How It Works
Gama Infotech’s Multi-Tenant PBX System operates on a robust cloud-based shared infrastructure, enabling multiple organizations to run their communication systems on a single platform while maintaining complete privacy and separation. Each tenant is provided with an independent and secure environment where all call data, configurations, and user activities remain fully isolated.
Service providers and resellers can efficiently control and monitor the entire system through a centralized management panel. This allows easy allocation of resources, customization of features, and management of user roles, extensions, and permissions for each individual client — all from one place.
The platform supports multiple business domains within a single application, making it ideal for managing diverse clients under one system. Incoming calls are intelligently routed to the appropriate extensions across IP phones, softphones, or mobile devices, ensuring seamless connectivity.
With Gama Infotech’s integrated mobile and web applications, users gain complete flexibility to communicate from anywhere. The system supports voice calls, video communication, instant messaging, and team collaboration tools, enabling smooth internal and external communication.
Additionally, smart call handling features such as call forwarding, failover routing, and availability-based call transfer ensure that no business call goes unanswered. Whether users are in the office or on the move, they can always stay connected using their official business number.
