VoLTE for Unified Communication


Enterprise mobility and flexibility is increasing. Modern workforce users are becoming more mobile and more collaborative but enabling collaboration from native dialer is not easy. The current typical end user mobile experience is that there are no Unified Communication features accessible from native dialer, there is no quality of service, the calls through the OTTs are a best effort service through open internet and the calls are unstable. This is unproductive in today’s market.

Since business users work from different locations, they need to collaborate from any of their devices including from the mobile devices and reachable through different personas and still have access to their enterprise features (presence status, name presentation, hunt groups) and their collaboration environment. The business users would like to have a stable voice connection and be able to share content, start a video call or conference and have common document handling. They want to have the same collaboration environment available on all their devices.
