Types of VoIP phones 

Choosing a VoIP phone might appear a challenging task with so many options available. By organizing the various types, the decision-making process becomes much simpler. Let’s explore:

  1. Hardware VoIP Phones
  2. Softphones
  3. Mobile VoIP Apps
  4. Video VoIP Phones

Each type has its unique benefits and features, catering to distinct needs within the marketplace. 

1/ Hardware VoIP Phones

How a hardware VoIP phone looks like

Hardware VoIP phones resemble traditional telephones but are adapted to handle voice data. These physical devices connect directly to a VoIP network through Ethernet or WiFi, transforming analog voice signals into digital data that is transmitted over the Internet.

They are equipped with advanced features that are not typically found on regular phones, such as caller ID, voicemail, call transfer, touch-screen interfaces, and multiparty calling – these phones are designed for professional settings. They deliver exceptional call quality and reliability, making them ideal for offices requiring multiple phone lines. 

Hardware VoIP phones also provide a unified integration into a company’s existing communication infrastructure, combining traditional ease of use with the benefits of modern VoIP technology.

2/ Softphones: 

Softphones operate as software applications rather than physical devices. They are adaptable for installation on a range of devices such as PCs, and smart mobile devices, transforming them into communication hubs. 

Softphones use the device’s built-in microphone and speakers or can be used with connected headsets, to make and receive voice calls over the internet. This adaptability establishes them as a prime choice for businesses that prioritize mobility and cost-efficiency. Since they require no additional hardware, softphones can significantly reduce overhead costs associated with traditional phone systems. 

Additionally, softphones integrate easily with business applications such as CRM systems and offer a range of features similar to hardware VoIP phones – including voice and video calls, voicemail, caller ID, and conference calling enhancing workflow efficiency. 

3/ Mobile VoIP Apps

Mobile VoIP Apps include a broad category of applications specifically designed for use on smartphones and tablets, facilitating VoIP calls directly from mobile devices. These apps use the existing internet connection, either through WiFi or mobile data networks, to place and receive calls, thereby avoiding the traditional cellular networks. 

This approach not only significantly reduces the cost of mobile communication, especially for international calls and roaming, but it also introduces a new level of flexibility and mobility in communication.


You can download and install VoIP apps like WhatsApp, Skype, or Viber on your mobile devices that offer a wide range of features beyond simple voice calls. These include video calls, text messaging, file sharing, and integration with business applications, providing a unified communication experience that is not tied to a specific location or device.

Related Stats:

Every day, 74% of employees indicate that they utilize VoIP applications on their mobile devices to conduct business calls.

4/ Video VoIP Phones

Video VoIP phones incorporate advanced communication technologies to facilitate both voice and video calls over the Internet. Unlike traditional VoIP devices that only support audio communication, Video VoIP phones enable you to engage in face-to-face interactions, leveraging high-quality video alongside clear audio. 

This type of phone system combines the reliability and clarity of VoIP calling with the personal touch of video conferencing, making it an essential tool for businesses looking to enhance collaboration and connectivity. 

With Video VoIP phones, your business can conduct virtual meetings, interviews, and discussions with a level of engagement that closely resembles in-person communication.

Why are there two network ports on VoIP phones 

VoIP phones are equipped with two network ports to enhance their functionality and integration within a network environment. This dual-port configuration allows one port to connect to the local area network (LAN), while the other connects directly to a computer or other network device. 

This arrangement serves several purposes. Firstly, it simplifies the network infrastructure by reducing the need for additional network switches or ports, especially in environments where desk space is at a premium. 

Secondly, it ensures that both the VoIP phone and the computer can access the network through a single LAN connection, facilitating efficient data transfer and communication. 

This setup not only optimizes the use of network resources but also minimizes cable clutter, making it a refined solution for both home and office settings.

How to turn your old phone into VoIP

Transforming an old phone into a VoIP device is a cost-effective way to repurpose the technology you already own. Here’s how to get started:

  1. Check Compatibility: First, ensure that your old phone can connect to the internet, either via Wi-Fi or through an Ethernet adapter. This is crucial, as VoIP services require an internet connection to function.
  2. Select a VoIP Provider: Choose a VoIP service provider that meets your needs, whether it’s for home or business use. Evaluate aspects like pricing, functionalities, and customer service. Sign up for the service and take note of the credentials provided, as you’ll need them for setup.
  3. Acquire an Analog Telephone Adapter (ATA): An ATA converts the analog signal from your old phone into digital data that can be sent over the internet. Purchase an ATA that is compatible with your VoIP provider’s service.
  4. Configure the ATA: Connect the ATA to your internet router and your old phone. Follow the setup instructions provided with your ATA device to configure it using the credentials from your VoIP provider. This typically involves accessing a web interface and entering details such as your VoIP username, password, and server information.

Once configured, make a test call to ensure everything is working correctly. You should be able to place outgoing calls from your previous phone and receive calls with your new VoIP number.

Frequently Asked Questions
