Updated 23 October 2026 · Advinne editorial team · 8 min read

Choose between a softphone and a desk phone for your business, considering flexibility, cost, and setup.

A softphone and a desk phone are two different types of phone systems for businesses and individuals. A softphone is a software-based phone system that runs on a computer or mobile device, while a desk phone is a physical phone connected to a traditional phone line. Choosing between the two depends on your specific needs and preferences.

Quick answer

When choosing between a softphone and a desk phone, consider the following key differences:

Flexibility and mobility

Softphones are software applications that run on computers or mobile devices, allowing users to make and receive calls from anywhere with an internet connection. This flexibility is a significant advantage for remote workers or those who need to make calls from different locations. Desk phones, on the other hand, are physical devices connected to a specific location and require a dedicated phone line.

Cost and setup

Softphones often require a one-time purchase or subscription fee, while desk phones may require a higher upfront cost for the device itself. However, desk phones can provide a more straightforward setup process, as they don't require a computer or internet connection.

How each option works

Softphones

Softphones are software applications that allow you to make and receive calls on your computer or mobile device using the internet. They typically require a headset or speakerphone and a stable internet connection to operate. Softphones can be downloaded and installed on most devices, and many providers offer softphone apps for mobile devices.

• Softphones often require a VoIP service provider to function.
• They can be used with a variety of operating systems, including Windows, macOS, and mobile devices.
• Softphones can be used with a range of internet connections, including broadband and mobile data.

Desk Phones

Desk phones, also known as VoIP desk phones, are physical devices that connect to your internet connection and allow you to make and receive calls. They often require a power source and a physical connection to your router. Desk phones can be connected to a computer or used as a standalone device.

• Desk phones can be connected to a router using an Ethernet cable.
• They often require a power source, but some models can be powered via USB.
• Desk phones may require a separate subscription to a VoIP service, such as Stay connected anywhere with a VoIP desk phone and WiFi.

What each offers

Softphones and desk phones cater to different needs and preferences. A softphone is a software-based phone system that runs on your computer or mobile device, providing flexibility and mobility. A desk phone, on the other hand, is a physical device connected to a physical network, ideal for those who value a traditional phone experience.

Key features and benefits

• Mobility: Softphones allow you to make and receive calls from anywhere, while desk phones are tied to a specific location.
• Cost and setup: Softphones often require less initial investment and setup, whereas desk phones may need more infrastructure and installation costs.

• Call quality: Softphones can provide better call quality and more advanced features, such as video conferencing and screen sharing, but may be more prone to connectivity issues.
• Scalability: Softphones can be easily scaled up or down to accommodate changing business needs, while desk phones may require more hardware and setup to accommodate growth.

Which should you choose?

Consider your work style, communication needs, and budget when deciding between a softphone and a desk phone. Ask yourself:

• Is your team mostly remote or mobile? A softphone might suit you better, as it allows for flexibility and can be used on a variety of devices.
• Do you have a dedicated office space with a traditional phone system? A desk phone might be the better choice, as it provides a physical connection to the office network.
• Are you looking for cost savings? Softphones are often more affordable, as they don't require a dedicated hardware purchase.
• Do you prioritize high-quality audio and video conferencing? A desk phone might offer better performance in this area.

Assess your communication needs

• Do you frequently make or receive international calls? A softphone might be more convenient, as it can easily integrate with cloud-based services.
• Do you have a large team or multiple departments? A desk phone system can provide a more centralized and organized communication experience.
• Are you concerned about data security? A desk phone might be more secure, as it's less vulnerable to hacking and eavesdropping.

Ultimately, the decision between a softphone and a desk phone comes down to your specific needs and preferences.

How to switch

Transitioning from a desk phone to a softphone

To switch from a desk phone to a softphone, you'll likely need to upgrade your hardware and software. First, ensure your computer or mobile device is compatible with the softphone software you've chosen. Next, purchase a USB headset or speakerphone to replace your desk phone's handset.

Upgrading your setup

• Replace your desk phone with a softphone app or software on your computer or mobile device.
• Invest in a high-quality USB headset or speakerphone for clear audio and hands-free use.
• Check your internet connection speed to ensure it can handle the increased data requirements of a softphone.
• Update your router and network settings to support VoIP traffic.
• Consider investing in a VoIP adapter if you have a traditional landline phone.

Transitioning from a softphone to a desk phone

Switching from a softphone to a desk phone typically requires a simpler process. You'll need to disconnect your softphone software and uninstall any relevant apps. If you're using a VoIP adapter, you'll need to remove it and reconnect your traditional landline phone. Check your desk phone's compatibility with your existing network and internet setup before making the switch.
