For most organizations today, it’s less a matter of if
and when, but more, a matter of how to embrace
IP telephony communications. Since 2005, when
the balance tipped and more IP telephony systems
were shipped than traditional time-division multi-
plexed (TDM) phone systems, Voice over IP (VoIP)
has become the technology of the present and the
future. In thousands of installations worldwide, VoIP
communications are daily enhancing collaboration,
increasing productivity and lowering costs. But even
networks that have been optimized to handle large
and complex data workloads may not be ready for
an IP telephony implementation.
WHAT CHARACTERIZES A VOICE READY NETWORK
QUALITY. Delivery of reliable, high-quality voice communi-
cations—comparable to what users get with traditional
PBX systems—plus, support for advanced IP functionality.
SECURITY. Protection of voice traffic from vulnerabilities
and threats, including those introduced by data traffic run-
ning on the same network infrastructure.
SIMPLICITY. Elimination of complexity for users and man-
agers, and the ability to easily and economically scale the
network to support new devices and applications.
To carry on business effectively, users must be able to conduct conver-
sations as if they were in the same room with the person on the other
end of the line. With the latest codecs, audio quality on IP phones now
surpasses what was previously possible on analog or even non-IP digital
phones. But to attain business-level clarity and immediacy, the network
must deliver sufficient bandwidth to support the voice traffic and pro-
vide the quality of service prioritization that prevents latency, “jitter”
and prolonged call setups.
Just as important, the network must be able to reliably deliver a dial tone
across the entire organization, over both wired and wireless installations.
Phone users have long been accustomed to virtually 100% uptime. Many
businesses cannot tolerate interruptions in their telephony service, losing
