Software Solution

Axmor developed a mobile unified communications application. Employees have access to all the basic functionality of the unified communications system. To access the mobile application, the user needs an account in the system.The application has a remarkably easy-to-use call control, a user-friendly interface, and high rates of data transmission and processing. It requires no further configuration and is ready to use immediately after login. The corporate identity was taken into account, when developing a mobile application.

Voice calls

The user interface supports voice calling over the Internet (VoIP). With this application, an active call can be rerouted to another employee, a call can be put on hold or transferred, and the user can keep talking using another device (switching from a mobile phone to an IP phone and vice versa without disrupting the conversation). Another person can be invited to the conversation, or the call can be continued as a conference call. Also, other features of mobile application can be used during a call and several calls can be taken at a time. Any call can be recorded and saved on the server.
