How to forward calls to a different number is one of those small skills that saves you from a lot of missed opportunities. You’re stepping out for lunch, heading to a client site, or working from the kitchen table, and the phone that matters is sitting on a desk somewhere else. Maybe you’re in the car when it rings, or in a meeting you can’t leave, or just trying to eat a sandwich in peace. Either way, a call comes in, nobody answers, and the caller moves on to the next business on their list.
Missed calls mean missed sales, or at the very least a few annoyed people who now think you’re hard to reach. The fix is simple, and it doesn’t need fancy equipment or a tech background. Once you set it up, your calls follow you wherever you go. They ring on the phone you actually have in your hand, so you stay reachable without staying glued to one desk all day.

It’s a phone feature that sends incoming calls to another number. Someone dials your number, your phone or phone system passes the call along, and the person on the other end picks up like normal. Most of the time, the caller has no idea the call was redirected.
People use it in all kinds of ways. You might forward phone calls to your mobile when you’re away from your desk, to a coworker while you’re on holiday, or to a landline when your cell has no signal. Businesses use it to route calls to the right team or to a backup line after hours. Knowing how to forward calls to a different number is one of the quickest ways to stay reachable without being stuck next to one phone.
There are two main kinds. Unconditional forwarding sends every call away, all the time. Conditional forwarding only kicks in under certain conditions, such as when you’re busy or don’t answer. We’ll cover both below.
A good way to picture it is mail forwarding for your phone. You don’t change your address, and the post still finds you. Your number stays exactly the same, which is the whole point, because nobody has to update a contact card or learn something new.
The exact buttons depend on your phone and your provider, but the steps are almost always the same. Here are six:
Pick a number that will actually be answered, such as your mobile, a coworker’s line, or a backup number.
Check the forwarding section of your phone’s call settings, your provider’s app or online account, or look up a dial code on your provider’s website.
Write it out in full, include country code if calls are to be made outside of the country.
All calls or only calls received while busy, don’t answer or cannot be reached.
Check for a message or a small icon to indicate that it’s on.
Call your number from a different phone and make sure the right person picks up, then note how to turn it off so you don’t forget.
A quick warning about dial codes. They differ by country and by provider, so check your carrier’s help page before you type one in. A wrong code can switch on the wrong setting, and that’s a headache to untangle.
Also remember that forwarded calls may use up minutes or cost extra, especially when they go to a mobile or an international number. A quick look at your plan before you switch it on can save you from a surprise bill.
Dialinger is a cloud based call forwarding service that lets you forward calls coming into your virtual or business phone number to any other local, mobile or international number.

Sending every call away isn’t always what you want. Sometimes you only need a backup in case you can’t pick up. That’s where conditions come in. When you forward a phone call to another number only under certain conditions, you stay in control of your line and still avoid missed calls. It’s also a smarter answer to how to forward calls to a different number, because the setup fits the way you actually work.
Here are the conditions people use most:
Some carriers use dial codes for these rules, and many phone systems let you tick the options on a settings page. Not every plan offers every condition, so check what yours supports before you count on it.

VoIP call forwarding works over the internet, so you set it up from an app or a web dashboard instead of punching codes into a keypad. It’s usually much more flexible than the basic version on a traditional line. You can send calls to several numbers at once, set different rules for different hours, and change everything from your laptop in a few clicks. That’s why many teams choose it when they need to forward a phone call to another number quickly, without waiting on a provider to make the change.
It also makes life easier for teams. When you work out how to forward calls to a different number across a whole office, one admin can manage every rule from one place instead of each person fiddling with their own phone. Calls can ring on a mobile app, a laptop, and a desk phone at the same time, so nobody has to rely on a single device. For remote and hybrid teams, that’s a big deal, because people can answer from wherever they happen to be.
A good setup gives you more than just fewer missed calls. Here are six benefits you’ll notice:
Calls reach you even when you're away from your desk, in a meeting, or out for the day.
Customers get a real person instead of a ringing line, and they're far more likely to stay patient.
You can forward phone calls to a mobile, a home office, or another city whenever your plans change, without telling every customer a new number.
You have one public number and calls are sent where they are needed, it looks neat and reliable.
It often costs less than adding extra lines, and VoIP call forwarding can save even more because you set it up online with no technician visit.
You can travel, take time off, or step out for an appointment without worrying about an important call going unanswered.
None of this needs a big budget. Most of it comes with the plan you already have, or for a small monthly fee, which makes it one of the easiest upgrades a small business can make.
Nothing is more annoying than setting everything up and then finding out the calls never arrive. The good news is that most problems have simple causes. Before you panic, go back over how to forward calls to a different number step by step, and check each part. Here are four fixes to try:
If none of that works, restart your phone and test from a different line. Still nothing? Contact your provider and tell them exactly what you tried. That saves everyone time.
A few habits make the feature work for you, and they’re worth remembering each time you set up how to forward calls to a different number:
If calls will land on someone else's phone, let that person know so they answer politely and know what to say.
Add a second number or a voicemail for when the first one doesn't answer, so no call hits a dead end.
Forgotten forwarding can send calls to the wrong place for days, so set a reminder on your calendar.
Run a quick test call after any phone or plan change, and always before a trip or holiday, when you most need to forward phone calls without a hitch.
One more thing to keep in mind is caller ID. Some systems show the original caller on the receiving phone, while others show your number instead, so check what your team will see before you rely on it.
If you’d like more control than a basic phone gives you, Dialinger is worth a look. It’s a cloud-based communication platform, so you can manage calls from a dashboard and from mobile and desktop apps. Its forwarding feature is a good place to start if you’re working out how to forward calls to a different number for yourself or a whole team, and it’s a simple way to forward a phone call to another number when you’re out. The virtual phone system page also explains how cloud calling fits together. Before you commit, ask how VoIP call forwarding rules work for your setup, such as busy, no-answer, and after-hours routing, and how quickly you can forward phone calls when plans change.
Usually not. They dial your number, hear it ring, and someone picks up. A few systems play a short message, and a long delay before the ring can give it away, but most callers never notice.
It depends on your provider and plan. Some include it for free, while others charge a small fee or use up your minutes, especially when calls go to a mobile or an international number. Check your plan before you switch it on so there are no surprises on your next bill.
Forwarding happens before you answer. The call is sent to another number automatically. Transferring happens during a call, when you answer first and then pass the caller to someone else. Forwarding keeps you from missing calls, and transferring helps you hand a caller to the right person.
On a basic phone line, usually just one at a time. Many VoIP and business phone systems go further. They can ring several numbers at once, or try them one after another until someone answers. That’s handy for teams that share a line.
