Abstract:
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 virtualized to form
a front end and back end server linked together to achieve its function.
