onephone – The Telephony of the Future

onephone is the practical business smartphone solution with an integrated landline number. This way, your employees are always reachable under one phone number, and a separate landline connection is no longer necessary. With onephone, your workstations are not only mobile but also smart and individually tailored to your infrastructure. You provide your employees with company smartphones to ensure a strict separation between professional and personal matters.

Do you already have company smartphones?

Perfect, you can continue using them. We upgrade your existing smartphones so that the landline number with extension replaces the previous mobile number. If needed, the mobile number can still be used. Landline phones and two phone numbers become a thing of the past.

Do you need new smartphones?

Then take advantage of our refurbed iPhones as a practical rental option. We have a wide selection of iPhones that have been completely refurbished by our experts. By choosing refurbed devices, you not only show your commitment to your employees but also make an important contribution to sustainability by participating in the circular economy.

Do you want combinational options?

Combine onephone with our softphone clients, and your all-in-one package is complete. This way, your employees are mobile and have all the advantages of a smartphone, such as email, apps, and a camera. In addition, they can make phone calls via VoIP software on their PC or notebook and thanks to a headset have both hands free to work.

The Benefits

One Number Concept

No app, no two devices. No matter where your employees are, they can be reached on the landline number. This increases mobility and flexibility. Home office 2.0.

On the A1 Network

The landline number is natively bound to the mobile phone, no VoIP app required, ensuring no issues with poor data availability and maintaining the same call quality as with a mobile phone.

The receptionist has a full overview: whether someone is making internal or external calls, on the landline or mobile, the status is visible. This automatically increases accessibility.

Central Voicebox

Different announcements on the voicebox are a thing of the past with onephone. A central voicebox ensures a consistent corporate presence, even on the phone.
