Five signs your office has outgrown its phone line
Engaged tones, a shared mobile and no idea who called: five signs a growing office needs a real phone system, and what each one costs you.

Most businesses start with one number. It rings a phone on someone's desk, or the owner's mobile, and for a while that is enough. Then the team grows and the line does not. The problems arrive quietly, because a caller who could not get through rarely tells you.
Here are five signs that the line is now costing you work, and what an office phone system does about each.

1. Callers hear the engaged tone
One line carries one conversation. While it is in use, everyone else hears a busy signal and many of them call the next company on the list. A phone system holds several calls at once. On Filantis you choose a plan by how many calls you need at the same time, not by how many people you employ, so adding a tenth or a hundredth extension costs nothing extra.
2. Whoever is nearest answers
When every call lands on the same phone, your accountant ends up answering sales questions. A call menu lets the caller choose ("for sales, press 1"), and a ring group rings the whole team for that choice at once, so the call reaches someone who can help.
3. Calls after six o'clock disappear
An unanswered evening call is a lead you never knew you had. Set your office hours once, and after closing the system plays your message and takes a voicemail for the right department. Named holidays repeat every year without anyone remembering to switch a message on.
4. Staff give out their personal mobile numbers
It feels helpful until that person leaves and takes the customer's only contact number with them. With the mobile app, the office extension rings on the employee's own phone, so customers keep calling the company number. When someone leaves, you reassign the extension and the calls follow it.
5. Nobody knows who called, or what was said
A single line keeps no history. A phone system keeps a call report: who rang, when, who answered and for how long. With call recording you can also replay a disputed order or train a new hire on real calls. If you record, tell callers so in your greeting.
What moving costs you
Less than most owners expect. You keep your existing numbers by connecting the SIP trunk from your telecom provider. Calls ring desk phones, the browser and mobiles together, so you do not need a handset for every desk. And you decide where the system runs: in the cloud, on your own server or on an appliance.
If two or more of these signs sound familiar, the line is already costing you calls. The phone system has a free plan, so the cheapest way to find out is to create a workspace and point one number at it. The pricing page shows the sizes above that.
