Mobile UCaaS

The native integration of the Communi5 Voice Application Server (VAS) into the core network of a mobile network operator (MNO) takes voice services to a new level and transforms mobile devices into full extensions of the corporate telephone system. Users have access to important PBX functions such as call forwarding, voicemail, call recording, conferencing, and IVR directly on their mobile phones.

Employees remain reachable under a single business number, ensuring seamless communication whether in the office or on the move.
The key advantage of this integration is the use of the native mobile phone dialer without the need of any additional app on the mobile phone.

Another real benefit is the real-time availability status (“busy lamp”) of mobile users, which can now be integrated into corporate call routing. This means that if a mobile user is on a call, their status is recognized within the company PBX, allowing intelligent routing decisions such as redirecting incoming calls to colleagues or voicemail. This prevents unnecessary interruptions, improves call handling efficiency, and ensures a smoother customer experience.

For Mobile Operators, this integration strengthens their business service offerings by providing enterprise customers with advanced unified communications and seamless PBX integration. The NNI interface allows for quick deployment with minimal infrastructure changes. The multi-tenant capability of the Communi5 VAS enables multiple businesses to utilize the same platform, reducing operational costs while supporting scalability.
