Call Forwarding From Office Phone to Cell Phone

When forwarding is active, your office number keeps working exactly as before. Callers dial the same business number they always have; the phone network simply rerings your cell instead of the desk phone. That means you can leave the office without asking customers to learn a new number.

There are two main kinds of forwarding. Unconditional (sometimes called all-call or immediate) forwarding sends every incoming call straight to your cell. Conditional forwarding only kicks in when the desk line is busy or nobody picks up after a set number of rings, so the desk phone still works normally when you are there.

One trade-off to know: with all-call forwarding active, the desk phone generally will not ring at all, and forwarding can override the line's voicemail. If you want the desk phone to keep working during the day, conditional forwarding is usually the better fit.

• Unconditional forwarding: every call goes to the cell; the desk phone does not ring.
• Conditional forwarding: calls only move to the cell when the desk line is busy or unanswered.
• Your business number stays the same; callers see no difference.
• Forwarding applies to calls, not text messages.

The activation code depends on which product you actually have, and the same brand often sells several different phone services with different steps. Check your bill or account page for the exact product name first, then use the matching instructions below.

• Verizon business landline: dial *72 and follow the activation instructions from the office line; dial *73 to deactivate.
• AT&T Phone for Business: all calls *72, destination, # (off *73#); no-answer *92, destination, # (off *93#); busy *90 (off *91#). AT&T Collaborate differs: always *72 (off *73), busy *62 (off *63), no-answer *92 (off *93), with administrator-controlled feature access.
• Comcast Managed Voice (Panasonic TPA65): lift the handset, dial *72 and the destination, then hang up; *73 disables. No-answer is *92 (off *93) and busy is *90 (off *91). Other Comcast Business products are managed through My Account or the Comcast Business App instead.
• Spectrum Business Voice: sign in to SpectrumBusiness.net, open Voice, choose your number, then Voice Settings or Forwarding Manager, enable forwarding, choose all calls or busy/no-answer, and set the destination.
• Optimum Business Phone: dial *72, wait for dial tone, then dial the destination; the destination answering confirms it. *73 turns forwarding off.
• Frontier Unlimited Digital Voice: lift the handset, dial *72, wait for the second dial tone, enter the destination, and listen for confirmation; *73 disables. Some Frontier Digital Voice services also offer Find Me/Follow Me or Simultaneous Ring.
• Vonage Business Communications: select Call Forwarding and enable Forward Calls to a phone number, then verify with an outside call.
• Windstream OfficeSuite UC: in the WE Connect Dashboard, open My Call Forwarding, choose Call Forwarding (Immediate) and Another Phone, enter the 10-digit number, and save; choose None to disable.

Whichever provider you use, the process follows the same shape: identify your exact service, dial the activation code or set the portal option, then prove it works before you rely on it.

A practical checklist for the first setup:

• Find the exact product name on your bill or account page; brand names alone are not enough, since one company may sell several phone products with different steps.
• Dial the activation code from the office line itself, or use the provider's web portal if your product is managed there.
• Place a test call to your office number from a different phone and confirm it rings your cell.
• Test the busy and no-answer cases too if you set conditional forwarding, for example by calling while the desk line is in use.
• Write down the deactivate code (often *73) so you can switch back quickly.
• Remember that charges can depend on your plan, especially if forwarding routes calls in a way your plan treats as long distance.

Forwarding moves the call, but it does not move everything else. While all-call forwarding is on, the desk phone stays silent and the line's voicemail may never pick up, since the forwarding takes priority. If your cell battery dies or you are on another call, a caller may reach your cell's voicemail instead of your business greeting.

Conditional forwarding is not supported on every line or plan. Some wireless carriers and budget plans only offer all-call forwarding, and a few device guides note forwarding is available only in select areas. If a conditional code fails, call your provider and ask whether busy/no-answer forwarding is supported on your specific line rather than trying another carrier's codes.

A special note for Google Voice: Google explicitly does not support forwarding calls from a Google Voice number to an automated answering system. If your business number is a Google Voice number, forwarding it to an automated receptionist is not a supported path.

• All-call forwarding overrides the desk phone's voicemail.
• Missed calls may land in your cell's voicemail, not your business greeting.
• Conditional forwarding may not be available on every plan or device; confirm with your provider.
• Google Voice numbers cannot be forwarded to automated systems.

Forwarding to your own cell works well when you are the one who should answer. It works less well when you are on a job, with a customer, or asleep, because every call still interrupts you and unanswered calls fall to your personal voicemail.

An answering service sits in the middle: you forward the same office line, but a service answers instead of your cell. AllDayDesk, this site's own product, is an AI receptionist that answers calls around the clock using your saved business information. You keep your existing number by forwarding it, hear a personalized sample before anything goes live, and can review calls, transcripts, summaries, and bookings in the dashboard. When it does not know an answer or a price, it takes a message instead of guessing, and appointment changes on existing bookings are passed to you as requests rather than confirmed changes.

Human answering services are another option. Published starting prices vary by provider, for example Ruby advertises plans starting at $245 per month, while Smith.ai uses per-call pricing for its human receptionist service, so compare included minutes or calls, overage rates, hours, and contract terms on a current quote rather than the headline number.

• Forwarding to your cell: free or low cost, but every call interrupts you.
• AI receptionist like AllDayDesk: answers around the clock, takes messages, books appointments you configure.
• Human answering services: real people, with pricing that varies by plan and usage.
• In-house receptionists handle visitors and office tasks beyond the phone, so compare scope, not just cost.
