What Is a Browser Softphone? A Guide to X-Web

Not every phone system needs a physical handset on every desk. A browser softphone puts full calling functionality directly into a web browser — here's what that actually means, how it compares to a desk phone or an installed softphone app, and how X-Web works in practice.

What Is a Browser Softphone?

A softphone is software that lets someone make and receive calls from a computer, phone or tablet instead of a physical desk handset. Most softphones are apps that need installing. A browser softphone goes a step further: it runs entirely inside a web browser tab, with nothing to download or install at all. Open the browser, log in, and the full calling interface — dialler, contacts, call handling — is right there.

Browser Softphone vs Desk Phone vs App-Based Softphone

• Desk phone — a physical handset, tied to a specific desk. Reliable and familiar, but inflexible: it doesn't move with the person.
• App-based softphone — installed software on a laptop or phone. More flexible than a desk phone, but still needs installing, updating, and managing on every device someone uses.
• Browser softphone — nothing to install at all. Works from any computer with a browser and an internet connection, which makes it particularly well suited to hybrid and remote working, hot-desking, or anyone who needs to make calls from a device that isn't their usual one.

What to Look For in a Browser Softphone

• Full call handling, not just dial and answer — attended and blind transfers, three-way conferencing, hold and mute. A softphone that only does the basics quickly becomes limiting.
• Chat and presence alongside calling — being able to message a colleague and see whether they're available, without switching to a separate app entirely.
• Contacts and call history built in — a proper directory and recent-calls list, not just a bare number pad.
• A layout that actually works for real use — a customisable, drag-and-drop dashboard suits people who use it heavily all day very differently to a stripped-back minimal interface.

How X-Web Works

X-Web is Plustel's browser-based softphone — a fully featured office phone that runs inside the browser, with calls, chat, transfers and voicemail all included and nothing to install. It goes beyond the basics most softphones offer: full attended and blind transfers, three-way conferencing, DTMF and hold/mute — everything a physical desk phone does, alongside built-in company chat and a customisable, drag-and-drop dashboard that can be arranged to suit how someone actually works.

Because there's nothing to install, X-Web works identically whether someone's at their usual desk, working from home, or logging in from a different machine entirely. The X-Web product page has the full feature breakdown and a look at the interface itself.
