Staring at a missed call notification feels like watching a customer walk right out the door. It’s a modern business frustration, but a solvable one. Learning how to use call forwarding is your best bet for making sure you catch every single opportunity by automatically sending calls from one number to another. It’s the simplest way to turn your phone into your most reliable employee.
Never Miss a Business Call Again
For any service business, a missed call is a missed opportunity. Think about a mobile locksmith rushing to a lockout or a busy medical clinic juggling appointments—that single unanswered ring can mean lost revenue. Call forwarding isn't just a nifty phone feature; it's a fundamental tool for customer service and, frankly, for protecting your bottom line. It’s the safety net that ensures when a client reaches out, someone—or something—is always there to answer.
This isn't new tech, by the way. Long before you could just toggle it on in your smartphone settings, call forwarding was a quiet survival tool for small businesses. As mobile subscriptions exploded past 1 billion globally by 2002, it became one of the first network features carriers pushed to business users, letting them take office calls on the go. Today, the global call-forwarding market is on track to hit over $8 billion, mostly because it's so tightly woven into modern VoIP and cloud phone systems.
The Core Types of Call Forwarding
Getting a handle on the different forwarding options lets you build a system that actually works for you. Instead of a blunt, one-size-fits-all approach, you can create smart rules that adapt to your schedule and whether you're available or not.
Here’s a quick breakdown of the main types and what they’re good for.
Types of Call Forwarding at a Glance
| Forwarding Type | What It Does | Best For |
|---|---|---|
| Unconditional | Sends all incoming calls to another number, immediately. | Vacations, dedicated after-hours services, or when you need zero interruptions. |
| Conditional: Busy | Forwards calls only when you're already on another call. | Making sure you don't miss a new lead while closing a deal with a current client. |
| Conditional: No Answer | Forwards calls if you don't pick up after a set number of rings. | Solo operators who need to focus on a job but want a backup to catch calls they can't get to. |
| Conditional: Unreachable | Forwards calls if your phone is off, in airplane mode, or has no signal. | Traveling through areas with spotty service or ensuring business continuity if your device dies. |
These options give you the building blocks to design a call flow that fits your business like a glove.

Unconditional Forwarding: This one is as straightforward as it gets. It sends all incoming calls to whatever number you designate, and your primary phone won't even ring once. It's perfect for when you're on vacation and want everything to go to a team member, or if you're funneling all calls to a dedicated answering service.

Conditional Forwarding: This is where things get more interesting. Conditional forwarding gives you flexibility by letting you set specific rules. You can have calls forwarded only when your line is busy, when you don't answer after a few rings, or if your phone is unreachable because it's off or has no signal.
A solo contractor can set their phone to forward unanswered calls to an assistant after three rings. This simple setup lets them focus on the job at hand without the nagging worry of losing the next one. It transforms their phone from a constant distraction into an automated lead-capture machine.
When you pair these methods with a modern AI assistant like Marlie.ai, the strategy gets even smarter. A busy pharmacy, for example, could use conditional forwarding to send all after-hours calls to an AI that handles refill requests and answers common questions about store hours. This not only gives customers a better experience but also protects your team from burnout.
You can see how a 24/7 answering service can automate this whole process for you, turning missed calls into a thing of the past.
Configuring Call Forwarding on Any Device
Setting up call forwarding shouldn't be a headache. Whether you're on a job site with your iPhone or at your desk managing the company’s phone system, the whole point is to get your calls redirected in minutes, not hours.
Let's walk through how to actually get this done on the most common devices and platforms you're likely using.
The idea is simple: an incoming call that would otherwise be a missed opportunity gets captured through smart forwarding.
This isn't just about convenience; it's a direct intervention to stop business from slipping through the cracks.
Setting Up on Smartphones
For most of us using a mobile phone, the setup is right there in your device's settings. The exact menu names might differ a little, but the basic path is the same.
For iPhone (iOS) Users:
Just head into Settings and tap on Phone. In that menu, you'll see Call Forwarding. Flip the switch on and punch in the phone number you want your calls sent to. That's it. Your iPhone will now send all incoming calls straight to that number.
For Android Users:
On your Android, open the Phone app, tap the three-dot menu icon, and go into Settings. From there, look for something called Calling accounts or Supplementary services. Inside, you'll find the Call Forwarding options where you can choose to forward calls when your line is busy, unanswered, or unreachable.
For a more granular breakdown, our guide on how to forward cell phone calls covers more specific models and scenarios.
Using Universal Carrier Codes
Sometimes the fastest way to get this done is by punching a code directly into your phone’s dialer. These "star codes" talk directly to your carrier’s network and are pretty much universal across major players like AT&T and Verizon.
- To Activate: Dial *72 immediately followed by the 10-digit phone number you want to forward to (like
*72-555-123-4567). Hit the call button, listen for the confirmation tone, and you're all set. - To Deactivate: Just dial *73 and press call. This instantly turns off all call forwarding on your line.
These codes are a lifesaver for field technicians or anyone on the move who needs to redirect calls without digging through settings menus. It’s a two-second action that can save a valuable lead.
Configuring on Business VoIP Systems
If your business runs on a Voice over Internet Protocol (VoIP) system, you're playing a whole different ballgame. These platforms are built for this stuff and offer far more sophisticated routing rules than a standard smartphone ever could.
Most VoIP providers give you an easy-to-use online dashboard. Once you log in, you'll find a section labeled "Call Handling," "Routing," or "Users." This is where the magic happens. You can create advanced rules, like forwarding calls based on the time of day, routing specific callers to different numbers, or even setting up a sequence where a call rings multiple people before it finally goes to voicemail or an assistant.
Think about a dental office, for instance. They could set their VoIP system to automatically forward any call after 5 PM to an on-call number or an AI receptionist. This ensures no patient emergency ever gets missed. This level of granular control is exactly what makes business phone systems so powerful.
Putting Your Call Forwarding to Work
Okay, you've got the basics down. Now, let's move beyond just setting up call forwarding and turn this simple phone feature into a real strategic asset—one that actually helps your bottom line.
This is where the magic happens. It’s about using forwarding not just to catch calls, but to build intelligent workflows that filter, prioritize, and capture revenue you might otherwise miss.
Picture this: an HVAC contractor is on a job, up on a roof. A new lead calls. Instead of that call ringing out or going to a generic voicemail, it’s automatically forwarded to an AI assistant. The AI can gather the caller's details, answer basic questions, and even get an appointment on the calendar. Just like that, a potential job that would have been lost is now secured.
This proactive approach is what separates thriving businesses from those just scraping by. It's about designing a system that works for you, especially when you can't pick up the phone yourself.
Create Intelligent Workflows with Conditional Forwarding
Conditional forwarding is your secret weapon for building a smarter communication system. It lets you create rules that automatically sort and direct calls based on who's calling or when, saving you from constant interruptions while ensuring the important calls still get through.
Here are a few practical ways to use it:
- The VIP Client Lane: You can set a rule to forward calls from your top clients directly to your personal cell, making sure they always reach you. Meanwhile, all other numbers can go straight to your AI assistant for screening.
- The After-Hours Assistant: A pharmacy can use time-based rules to forward all calls after 6 PM to a system that handles automated refill requests or provides store hours. No more missed calls from patients needing basic info.
- The Busy Line Backup: Let's say you're on a long call with a supplier. Any new incoming call can be automatically forwarded to a team member or an AI that can book the next job, so you don't have to cut your current conversation short.
This isn't just about answering more calls; it’s a smarter way to handle call routing that brings order to your inbound communication. To dig deeper into this, check out our guide on what is call routing and see how you can apply these principles more broadly.
The goal is to design a system that makes decisions for you. Your phone should know which calls need your immediate attention and which ones can be handled by an automated system, freeing you to focus on the high-value work right in front of you.
When you use it this way, call forwarding becomes directly tied to revenue, not just convenience. Forrester reports that 84% of marketers say phone calls convert at higher rates than any other lead channel. But here's the catch: Invoca’s research shows 79% of callers are rerouted at least once, which only increases frustration and the risk they'll hang up.
Smart forwarding—like routing a call to an AI assistant first—cuts down on those painful transfers and helps you capture more leads.
Real-World Examples of Smart Forwarding
Let’s look at how this plays out in practice for a couple of different service businesses.
A locksmith can forward all their after-hours calls to an AI agent like Marlie.ai. The AI gathers the caller's location and vehicle details, then instantly forwards only the qualified, urgent jobs to the nearest technician. This replaces a costly human call center with a far more efficient (and affordable) AI layer.
Similarly, a law firm can forward all new inquiries to an AI that screens and validates each lead before transferring them to an attorney. This simple step ensures lawyers only spend their valuable time on genuinely promising cases, which dramatically boosts their efficiency and, ultimately, their revenue. These are the kinds of strategies that turn call forwarding from a simple feature into a powerful business tool.
Integrate Call Forwarding With an AI Assistant
Sending calls to a standard voicemail or a colleague’s phone is fine, but it’s a defensive move. Integrating call forwarding with an AI assistant is where you go on offense. This is how you graduate from simply catching missed calls to building an automated, 24/7 front desk that actively works for you.
The setup is surprisingly simple, yet the impact on your business can be massive.
An AI assistant like Marlie.ai doesn't just record a message; it has a conversation. It can answer common questions, schedule appointments, and qualify new leads on the spot, all without a human lifting a finger. This simple shift turns call forwarding from a passive backup plan into an active, intelligent system.
Unlocking the Power of AI-Powered Forwarding
The real magic happens when you forward calls to a system that’s built to handle specific business tasks. For any service business—plumbers, lawyers, roofers—where every single call is a potential job, this is a total game-changer.
Think about it: an AI receptionist for small business can field up to 80% of routine inquiries. This frees you and your team to focus on the billable work that actually generates revenue.
I saw this firsthand with a law firm that was drowning in new client calls. They forwarded their main line to an AI, which then screened every inbound lead, gathered essential case details, and scheduled initial consultations automatically. That one change generated an extra $20,000 in revenue in just two months. Why? Because no qualified lead ever slipped through the cracks again.
This isn't just about answering the phone. It's about creating a system that intelligently manages your customer interactions, ensuring every caller gets an immediate, helpful response, day or night. That consistency builds trust and captures opportunities you would otherwise miss.
For a small HVAC or towing company, this kind of capability is huge. Instead of buying expensive hardware or hiring a full-time receptionist they can't afford, the owner just sets their main business number to forward to an AI after two rings.
With an AI answering in under two seconds and handling 60-80% of routine calls, owners can finally treat call forwarding as the primary bridge between every caller and an always-on front desk.
Setting Up Your Forwarding to Marlie.ai
We designed the process to be dead simple. Once you have your dedicated Marlie.ai number, you just use your phone or carrier's standard call forwarding features to redirect your calls to it. That's it.
Here’s a peek at the dashboard where you can manage your AI’s settings.
The interface lets you customize how the AI interacts with your callers and view call logs in real time.
You can set up rules based on what you need:
- Unconditional Forwarding: Send all calls directly to your AI assistant, 24/7. Perfect for when you want a completely hands-off front desk.
- Conditional Forwarding: Only forward calls when your line is busy or you don’t answer. This makes the AI your reliable backup.
This setup ensures that even when you're on a job or with a client, your business is still actively engaging new leads. To explore how this fits into a bigger picture, you might consider how an AI automation agency can streamline other parts of your business.
By integrating call forwarding with an AI, you’re not just managing calls—you’re building a more resilient and profitable business.
Troubleshooting Common Forwarding Problems
Even with what seems like a perfect setup, technology can have a mind of its own. When call forwarding starts acting up, it’s almost always due to a simple, easy-to-fix issue. Knowing the usual suspects can save you a ton of frustration from missed calls and keep everything flowing smoothly.
One of the most common complaints I hear is about calls going straight to voicemail instead of the number they’re supposed to forward to. This usually happens when the "forward when unreachable" setting is steamrolling your other rules. For instance, if your phone hits a dead zone with poor service, the carrier might instantly see it as "offline" and punt the call to voicemail before any of your other forwarding instructions even get a chance to kick in.
Another one is a noticeable lag before the forwarded call actually connects. This can be especially frustrating if you're routing calls internationally.
Calls Go Straight to Voicemail
If callers are landing in your voicemail instead of reaching the forwarded line, the first thing to look at is your conditional forwarding setup. The rules for when you’re "busy," "unanswered," or "unreachable" can sometimes get tangled and conflict with each other.
Pro Tip: The easiest way to diagnose this is to turn off all forwarding completely. Then, turn back on just the one rule you absolutely need. If it works, start adding your other rules back one by one until you find the culprit. It's a simple process of elimination.
Also, take a look at the number of rings you've set before a call forwards. If it's too high, your phone's own voicemail might beat it to the punch. I've found that setting it to 2-3 rings is the sweet spot. If you want to really get into the weeds, we break down these rules in our guide on conditional call forwarding.
Fixing Latency and Dropped Calls
That annoying delay before a call connects? It often comes down to the route the call has to take. Every "hop" from your carrier's network to the final destination adds a tiny bit of latency. When you're forwarding calls across borders, those tiny delays can really add up.
Thankfully, modern call forwarding isn't what it used to be; it’s a cloud-based, global machine. Top providers now offer local numbers in over 160 countries, all running on networks with 99.999% uptime to route calls around the world with almost no downtime. The whole international calling market is projected to hit $2.38 billion by 2029 as more businesses need to connect globally. With over two-thirds of contact centers moving to the cloud, call forwarding has become the essential glue that lets an AI receptionist like Marlie answer any number, 24/7. You can see more on this in the global call control market report.
To fix latency, the first thing to do is double-check the forwarding number. Seriously. A single wrong digit can send a call on a wild goose chase through the network. If the number is correct and you're still getting delays, it might be time to ring up your carrier, as the problem could be on their end.
Your Call Forwarding Questions, Answered
Even after walking through the setup, a few specific questions always pop up. It's one thing to know how to do it, but another to understand the little details that can trip you up. Here are the most common ones we hear from business owners, with straight answers based on real-world experience.
Can I Forward My Landline to My Cell Phone?
Yes, you absolutely can, and honestly, it’s one of the most powerful moves a small business owner can make. This is how you untether yourself from the office while making sure you never miss a beat. It keeps your established business number in front of customers, but gives you the freedom to answer a call from a job site, your truck, or anywhere in between.
The process is usually pretty simple. You’ll pick up your landline handset and dial a special code—something like *72 is common. After a beep or a prompt, you just punch in the 10-digit cell phone number where you want the calls to go. It’s always smart to double-check with your landline provider for their exact code, but it's rarely more complicated than that.
This simple trick is a game-changer for maintaining a professional image. Customers call the number they've always known, but you get the flexibility to run your business from anywhere.
Does Call Forwarding Have Hidden Costs?
Most of the time, the feature itself is baked into your plan, whether you're with a mobile carrier or a business VoIP provider. You probably won't see a line item that says "call forwarding fee."
Where you need to pay attention, though, is how your minutes are counted. This is the detail that catches people by surprise. With some plans (especially older ones), a forwarded call can actually use minutes on both the original line and the phone it's forwarded to. And if you're forwarding calls to an international number, you should definitely expect to see extra per-minute charges.
To avoid a nasty surprise on your next bill, take five minutes to check with your provider. A quick call or live chat is all it takes. Just ask them these three things:
- Is the call forwarding feature itself free with my plan?
- How are minutes billed when a call is forwarded?
- Are there any extra fees for forwarding to different number types, like a mobile phone or an international number?
Getting this cleared up ahead of time is well worth the effort.
How Can I Be Sure My Calls Are Actually Being Forwarded?
The easiest, most foolproof way to know it’s working is to just test it. Grab a friend's phone or use another line and call your business number. If the right phone rings—the one you set up for forwarding—you're good to go.
Many smartphones also give you a little visual confirmation. On an iPhone or Android, look up at the status bar at the very top of your screen. You might see a small icon of a phone with an arrow next to it, which is the universal sign that call forwarding is active.
If you want to get a bit more technical, some carriers have status codes you can dial. For anyone on a GSM network (like AT&T or T-Mobile), you can usually dial *#21# and press the call button. Your screen will then display the number your calls are being forwarded to, confirming the setting directly from the network.
