About this app

CallBox, professional telephony designed for teams.

Access your company's telephony on your Android smartphone: make and receive business calls, see in real time who is available on your team, view the shared call history, and organize conferences, all from a single app.

CallBox uses an account provided by your company. Your login details will be given to you by your administrator or your phone provider.

MONITORE YOUR TEAM IN REAL TIME

The monitoring screen dynamically displays the status of each of your team members. This allows you to quickly identify who is available to take a call and direct callers to the right person.

Organize the display of your team members with simple drag and drop.

A SHARED CALL HISTORY

The shared call history for your group gives you a complete overview of the team's phone activity, including calls answered by a colleague.

You know instantly if a call has already been answered: no more unnecessary callbacks or duplicate calls.

YOUR BUSINESS CALLS, ANYWHERE

- Receive calls even when the app is closed, thanks to notifications.

- Stay reachable at the office, while working remotely, or on the go.

- Use CallBox over Wi-Fi or 4G/5G. Your business line follows you, without depending on your landline.

HOLD CONFERENCE CALLS

Bring multiple participants together in a single conversation and transform a one-on-one call into a group discussion in seconds, directly from the app.

A SOFTPHONE DESIGNED FOR BUSINESS

CallBox is a VoIP (SIP) softphone that connects to your company's phone system. Calls, monitoring, shared call history, and conferences are all integrated into an app designed for business use.

Your business phone system.

Your team.
