How to Forward My Office Phone to My Cell Phone

The single biggest mistake people make with forwarding is using a code that belongs to a different product. A code that works on a Verizon cell phone will not work on a Verizon business landline, and instructions for one Comcast product may not match another. Look at your monthly bill or your provider's welcome email and write down the exact service name.

You are looking for one of three setups. First, a traditional landline or digital voice line from a phone or cable company, which usually uses star codes dialed from the office phone itself. Second, a hosted or cloud business phone system, which usually manages forwarding in a web portal or app. Third, a cell phone used as your business line, which uses the carrier's wireless codes. Once you know which one you have, use only the instructions for that product.

• Check your bill for the exact product name, such as Business Voice, Digital Voice, or a hosted phone system.
• Note whether your office phone is a physical desk phone, a softphone app, or a cell phone.
• Confirm you can dial out from the office line, since most star-code activation must happen from that line.
• Ask your provider whether forwarding carries any per-minute or long-distance charges on your plan.

If you have a traditional or digital voice line, forwarding is usually a two-step dial: the code, then your cell number. Dial from the office phone itself, listen for the confirmation tone or message, and hang up. To turn forwarding off, dial the disable code from the same line. The table below covers providers with published instructions; always confirm against your own provider's guide, because codes can differ even within one company's product lineup.

• Verizon business landline: dial *72 and follow the activation instructions; dial *73 from the same line to turn it off.
• AT&T Phone for Business: dial *72, your destination, then # for all calls; *73# turns it off. No-answer forwarding is *92, destination, # and *93# turns it off; busy forwarding is *90, destination, # and *91# turns it off.
• AT&T Collaborate: *72 plus destination enables always forwarding and *73 disables it; *62 plus destination enables busy forwarding with *63 to disable; *92 plus destination enables no-answer forwarding with *93 to disable. Administrators control feature access.
• Comcast Managed Voice (Panasonic TPA65): lift the handset, dial *72 and the destination, then hang up; *73 disables. No-answer is *92 plus destination (*93 off) and busy is *90 plus destination (*91 off).
• Optimum Business Phone: dial *72, wait for dial tone, then dial the destination; a pickup confirms it. *73 turns forwarding 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.
• C Spire: dial *72 and the 10-digit destination, then press Call; *73 then Call disables it. C Spire has not published conditional codes, so confirm any no-answer option with them directly.
• Spectrum Business Voice: sign in to SpectrumBusiness.net, open Voice, choose your number, then Voice Settings or Forwarding Manager, enable forwarding, pick all calls or busy/no-answer, and set the destination.

Cloud business phone systems usually skip star codes entirely. In Vonage Business Communications, for example, you select Call Forwarding and enable forwarding to a phone number. Comcast Business Voice Mobility customers manage forwarding through My Account or the Comcast Business App, and Windstream OfficeSuite UC users set immediate forwarding in the WE Connect Dashboard under My Call Forwarding.

After you save the setting in any portal, test it by calling your office number from an outside phone, such as a friend's cell. Vonage specifically recommends verifying the destination with an outside call, and that advice is good practice everywhere. Remember that features depend on what your company subscribes to, so if the option is missing, ask your account administrator.

• Vonage Business Communications: select Call Forwarding and enable forwarding to your cell number.
• Comcast Voice Mobility: manage forwarding in My Account or the Comcast Business App.
• Windstream OfficeSuite UC: use the WE Connect Dashboard, My Call Forwarding widget, choose Immediate, Another Phone, enter the 10-digit number, and save.
• Test with a call from a different phone, not from the office line itself.

Some owners run their business on a cell line and want unanswered calls to reach another phone. On Verizon mobile, *72 plus the 10-digit destination forwards all calls, *71 plus the destination covers unanswered calls, and *73 disables forwarding. Setup must be done from the mobile phone while in Verizon coverage, and it forwards calls only, not texts.

T-Mobile uses GSM-style codes: **21*1 followed by the 10-digit number and # forwards all calls, **61*1 covers no-reply, **62*1 covers unreachable, and **67*1 covers busy. Add # to disable each one, for example ##21#, or use ##004# to reset forwarding to defaults. Check that your service and device support these codes. Charges depend on your plan, and forwarded calls may use plan minutes.

• Verizon mobile: *72 plus destination for all calls, *71 plus destination for unanswered, *73 to disable.
• T-Mobile: **21*1DESTINATION# all calls, **61*1 no reply, **62*1 unreachable, **67*1 busy; ## codes disable each, ##004# resets.
• Forwarding applies to calls, not text messages.
• Do not mix wireless codes with landline instructions for the same provider.

Forwarding comes in two main flavors. Unconditional forwarding sends every incoming call straight to your cell, and the office phone does not ring at all. Conditional forwarding only kicks in when the call is busy, unanswered after a set number of rings, or the line is unreachable. Many providers label these options as no-answer or busy forwarding, and hosted systems often let you pick a ring count before the redirect.

Choose unconditional forwarding when you are out of the office for the day and want nothing missed at the desk. Choose conditional forwarding when you want the desk phone to ring first during business hours and your cell to catch anything you do not pick up. One caution from provider guides: all-call forwarding overrides voicemail on the original line, so if you rely on your desk voicemail, conditional forwarding may fit better.

• Unconditional (all calls): every call goes to your cell immediately; the desk phone stays silent.
• No-answer: the desk phone rings first, then unanswered calls move to your cell.
• Busy: calls redirect only while you are already on another call.
• All-call forwarding usually overrides voicemail on the office line.

When a code fails or calls still ring at the desk, work through the basics before calling support. Confirm you dialed from the correct line, since most star codes only work from the phone being forwarded. Confirm the product name on your bill matches the instructions you used. Confirm your cell number includes the area code. And confirm the feature is actually included in your plan, because some carriers offer forwarding only in select areas or on certain plans, and administrators may need to enable it first.

If your provider publishes a portal or app for phone features, that is often the more reliable path than codes. When nothing works, a short call to your provider's business support with your account number and product name will settle which forwarding options your line supports.

• Dial activation codes from the office line itself, not your cell.
• Match the instructions to the exact product name on your bill.
• Include the area code in the destination number.
• Check plan eligibility and administrator permissions for the feature.
• Try the provider's web portal or app as an alternative to star codes.

Forwarding moves the call to your cell, but it does not answer the call for you. If you are on a job, driving, or with a customer, the caller still lands in your cell's voicemail, and callers who needed a quick answer may simply try the next business. That is the gap a 24/7 answering service fills: instead of forwarding to your cell, you forward the office line to a service that answers with your business information, takes messages, and can book appointments.

AllDayDesk is an AI receptionist that answers calls around the clock using the business details you save. You keep your existing number by forwarding calls to it, using the same provider steps above. Setup starts by choosing your business or entering its website, checking the details it found, hearing a personalized sample call, and choosing your phone setup. The sample is a preview only and creates no real booking. Once you have configured your services and availability, new appointments go on the built-in AllDayDesk calendar, and you can optionally connect Google Calendar in Settings after authorizing your account. Every call, transcript, summary, and booking shows up in your dashboard, and changes to existing appointments come to you as requests rather than confirmed edits. If a caller asks something AllDayDesk does not know, like a price you have not saved, it takes a message instead of guessing. You can also configure call transfers to your cell with your own rules, though pickup is not guaranteed.

• Forwarding to your cell still leaves missed calls in your cell voicemail.
• An answering service answers in your business name, takes messages, and can book appointments.
• AllDayDesk keeps your current number; you forward calls to it with your provider's steps.
• Calls, transcripts, summaries, and bookings appear in the AllDayDesk dashboard.
