Softphone vs Desk Phone: Which Does Your Business Need?
A softphone is an app that turns a laptop, PC or mobile into a business phone. A desk phone is a physical handset that plugs into your network. Most businesses need both. Desk phones suit reception, shared spaces and heavy phone users. Softphones suit hybrid staff, people who travel and anyone who only takes the odd call. The right mix depends on who makes calls, where they work and how much a missed call would cost you.
What Is a Softphone?
A softphone is software that lets you make and receive calls through your business phone system using a computer or smartphone, with a headset or the device's own microphone and speaker. It uses your business number and extension, so callers can't tell the difference. Our guide to what a softphone is covers the basics, and our 3CX guides show what this looks like in practice, including the mobile app and the Windows desktop app.
What Is a Desk Phone?
A desk phone is a dedicated handset with its own screen, keypad and speaker. It connects to your network by ethernet cable (or occasionally Wi-Fi) and registers to your phone system. Cordless DECT handsets work the same way, with a base station doing the connecting. Our guide to DECT and repeaters explains how cordless coverage works.
Softphone vs Desk Phone: Key Differences
| Softphone | Desk phone | |
|---|---|---|
| Upfront cost | Low. Usually just a headset | Higher. Handset, plus PoE or a power supply |
| Works from anywhere | Yes, with an internet connection | Only where the handset is plugged in |
| Call quality | Depends on the headset and the device | Consistent, with a purpose-built speaker and microphone |
| Reliability | Depends on the laptop or phone it runs on | Very dependable once installed |
| Ease of use | Good for people who live on their computer | Familiar for anyone who just wants to pick up and dial |
| Best for | Hybrid, remote and mobile staff | Reception, shared desks, warehouses, shop floors |
When a Desk Phone Is the Better Choice
- Reception and front desk. A receptionist handles constant calls, transfers and busy lamp fields. A physical handset with dedicated keys is quicker and less error-prone than clicking through an app.
- Heavy phone users. Sales and support teams on calls all day benefit from a handset with good audio and a headset socket.
- Shared or fixed spaces. Meeting rooms, stockrooms and workshops don't need a laptop to take a call.
- Staff who don't want to log in to anything. Some people simply want to pick up a phone and dial.

When a Softphone Is the Better Choice
- Hybrid and remote staff. Calls follow the person, so they can answer on a laptop at home without giving out a personal number. See how VoIP is powering hybrid working for more.
- Occasional callers. If someone makes a handful of calls a day, a headset costs far less than a handset.
- Travelling staff. A mobile app means business calls on the road, using the business number.
- Growing teams. Adding a user is quick when there's no hardware to buy, configure and deliver.
Our setup guide for remote and hybrid teams covers the features worth switching on.
What Are the Downsides of Each?
Softphones
- They depend on the device. If the laptop freezes, updates or runs out of battery, so does your phone.
- Call quality depends heavily on the headset. A cheap one makes the whole system sound poor.
- Notifications can get lost behind other windows when someone's busy in another app.
Desk phones
- They cost more upfront, and every handset needs a network port and power. A PoE switch saves on power adapters.
- They're tied to a desk. Staff who move around get less from them.
- Moving offices or reshuffling teams means physically moving handsets.
Can You Use Both?
Yes, and most businesses do. A common setup is a desk phone for reception and heavy callers, a softphone on every laptop for flexibility, and the mobile app as a backup. All three can register to the same extension, so a call rings everywhere and whoever answers first takes it. Our guide to how many handsets you can have on one VoIP system covers the licensing side.
What About Power Cuts and Internet Problems?
Both rely on your internet connection, so both stop working if it fails. A laptop softphone may keep going on battery during a power cut, but only if your router and broadband are powered too. Desk phones usually stop unless they're on a UPS. Our guide to what happens in a power cut explains how to build in a backup.
How to Decide
- List each role and how many calls it handles in a normal day.
- Mark who works from one fixed desk and who moves around.
- Give desk phones to reception, heavy callers and shared spaces.
- Give everyone else a softphone and a decent headset.
- Check your network and bandwidth can handle the peak number of calls. Our guide to VoIP bandwidth requirements helps here.
If you're on Microsoft Teams, the same logic applies. Our guide to which handsets work with Teams Calling explains what's certified.
Frequently Asked Questions
Is a softphone cheaper than a desk phone? Usually, yes. A good headset costs much less than a handset, and there's no network port or power supply to provide. The saving is bigger across larger teams.
Is call quality worse on a softphone? Not necessarily. With a decent headset and a stable connection, a softphone sounds just as good. Poor quality almost always comes from a cheap headset or a weak network, not the app itself.
Can I use a softphone and a desk phone on the same number? Yes. Most systems let one extension register on several devices at once, and all of them ring when a call comes in.
Do I still need desk phones if everyone works from home? Not necessarily. A fully remote team can run entirely on softphones and mobile apps. Many businesses keep a handset or two for reception or the office.
Which is more secure? Both are secure when set up properly. Softphones add the risk of a lost or compromised laptop or phone, so it's worth using device passwords and, where possible, remote wipe.
