Fixed on mobile

With a fixed business number on your mobile, your Irish business stays reachable under a professional landline number wherever you are. Incoming calls to your fixed number arrive on your mobile phone via the CallFactory app or direct forwarding over the mobile network. Customers ring your business number and you answer—whether you’re at the office, out on a call, or working from home—without them noticing any difference.

For many Irish businesses and sole traders, a fixed telephone number is essential because it combines the trusted impression of a landline with the flexibility of mobile calling.

Why Irish businesses choose fixed on mobile

Discover how a fixed business number on your mobile keeps your team professionally reachable, wherever you work.

🏢

Professional image

A fixed business number builds far more trust with customers and prospects than a mobile number, improving your credibility instantly. Choose from a 1800 freephone or 0818 shared-cost number, or a regional number such as 01 (Dublin) or 021 (Cork) that reflects where your business operates.

📱

Reachable everywhere

With a fixed number on your mobile, your business stays reachable even when no one is in the office, so you never miss a customer or supplier call because you're away from your desk or working elsewhere.

💶

No expensive equipment

You don't need to install a landline or maintain physical phone hardware, so you can look professional at a low monthly cost with no upfront installation charges.

⚙️

Manage it yourself via the portal

Voicemail, call forwarding and opening hours are all managed through your online dashboard, so you adjust your team's availability on the spot without waiting for support.

How it works

You order a 1800 freephone, 0818 shared-cost or regional number such as 01 or 091 (Galway), or you bring your existing fixed number across via number portability, so customers keep ringing the number they already know.

After ordering, you configure how calls arrive in your CallFactory dashboard: via the Linphone app on your smartphone or computer, or via direct forwarding over the mobile network to one or more mobile phones. You set up a call queue, decide what happens when no one answers, and switch between destinations without changing your number at all.

Within days your number is live and you’re taking business calls from your smartphone, while customers only see your fixed number.

What sets our solution apart

Many providers deliver an app built for consumers with business needs, so you’re tied to that single app and a reliable internet connection. CallFactory specialises in business telephony and offers both the Linphone app and direct forwarding over the mobile network, so you choose per user which method suits the situation best.

Install Linphone on your smartphone and on your Mac, Windows or Linux computer, so your desktop or laptop becomes a full-featured business phone where you take and make calls under your fixed number. At your desk you call via a headset on your computer, on the move you switch seamlessly to your mobile, and at home you simply carry on with the same business number without any configuration change.

Beyond basic call forwarding, you have access to a selection menu that routes callers automatically to the right department, call recording for training and evidence, voicemail-to-email and comprehensive call insights in real time.

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

Which businesses benefit

A fixed number on mobile suits sole traders who want to be professionally reachable under their own business number without a physical landline. Small businesses without their own premises use it to project the same trustworthy image as established firms with an office and reception desk.

Entrepreneurs who spend a lot of time out of the office ensure they never miss a customer or supplier call because they’re away from their desk. For teams working flexibly or in hybrid setups, one shared business number on multiple mobile devices means the right person picks up the call without the caller needing to be transferred.
