This application, called Zoiper, allows users to make and receive calls and send and receive messages through their office PBX or voip service provider. It serves as a default dialer for these services and offers various features such as video calls, conference calls, call waiting, call transfer, and chat. It also supports multiple accounts and provides encryption for secure communication. However, it is important to note that this version of Zoiper is not suitable for use in a production environment as it may crash or lack important features. In-app purchases for additional features are also disabled. If the application continues to ring on your device, you can use the "Force Stop" option in your Android settings to stop it. If you encounter any bugs while using Zoiper, you can send a report to the developers at [email protected]. They encourage users to be original and SEO-oriented in their reports. This allows them to improve the application and provide a better user experience. Overall, Zoiper is a useful tool for managing calls and messages through your office PBX or voip service provider, but it is important to use it with caution and report any issues for future improvements.
