VOIP & TEAMS TELEPHONY

Modern communication – flexible, secure, and remote-ready.

CloudCall and our Microsoft Teams integration enable reliable, cost-effective, and scalable business communication. Both systems can be operated as classic on-premises solutions, cloud-based services, or combined in hybrid scenarios – ideal for companies that want to use VoIP devices and Microsoft Teams in parallel.

Operated in our Swiss data centers, exaSys ensures the highest availability, Swiss data security, and a solution that grows with your business.

Whether modernizing existing phone systems, connecting multiple locations, or running CloudCall and Teams in a hybrid setup, we ensure your communication remains stable, secure, and seamlessly integrated.
