Fixed on mobile

With a fixed number on your mobile, your business stays reachable on a professional number, wherever you are. Incoming calls to your business number arrive on your mobile phone via the Linphone app or direct forwarding over the mobile network. Customers simply call your business number and you answer—whether you are in the office, on the road, or working from home—without them noticing any difference.

For many UK businesses, sole traders, and freelancers, a fixed business number is essential because it combines the trusted impression of traditional landline telephony with the flexibility of mobile working.

  • Receive business calls on your mobile
  • Great for field teams and people on the move
  • Keeps your private number private

Do you want to stay reachable for business on a fixed number, even when you’re on the move? Then you’ve found it! With a fixed number on your mobile, incoming calls to your fixed business number simply arrive on your mobile phone. Customers call your fixed number and you pick up anywhere, without them noticing any difference.

You decide how the calls come in. Through the Linphone app on your smartphone, or through a direct forward over the mobile network to one or more mobiles — whatever suits each team member best.

That direct forward over the mobile network doesn’t depend on an app or an internet connection. So every call simply comes through, unlike the consumer apps that many providers offer.

You choose the number that fits your business: a national number or a regional number that matches your market. A fixed number builds trust with customers, and your private number stays private.

You don’t need to have a fixed line installed or maintain a physical exchange. So you come across as professional for a low monthly fee, with no upfront installation costs.

Voicemail, forwarding, opening hours and the ring order you set yourself from the portal. And you keep your existing fixed number thanks to number portability, so customers keep calling the same number they already know.

It suits freelancers and small businesses without their own office, entrepreneurs who are often on the road, and teams working hybrid. One shared business number across several mobiles means the right person picks up, without transferring the caller.

Request your number and we’ll get to work for you.

CallFactory web interface team dashboard

How it works

You order an 0800, 0345, or regional number such as 020 or 0161, or transfer your existing fixed number using number portability so your customers continue calling the familiar number they already know.

After ordering, you set up in your dashboard how calls arrive: via the Linphone app on your smartphone or computer, or direct forwarding over the mobile network to one or more mobile phones. You set the call order, decide what happens when nobody answers, and switch between destinations without changing your number.

Within a few days your number is live and you are handling business calls from your smartphone, while customers see only your fixed number.

What sets our solution apart

Many providers offer an app designed for consumers with business needs, where you depend on that one app and a good internet connection. CallFactory specialises in business telephony and offers both the Linphone app and direct forwarding over the mobile network, so you choose per team member which method works best for their situation.

Install Linphone on your smartphone and on your Mac, Windows, or Linux computer, turning your desktop or laptop into a full business phone where you take and make business calls on your fixed number. At your desk you call via a headset on your computer, on the road you switch seamlessly to your mobile, and working from home you simply continue on the same business number without changing anything in your setup.

Beyond basic call forwarding, you have access to an interactive voice menu that automatically routes callers to the right department, call recording for training and evidence, voicemail-to-email and detailed real-time call analytics.

Through your online phone system you manage all settings yourself, from opening hours to call groups and from voicemail to forwarding options, so you decide how the caller is helped.

Which businesses benefit most

Fixed on mobile suits freelancers and consultants who want professional availability on their own business number without a physical landline. Small businesses without a dedicated office use it to project the same trusted image as established firms with premises and a reception.

Entrepreneurs who spend much time on the road ensure they never miss a customer or supplier because they are away from their desk. For teams working flexibly or hybrid, one shared business number on multiple mobile phones means the right person picks up without the caller needing to be transferred.

Everything at a glance

Available number types: 0800, 0345, 020, 0161 and other regional numbers, so you choose the number that fits your business and market.

Forwarding options: to a mobile number, a desk phone, a softphone or voicemail, in any order and with any fallback combination you need.

Extra features: interactive voice menu, call recording, real-time analytics and voicemail-to-email, so customers are guided to the right information quickly even outside office hours.

Technical requirements: no special equipment needed; any mobile phone works with the service, and the Linphone app also runs on Mac, Windows and Linux so your computer becomes a full business phone.

Management: 24/7 access to your online dashboard for all settings.
