Your phone system

Your work number, wherever you happen to be

Take the office line with you. The Greencaller app rings on your phone over 4G, 5G or wi-fi, and calls you make go out from your business number — not the mobile number you would rather keep to yourself.

The office line, on the phone in your pocket

Same number, same history, wherever the job takes you.

Answer anywhere, on any network

In the van, on site, on a train or working from the kitchen table. If you have signal or wi-fi, the office line rings, and the caller has no idea where you are.

Dial out as the business, not as you

Outbound calls show your company number, so customers recognise it, call it back and reach the whole team instead of one person's mobile.

Your personal number stays personal

One handset, two identities. When you finish for the day you go off duty in the app, and the line rings whoever is on next rather than you.

The same history as everyone else

Calls, texts, notes and summaries sync the second they happen, so the person picking up next can see what was said whether it happened on a desk phone or a mobile.

Push that actually arrives

The app wakes properly for an incoming call, so you get a ringing phone rather than a notification about a call you have already missed.

Common questions

Or just ring us on 0330 460 9000 and ask.

Which devices does the app run on?
iPhone and iPad on iOS 16 and above, and Android 10 and above. There are matching desktop apps for Mac and Windows, plus the web app, and one account follows you across all of them.
Does it drain the battery?
No. The app sits idle and is woken by a push notification when a call comes in, rather than holding a connection open all day.
Can I use it without the app at all?
Yes. If you would rather not install anything, your Greencaller line can simply ring your ordinary mobile number instead — you just lose the shared history and the ability to dial out as the business.
What happens on a bad connection?
The app will tell you before you answer if your connection is too weak, and can hand the call to your mobile network instead so it still gets picked up.
