Voice communication continues to play a defining role wherever work depends on coordination, authority and continuity. Enterprise telephony provides the structure that allows calls to follow known paths, responsibilities to remain visible and communication to stay dependable under pressure. This book explains how EPABX, IP-PBX and unified communication systems are designed, deployed and sustained in such environments.
The discussion builds from core principles such as numbering, routing and trunking, and moves into integration, governance and service responsibility. Technical ideas are presented in a way that supports learning without assuming prior specialisation. Field based cases show how organisations introduce IP and cloud technologies while retaining stable voice foundations.
Regulatory expectations, infrastructure constraints and operational support are treated as part of system design. The book functions both as a working reference for professionals and as a structured academic resource for readers seeking to understand enterprise telephony in practice.

Dr.Huzaifa Y.Biviji
Dr. Huzaifa Y. Biviji is a telecom and automation professional with over three decades of experience in enterprise communication and building systems, since 1990.
His work spans EPABX and IP-based telephony, CCTV, access and attendance systems, fire alarm systems, public address systems, AV solutions and boardroom automation. Over the years, he has delivered more than 1,000 projects across hospitality, commercial offices, campuses and industrial facilities.
One of his early contributions was the SPAM (Save Power And Money) system, developed to reduce energy consumption in hotel operations. This marked a broader focus on improving efficiency through thoughtful automation rather than isolated technology upgrades.
Huzaifa’s approach begins with close study of operational pain points such as fragmented communication, rising energy costs and unreliable infrastructure. Solutions are designed at system level, covering signalling, power, cabling, integration and long-term support.
Clients value his focus on stability, accountability and practical execution rather than surface features. This book reflects his field-led perspective on how telephony and automation systems are planned, implemented and sustained in real environments.
