An integrated web based unified telecommunication solution on an n-tier server architecture.

Telecommunications technology is ever evolving to meet the rapid changing needs for services in organizations. Private Automated Branch Exchange/Private Branch Exchange (PABX/PBX) is a telephony platform that is privately based and links between a subscriber and a telephone network which is switched in nature. The functional technology applied is a Public Switched Telephone Network that allows the shared application of connectivity between departments in an organization. Consequently, the technology incorporated other components, e.g. ADSL lines to establish an extension which was not linked to the numbering plan of the central point and the number block associated to the PABX/PBX. Although it was a renowned state-of the art technology for handling communications within organizations, it developed challenges which led to its inability to meet organizational telecommunication needs, for example, technological challenges, limited monetary resource and loss of communication connectivity due to scalability and vandalism. In this research project, an implementation of an integrated web based unified telecommunication solution on N-Tier Server architecture was adopted. There are other solutions which have been applied to address the issues, but there are a number of areas that have not been tackled e.g. security because in the event that the platform is managed by a third party, its level of security standard is not guaranteed. Also loss of communication connectivity and cost of implementation have not been adequately addressed. The solution uses existing infrastructure equipment like servers which will be virtual to form a front end and back end server linked together to achieve its function.
