Key Considerations When Choosing a VoIP Handset
Choosing the right VoIP handset isn’t simply about selecting the phone with the most features. The best option will depend on how your employees work, the phone system you use and the functionality each user actually needs.
Compatibility With Your VoIP System
Before purchasing any handset, check that it is compatible with your chosen VoIP platform or hosted phone system. Not every handset supports every provider or feature, so compatibility should be confirmed before investing in new equipment.
Desk Phone or Cordless Handset?
Consider where the phone will be used. Employees who spend most of their day at a desk may prefer a traditional IP desk phone, while staff working across warehouses, workshops, retail environments or larger offices may benefit from a cordless DECT handset.
Call Volume and Line Requirements
Receptionists, sales teams and customer service staff may need to manage several calls or extensions at once. Look at the number of supported lines, programmable keys, BLF functionality and call-handling features rather than choosing the same handset for every employee.
Headsets and Connectivity
If employees regularly use headsets, check the connections supported by the handset. Depending on the model, this could include USB, Bluetooth or dedicated headset connections. Wi-Fi may also be useful where a wired network connection isn’t practical.
Power over Ethernet
Many business VoIP phones support Power over Ethernet (PoE), allowing compatible network equipment to provide both power and data through a single Ethernet cable. This can help reduce cabling around desks and simplify installation.
Your Network and Broadband
VoIP call performance also depends on the quality and configuration of your business network. The number of simultaneous calls, available bandwidth and other internet activity should be considered when planning your phone system.
Where appropriate, network features such as Quality of Service (QoS) can be used to prioritise voice traffic and help maintain consistent call quality.
Future Requirements
Think beyond the number of phones you need today. If your business is growing, opening additional locations or introducing more remote working, choosing equipment and a phone system that can accommodate future users can make expansion considerably easier.
VoIP Handset FAQs
What is the difference between a VoIP handset and a normal phone?
A VoIP handset connects to an IP-based phone system and uses your internet or business network to make and receive calls. A traditional telephone is designed to connect to a conventional telephone line. VoIP handsets can also provide additional business features such as programmable keys, call transfers, directories and headset connectivity.
Will any VoIP handset work with my phone system?
Not necessarily. Compatibility depends on the handset, your VoIP platform and how the system is configured. Always check that a handset is supported by your provider or phone system before purchasing equipment.
How many VoIP handsets does my business need?
This depends on how your team works. Some employees may need a dedicated desk phone, while others may be better suited to cordless handsets or software-based calling. You don’t necessarily need to provide every employee with the same type of phone.
Can I use a cordless handset with VoIP?
Yes. DECT VoIP systems allow employees to use cordless handsets while remaining connected to the business phone system. They can be particularly useful in warehouses, workshops, retail premises and larger offices.
Do VoIP handsets need to be plugged into a computer?
No. Most business IP phones connect directly to your network rather than through a computer. Depending on the model and your network setup, they may connect using Ethernet or Wi-Fi.
Do VoIP phones need their own power supply?
Not always. Many business VoIP handsets support Power over Ethernet (PoE), which allows both power and network connectivity to be delivered through an Ethernet cable when used with compatible network equipment. Other phones may require a separate power adapter.
Can I use a headset with a VoIP handset?
Many business VoIP phones support headsets, but the available connection varies between models. Depending on the handset, this could include USB, Bluetooth or a dedicated headset connection.
Which VoIP handset is best for my business?
There isn’t one handset that’s right for every business. Consider how frequently each employee handles calls, whether they need to move around the workplace, the number of lines or programmable keys required, headset requirements and compatibility with your phone system.
That last answer is particularly useful because it reinforces what the article is actually for rather than trying to claim one of the seven phones is universally the “best”.
