What a softphone actually is, and when you need one

Somewhere between "we all just use our mobiles" and "we have a phone system" sits the softphone. It is worth understanding properly before you pay for one, because for a lot of small teams the honest answer is that they do not need it yet.

It is a line, not an app

The confusing part is that a softphone looks like an app, so people compare it to WhatsApp or Teams. It is not that. A softphone is a real telephone line — it has a number, it can call any phone in the world, and anyone can call it back. The only difference is that the handset is a browser tab instead of plastic on a desk.

That distinction matters for one practical reason: because it is a real line, it is regulated like one. Numbers in most of Europe require proof of a business address before they can be issued, and that paperwork is why a new line takes a day rather than a minute.

What you actually gain

• The number belongs to the company, not to whoever is holding the phone. People leave; the number stays.
• Calls land on the customer record by themselves, so nobody types a call log.
• You can call from a laptop in another country and still show a local number.
• A manager can see who is on a call, who is wrapping up and who is free, without walking the floor.

When a mobile is the better answer

If your team makes a handful of calls a day, mostly to people who already know them, a softphone adds cost and a browser tab for very little. The case for one starts when calling is a volume activity — when somebody has a list in front of them and the number of conversations per hour is the thing you are trying to move.

The other honest case against is connection quality. A softphone is only as good as the network under it. On a stable office connection it is indistinguishable from a desk phone; on hotel wifi it is worse than a mobile.

What it costs

Two things get priced, and they are often confused. The line itself — the ability to make and receive calls — is one cost. The minutes are another, billed by the destination. A per-seat price that does not mention minutes is quoting you half the bill.
