About this app

teloFON turns your smartphone into an extension of your company phone system. You make calls using your usual extension, see your colleagues' status, and remain reachable for your team, whether you're at your desk or on the go.

IMPORTANT: teloFON is an application for business customers. You need access from your administrator to use it. The app cannot be used without an activation code and without being connected to a teloFON phone system.

FEATURES

- Answer and make calls via your extension on the company system

- Incoming calls in full screen, showing the caller's name and extension

- Contacts from the company directory and personal call list

- Team overview: see which colleagues are free or on a call

- Pick up calls from colleagues
- Hold, transfer, and key tones during a call

- Bluetooth headset, speakerphone, and handset

- Do Not Disturb when you want to be temporarily unavailable

- Log in with multiple devices simultaneously

HOW TO SET UP teloFON

Your administrator will create your extension and provide you with an activation code. You enter this code once in the app. After that, your smartphone is connected to the company system, and you can be reached at your usual extension number.

WHY teloFON USES A FOREFRONT SERVICE

As soon as you answer or start a call, teloFON uses a foreground service. This keeps your call active while you leave the app and continue working in another application. The ongoing call is always indicated by the notification; it disappears as soon as you hang up. This service is not active outside of a call.

Microphone access is required for voice transmission during calls. Incoming calls are delivered via an encrypted push notification.

REQUIREMENTS

- Android 7.0 or later
- Access to a teloFON telephone system
- Activation code from your administrator
- Internet connection via Wi-Fi or mobile network

teloFON is a product of teloNova FlexCo.

What’s new

Angemeldet bleiben: Nach einem Neustart des Handys zeigte teloFON kurz die Aktivierungsseite und wirkte abgemeldet. Die App wartet jetzt, bis die gespeicherten Zugangsdaten lesbar sind.

Abmelden wirkt sofort: Beim Abmelden wird die Anruf-Benachrichtigung dieser Nebenstelle auch am Server abgemeldet. Das Gerät klingelt danach nicht mehr bei Anrufen an die verlassene Nebenstelle.
