About this APK

3CX is an app by 3CX in the Communication category, listed since at least July 2021. It includes native code only for ARM (legacy), so it won't run on 64-bit-only phones such as recent Pixels.

Since version 15.5.346, the minimum Android version rose from 4.1 to 5.0. It asks for 29 permissions, 10 of them sensitive, including camera, record audio and read contacts. Compared with version 15.5.346, it adds 3 new permissions (“Approximate location”, “Manage own calls” and “Write sync settings”) and drops 2 (“Read logs” and “Write settings”).

What's new in v16.0.0

Fixed a crash that would occur while in the "Conference" screen. Fixed a crash that occurred when creating a group chat with a specific type of user. Fixed a crash that would rarely occur when importing a .3cxconfig file into the 3CX app from a ‘3rd party application. More fixes and improvements

Description

From the listing uploaded by “appupdater”.

The 3CX client for Android requires 3CX PBX Server v15 and will not work with older versions. Do not download or rate if you do not have an installation of 3CX Phone System. This app allows you to make and receive office calls on your Android device from anywhere. The app fully supports PUSH, allowing your device to be on standby when not in use and save battery life. When an incoming call occurs on your office extension, your device will 'wake up' and notify you as it would with a regular GSM call. Benefits include: - Make and receive calls on your smartphone/tablet from your office extension. - One number concept - Calls made to your office extension will ring on your Android device. - Reduced mobile phone bill; call colleagues via the 3CX app rather than via the mobile network. - Seamless out of office or in office detection. - Transfer & Hold calls. - Easily change your status (available, busy etc.). - Receive multiple calls simultaneously. - View the status of your colleagues. - Easily setup conference calls. - Instant Corporate Chat. The 3CX Android client requires Google Push to be configured by your organization's PBX administrator.
