The paper proposes to clearly elaborate a solution for the understanding of cloud PBX security the future reality of enterprise communication it seeks to clearly underline the different scenarios of implementation of Communication hosted on the cloud in the different unified Communication environments whether Hybrid or complete cloud deployment it also describes the use of different components involved in the planning of Cloud PBX (Private Branch Exchange) hosted by service provider like the use of Active Directory , Database (SQL) , Internet security and Acceleration , Patch Management and certificate deployments to operate the cloud PBX (Private Branch Exchange). The solution itself involves many flavors like the use of Service Integrator certificate normally deployed on client machine to act as mediator for the services operated on the cloud and for software integration of Clients machine to the Hosted Cloud PBX (Private Branch Exchange) , Communication Services Provider (CSP) normally manages the hardware and software integration on their Private Cloud and a Public cloud so that the Core Business is never in the need of any resources or the resources are never less for any shared risk and responsibilities of minimized downtime. The overall cloud deployment reduces client infrastructure manageability and cost at the lowest level with maximum use of resources such as Calling (Voice & Video), Persistent Chat, call admission Control (CAC), Teleconferencing costs also reduce drastically. The large-scale scalability of the solution is nowadays achieved with use of clustering and virtualization of these servers and other tools in the cloud so the effective service operation is maintained at the highest standards.
