How to Transfer Office Line to Cell Phone

Call forwarding sends incoming calls from your business number to another number you choose, in this case your cell phone. Callers dial the same office number they always have; the phone company simply routes the call to your mobile. Your callers notice nothing different.

There are two main types. All-call (unconditional) forwarding sends every incoming call straight to your cell, and your desk phone does not ring. Conditional forwarding only redirects calls under certain conditions, such as when the office line is busy or goes unanswered after several rings. All-call forwarding is the simplest choice when you want your cell to handle everything; conditional forwarding is useful when you still answer at the office most of the time.

Forwarding moves calls, not text messages. If customers text your office line, those messages stay where they were. Also check your plan, since some providers charge for forwarded minutes or count them differently.

• All-call forwarding: every call goes to your cell; the desk phone does not ring.
• Conditional forwarding: calls forward only when busy, unanswered, or unreachable.
• Texts are not forwarded, only calls.
• Some plans bill forwarded calls differently, so check with your provider.

This is the step people skip, and it is why forwarding instructions fail. The same carrier often sells several products with different codes. Verizon business landlines use *72, but Verizon wireless uses *72 for all calls and *71 for unanswered calls. AT&T Phone for Business, AT&T Collaborate, and AT&T wireless each have their own codes. Comcast Business has multiple voice products, and features depend on which one you subscribe to.

Look at your monthly bill or your account portal and write down the exact product name, such as Spectrum Business Voice, Frontier Digital Voice, Vonage Business Communications, or Comcast VoiceEdge. Then use the instructions for that specific product.

• Check your bill or portal for the exact service name.
• Do not mix codes between a carrier's landline, wireless, and hosted products.
• If the product name is unclear, call your provider's support line and ask which forwarding method applies to your line.

If your provider uses star codes, activation usually follows the same pattern: pick up the line, dial the code, enter your 10-digit cell number, and wait for confirmation. Confirmation is often a series of beeps, a stutter dial tone, or the forwarding system placing a call to your cell that you must answer. Here are verified examples for specific products:

Verizon business landline: dial *72 and follow the activation instructions; dial *73 from the same line to turn it off. Verizon wireless: dial *72 plus the 10-digit destination to forward all calls, *71 plus the destination for unanswered calls, and *73 to disable; setup must be done from the mobile while in Verizon coverage.

AT&T Phone for Business: dial *72, destination, then # for all calls; *92, destination, # for no-answer; *90, destination, # for busy. Disable with *73#, *93#, and *91# respectively. AT&T Collaborate uses *72 plus destination for always-forward, *62 for busy, and *92 for no-answer, with *73, *63, and *93 to disable.

Comcast Managed Voice (Panasonic TPA65): lift the handset, dial *72 and the destination, then hang up; *73 disables. Optimum Business Phone: dial *72, wait for dial tone, dial the destination, and have someone answer to 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. C Spire wireless: dial *72 plus the 10-digit number and press Call; *73 then Call disables. T-Mobile uses a different format: dial **21*1 followed by the 10-digit destination and # to forward all calls, and ##21# to disable, with conditional versions **61 (no reply), **62 (unreachable), and **67 (busy).

• Always wait for the confirmation tone, message, or callback before hanging up.
• Test with a real call from another phone after activating.
• Deactivate with the matching off code, usually *73, when you want calls at the office again.
• If a code gives an error, your line or product may not support it; contact your provider instead of trying another carrier's codes.

Many hosted and VoIP systems manage forwarding in an online dashboard rather than with star codes. Spectrum Business Voice, for example, has you sign in to SpectrumBusiness.net with an account role that can manage voice, open Voice, choose your phone number, then Voice Settings or Forwarding Manager, enable forwarding, pick all calls or busy/no-answer, and set the destination.

Vonage Business Communications lets you select Call Forwarding and enable forwarding calls to a phone number. Comcast Business manages phone features through My Account and the Comcast Business App, and available features depend on your subscribed services. Windstream OfficeSuite UC users set immediate forwarding in the WE Connect dashboard under My Call Forwarding, and can also route unanswered calls to another number after a chosen ring count.

After changing anything in a portal, verify the destination with an outside test call, because screens and saved settings vary between devices and accounts.

• Sign in with an account that has permission to change voice settings.
• Choose the forwarding type (all calls vs. busy/no-answer) and enter your cell number with area code.
• Save, then confirm with a test call from a different phone.
• Turn forwarding off in the same portal when you no longer need it.

Forward all calls when you will not be at the desk at all, such as when the office is closed or you are out on jobs all day. The desk phone stays silent and your cell handles everything.

Forward on no-answer or busy when you usually answer at the office but want a safety net. Calls ring the desk first, and only unanswered or busy calls follow you to your cell. Set the ring count long enough that you can realistically reach the desk. Note that on some systems, all-call forwarding overrides voicemail and hunt groups, so check how your line behaves before relying on it.

• All calls: best for full coverage away from the desk.
• No-answer/busy: best when the desk still answers most calls.
• All-call forwarding can override voicemail and hunt-group behavior on some systems.
• Confirm each mode with a test call, including a call you let ring out.

Forwarding to your cell means every work call interrupts your personal phone, around the clock if you leave it on. You also answer with your cell's greeting, not a business greeting, and if you are on another call, driving, or out of coverage, callers may reach your personal voicemail or get no answer at all.

A common next step is routing the office line to an answering service instead of, or in addition to, your cell. With AllDayDesk, you keep your existing business number and forward calls to the service; setup involves choosing your business or entering its website, checking the details it saved, hearing a personalized sample, and then choosing your phone setup method based on your provider's forwarding instructions. Calls, transcripts, summaries, and bookings show up in your dashboard. New appointments go to the built-in AllDayDesk calendar by default once you have configured your services and availability, and an optional Google Calendar connection is available in Settings after you connect and authorize your account. When the service does not know an answer, price, or opening, it takes a message for you. If you configure call transfers with a destination and rules, calls can be passed to you, though pickup is not guaranteed.

If your office number is a Google Voice number, note that Google explicitly does not support forwarding Google Voice calls to an automated system, so that path will not work for this kind of service.

• Forwarding to a cell puts work calls on your personal phone with no screening.
• An answering service can take messages and book appointments while you work.
• Existing appointment changes made by a service are requests for you to confirm, not automatic changes.
• Google Voice numbers cannot be forwarded to automated answering systems.

Most forwarding problems come down to one of three causes. First, the wrong instructions for your product, which is why identifying the exact service name matters. Second, the feature is not enabled on your account; some carriers require you to add forwarding as a feature before the codes work. Third, conditional forwarding is not supported on your line or device, which some carriers limit to select plans or handsets.

If a star code returns an error or a test call still rings the desk, call your provider and ask two questions: does my line support the forwarding type I want, and what is the correct activation method for my exact product? Do not substitute another carrier's codes, and do not assume a wireless code works on a business landline or the reverse.

• Reconfirm the exact product name on your bill.
• Ask your provider whether the feature is enabled on your account.
• Confirm conditional forwarding support for your specific line before relying on busy or no-answer modes.
• Test both activation and deactivation so you are never stuck with forwarding on.
