So now we know what VoIP does—but how does it do it? Let’s take a moment to talk about how, exactly, VoIP technology works its magic.
Voice over IP technology converts analog voice signals (aka your voice) into digital signals. These digital signals are compressed into tiny data packets that can be sent over the internet to a receiving phone number at super-fast speeds.
Once your business VoIP provider sets up the connection between you and your intended recipient, the data packets are sent, received, and decompressed at the other end. This means the receiver of your call can hear you speaking in real time—without any traditional telecoms coverage, landline phones, or need for a cell phone network. All you need is high speed internet and to have access to HD phone calls.
Neat right?
So, here’s what you’ll need to do if you want to call somebody using Voice over Internet Protocol:
- You’ll need to sign up with a VoIP vendor (we recommend 8x8). Make sure to do some research before settling on a vendor. VoIP providers differ in terms of their pricing plans and level of service, so look for one that can meet your current and future business needs.
- You’ll need to get a) a VoIP-compatible phone, b) a VoIP mobile app downloaded onto your smartphone or tablet, and c) computer software installed on your personal computer or laptop to ensure you can use VoIP with all of your preferred devices.
Here’s an example of VoIP in action.
Imagine that an employee working from home in your business needs to make a follow up call to a customer. Said employee does not need access to a VoIP-enabled desk phone at your office to make this call.
Instead, they can call the customer directly from their own computer or mobile device. All the employee has to do is open the VoIP app and dial out to the customer as they normally would do using any other telephone setup. The digital signals will travel through the Local Area Network (LAN) to your VoIP service provider, which will then establish the call in real-time.
So, what makes up a modern VoIP phone system?
The great thing about VoIP—especially hosted VoIP—is that it can require very little physical infrastructure, making it an extremely flexible and scalable solution. But even a VoIP system requires one or two essential components, those being:
- Stong internet connectivity and
- A device that lets you make VoIP calls
Let’s take a look at those in more detail.
For VoIP to work at all, you need to have a stable connection to the internet. Whether you’re using broadband, DSL, cable, or data, it’s important to make sure you have reliable internet connection before deploying your VoIP telephone system.
The best options for businesses are DSL, cable, ethernet, or fiber internet solutions. For VoIP to work effectively you’ll need that network to be high-speed, secure, and equipped with sufficient bandwidth to support the number of devices that you plan to connect to your system.
As a general rule, VoIP requires an average bandwidth of around 100 Kbps per device. But you may need more (or not so much) depending on your business’ unique usage requirements. Make sure you talk to your Internet Service Provider (ISP) if you need to upgrade your plan.
Thanks to internet calling, employees these days don’t have to be shackled to their desks 24/7. Remote and hybrid working options are more and more accessible thanks to Voice over IP technology.
Good internet connectivity is the lifeblood of VoIP so, whatever you do, prioritize setting up super fast broadband in your office. If you have remote workers, you’ll want to make sure they have the means and capacity to access a reliable internet network, whether it’s in the form of a home fiber connection or a secure Wi-Fi network.
As great as VoIP is, you’ll still need a device to make calls using it. There are a few options to choose from: an IP phone, a softphone, or an analog device supported by a telephone adapter.
- IP phones: All VoIP devices are, by nature, IP phones. Some may be designed to work like conference phones. Others look more like regular desk phones or multi-line phones for receptionists. Either way, these types of phones can be configured to receive calls routed to it care of the VoIP-powered PBX system.
- Softphone: For many modern businesses, physical desk phones are a thing of the past. For those who want to do away with traditional phone systems, VoIP calls can be facilitated via software supplied by their chosen VoIP vendor. This is what’s known as a softphone. A softphone allows you to dial out and take incoming calls using a virtual phone interface with designated phone numbers and caller IDs from any device. Simply download your softphone app onto your device of choice (smartphone, laptop, computer, tablet) and get up and running in a matter of minutes.
- Analog telephone adapter: Lastly, if you want to keep your old telephones but still want to mobilize VoIP in the office, then you’ll need an analog telephone adapter (or ATA). An ATA allows your analog phone to function with VoIP.
Typically you’ll only be able to have basic call functionality in this way. Nonetheless, this can be an affordable option for businesses that don’t want to get rid of their legacy hardware immediately. It’s also a great way to transition to VoIP.
