the divert.
• Write down the deactivation code or portal path so you can turn it off quickly.
• Ask your provider whether diverted calls use plan minutes or carry per-minute charges.

Diverting to a mobile works well when you can answer, but it has limits. Every call rings your personal phone, including spam and after-hours callers, and if you are on another call, in a meeting, or out of range, the caller may reach your mobile voicemail or nothing at all.

An answering service takes a different approach: calls are answered on your behalf, messages and details are captured, and you review them later. AllDayDesk is this site's own AI receptionist that answers calls around the clock using your saved business information. You keep your existing business number by forwarding calls to it, using the same carrier steps described above. Setup involves choosing your business or entering its website, checking the details it found, hearing a personalized sample, and choosing how to connect your phone. Calls, transcripts, summaries, and bookings show up in your dashboard, and new appointments go to the built-in calendar once you have set your services and availability, with an optional Google Calendar connection available in Settings after you connect and authorize your account. When the answer, price, or appointment is unknown, it takes a message for you, and if you configure call transfers with a destination and rules, it can transfer callers who need you directly.

If you are weighing options, compare what each approach actually does rather than assuming one is universally cheaper or better. Human virtual receptionist services exist alongside AI options, and their pricing, hours, and included allowances vary, so request current quotes before deciding.

• Mobile diverting sends every call to your personal phone, including ones you cannot take.
• An answering service answers on your behalf and collects messages and booking details you review later.
• AllDayDesk uses your existing number through forwarding, so customers keep calling the same line.
