Network Management Protocols In International Telephone Calls: A Review

Abstract

From contemporary knowledge international telephone service is a
special brand of subscriber facility. At any point in time the telephone
industry casts reflections on the history of the system for objective
planning purposes. This study examined the current State-of-the-art
in respect of initiating and completing an international telephone call
from any point under the sun. The literature on international telephone
communication described the telephone development in relation to
the technology that supports the transformation of the system in modern
times. The study was adapted from the congestion theory that explains
the processes that lead to telephone traffic exigencies. This theoretical
frame of thought facilitated the understanding of the processes through
which voice signal transverses from its focused analysis of the hurdles
through which international telephone business operates. From those
objective analyses it was found that the international telephone
message signaling systems are highly regulated to protect the interest
of stakeholders.
