XChange Voice by Marlink is a telephony service app designed for Android devices. With this app, you can turn your Android device into a local phone for voice and VoIP telephony services provided by XChange.

One of the main highlights of XChange Voice is its simplified registration process. You only need to register once with your XChange user account, making it convenient and hassle-free. The app also boasts a simplified layout and an intuitive user interface, ensuring ease of use for all users.

Another noteworthy feature of XChange Voice is the direct dialing capability. You can make calls to both internal and external numbers directly from your "Contacts" or "Favorites" list. This makes calling your contacts as simple as using a regular cellular phone.
