What is a VoIP phone?
Voice over Internet Protocol, or VoIP, is a technology that allows phone calls to take place over the internet. IP phones, also known as VoIP phones, come in a number of varieties, depending on an organization’s particular needs.
Among a broad spectrum of VoIP office phones, there are both corded and cordless varieties for businesses to choose from, for extra mobility during calls. There are also VoIP phones that are specifically designed for conference calls, have speakerphone functionality, some that offer video calling, and others that work best in call centers.
In this buying guide, we’ll be taking a look at the hardware behind the best VoIP phones on the market for your small business. Although VoIP services play an important role in the quality of a company’s phone networks, the hardware underpinning a VoIP business phone system determines the kind of functionality that will be available.
How to choose the best VoIP phones for you?
When choosing the best VoIP phones for your business, begin with assessing how easy it is to set up and use. You'll then want to check what type of display it has, how much power it consumes, the voice quality, video calling features, and Ethernet cable support.
Consider the quality of the device's hardware, latency, recording capabilities, and support for multiple VoIP accounts. Not all models come with power adapters, so you'll want to look out for that too.
Lastly, consider how easy it is to train your staff on the VoIP phone, whether there's wireless handset support, and the pricing.
How does a VoIP phone work?
VoIP phones work by converting analogue voice signals into audio data packets. The data packets are delivered via broadband rather than by traditional PSTN and ISDN telephone networks, means that VoIP services are usually cheaper and more scalable than traditional Private Branch Exchange (PBX) phone networks and offer advanced telephony features.
What is the difference between VoIP and IP telephony?
Although often used interchangeably, IP phones and VoIP phone systems have a subtle difference: VoIP phones use the public Internet to carry voice traffic while an IP phone uses a private data network for outbound calls.
Regardless of the intricacies of the particular system you chose, both VoIP and IP phones offer a number of advantages over traditional phone lines.
Can I use my smartphone or a normal landline phone for VoIP or do I need to buy a special phone for VoIP?
One of the major benefits of VoIP telephony is its flexibility and this extends to the type of handsets that are compatible with VoIP solutions. The short answer to whether a smartphone or normal landline phone can be used for VoIP solutions is yes. However, there may be some tricky configuration involved and a few features may not necessarily be available.
If businesses or individuals want to use VoIP services with their normal landline, they will first need to purchase some sort of adapter to connect their phone to the internet. Usually, this connects your phone to your wireless router using an Ethernet cable. Users will then need to enter the IP address of their VoIP adapter using another internet-connected device, following the instructions that came with the adapter. Once the configuration is complete, individuals can use their ordinary analog phone to make and receive calls over the internet.
Thankfully, things are even easier when it comes to using a smartphone to access VoIP solutions. As smartphones already have the capability of connecting to the internet, using VoIP services is usually pretty straightforward. In fact, there are several VoIP providers that are specifically targeting the smartphone market, looking to take advantage of businesses adopting bring-you-own-device (BYOD) policies.
With a call routing feature in place, employees can continue using their personal smartphone while it will appear to callers and recipients as though they are using their work number or extension. Employees using VoIP services on their smartphone can use the company Wi-Fi instantly to gain access to the usual VoIP platform but can easily switch off VoIP functionality outside of contract hours to ensure they maintain a good work-life balance.
However, although it is possible to use an ordinary landline or smartphone to access VoIP solutions, that does not mean that businesses and employees will be able to receive an optimum service. The kinds of handsets reviewed above are specifically designed to work with VoIP solutions and have particular hardware features that make them well suited to some of the modern innovations that are generally included with VoIP platforms.
Although standard landline and mobile devices will work with most VoIP services, they may mean that you are overpaying for a VoIP solution if you cannot access all of its features.
How hard is it to use a VoIP phone?
For individuals new to the world of VoIP, there’s no need to be intimidated. The good news is that the task that you’ll be using the device for most often — making and receiving calls — is no more complicated than with an analog landline handset or smartphone.
The only aspect of most VoIP phones that may be difficult is the installation process, but the best VoIP service providers will help with this. Office VoIP users will need to make sure that they have a working internet connection, a router, and a PBX server before they get started on their VoIP journey. You’ll also need to select your IP phone, connect it to your network, and install your VoIP software.
Once your VoIP phone is all set up, how easy or hard it is to use will depend heavily on the types of features on offer. Modern VoIP phones come with a wide variety of features and a sizeable number of buttons - both physical and digital. It’s a good idea for new VoIP users to familiarize themselves with the instructions that come with their device before getting started.
That being said, most IP phones pride themselves on their ease of use, so individuals shouldn’t find using any VoIP phone particularly difficult. What’s more, customer support should be able to offer assistance if any is required.
