Voice over Internet Protocol (VoIP) phone technology is very useful for business people, especially for small businesses. VoIP phones can be used from wherever employees are, and calls can be transferred seamlessly from office phones to mobile phones.
VoIP phones can also extend conversations from SMS to voice calls to video conference calls, all in the same application.
The flexibility, security, and affordability of VoIP phones are a technology to consider for your business. However, you have to adjust the types of VoIP that are suitable for your business.
In this article, you will be informed about the types of VoIP phones, which can add to your knowledge regarding VoIP.
5 Types of VoIP Phones
Voice-over IP technology is very versatile. This technology can be used on traditional desktop phones, USB headsets, conference phones, cell phones, and almost any computer, smartphone, or tablet that can download apps.
1. Standard desktop phones
Desktop IP Phones look and function similar to a traditional office phone. The difference is that these phones connect via an Ethernet cable and send voice calls using VoIP.
VoIP desk phones for business offer the most comprehensive range of features available. Most have an LCD screen that displays important information, including caller ID.
More advanced models have full-color touch screens for advanced productivity and can handle more than a dozen unique phone lines. Some models are equipped with Bluetooth technology, which allows users to use wireless headsets.
2. USB phones
USB Phones are simple devices that can be connected directly to a computer via USB. This device provides an easy and affordable VoIP phone solution for small business users.
USB phones generally don’t have LCD screens or any advanced features. Call management is usually handled via a computer connected to a USB phone. USB phones are generally used in conjunction with “softphones”, which are explained below.
3. Softphones
A softphone is a virtual phone that resides in a software application installed on your computer, smartphone, or tablet. Softphones are not tied to any physical location and therefore provide substantial flexibility.
Softphones can be used in combination with physical devices, such as headsets or USB phones. Many businesses simply run a softphone on a desktop computer, paired with a USB or Bluetooth headset.
4. Conference phones
VoIP conference phones are designed to improve voice quality during conference calls. This device has multiple microphones, and each microphone is electronically balanced to improve call clarity.
Conference phones are often V- or Y-shaped and have two to three separate audio speakers. Different speakers, combined with digital balancing, ensure that every sound in the room is conveyed clearly.
5. Video phones
Video Phones are similar to standard Desktop Phones. The only difference is that these phones have a built-in or USB-based camera along with a larger full-color display that is suitable for video calls.
With the growing popularity of software-based video calling, many business owners feel a dedicated video phone is unnecessary. However, these phones can still be useful additions to certain industries.
Is VoIP Secure?
VoIP calls are generally encrypted when using a reputable provider, protecting conversations from being intercepted the way older analog phone lines could be. Most business-grade VoIP services also support features like secure sign-on and call encryption protocols (such as SRTP) to keep communications private.
That said, since VoIP runs over the internet, it’s worth choosing a provider with strong security practices and keeping your network protected, just as you would for any other internet-connected business system.
Comparing the 5 Types of VoIP Phones
Here’s a quick side-by-side comparison to help you see how these five types stack up against each other:
| Type | Portability | Typical Cost | Best For |
| Standard desktop phone | Low (fixed to desk, wired) | Mid to high | Offices needing a full-featured, reliable primary phone line |
| USB phone | High (plug into any computer) | Low | Small businesses or remote workers on a tight budget |
| Softphone | Very high (works on any device with the app) | Low to none (often included with a VoIP plan) | Remote or hybrid teams needing flexibility across devices |
| Conference phone | Low (stationary, built for a room) | Mid to high | Meeting rooms and team calls requiring clear group audio |
| Video phone | Low to moderate | High | Teams or industries that rely heavily on face-to-face video calls |
Those are the types of VoIP phones that many people aren’t yet familiar with. Understanding the differences between them can help you choose the setup that best fits how your business actually communicates.
