VOIP Solutions Architecture
from:Author: Hope Ocampo
Voice service is critical to the operation of the business, so
no one wants to implement a technology that will compromise call
quality or reliability in any way. Thus, the selection of an
enterprise VoIP solutions Architecture is a major decision.
On the other hand, the cost savings and value-added
functionality available with VoIP makes it a compelling
investment. So VoIP buyers must select a VoIP Solutions
Architecture that maximizes business benefits while minimizing
potential technology ownership headaches. The design of IP voice
solutions should address the following service-level
requirements: Open and standards-based VoIP solutions
architecture : Enable the IP voice solutions with the
flexibility of a comprehensive solution portfolio that
interoperates with existing TDM technologies and systems, while
protecting existing investment.

solutions architecture : Enable the IP voice solutions with the

Extensibility : The VoIP solutions Architecture should have the
ability to have additional functionality added or to modify
existing functionality without impacting the existing
functionality.
Scalability : The VoIP solutions architecture will provide the
ability to quickly and easily extend the network infrastructure
and application to handle increased contact loads or much more
agents or new components and applications.
Reusability : Addresses the ease with any functional components
or concepts within the VoIP solutions architecture can be reused
by other applications.
Maintainability : The VoIP solutions architecture should have
the ability to deal with technical issues in existing
functionality without impacting other subsystem or components of
the VoIP voice environment.
Performance : The VoIP solutions architecture should have good
performance across all solutions. For example, good Quality of
Service (QoS) mechanisms ensure high voice quality through tight
control of delay, loss, and jitter.
Manageability : The VoIP solutions Architecture must be easy to
be used and managed by most the administrator and technical
staff. Also, choose good network management products to provide
network administration, operations, troubleshooting,
configuring, fault monitoring, and element management.
Additional difficulty in making a purchase decision is the broad
range of vendor offering VoIP solutions Architecture on the
market.
These offerings can be segmented into two categories: low-end
VoIP gateways and high-end router-based solutions.
Low-end gateways VoIP solutions Architecture is tempting
because of their low upfront cost. However, they lack many
important capabilities that are essential for VoIP to work as
required in real-world network environments and to fulfill the
requirements of the business. Their poor survivability, lack of
intelligent call routing functions and inadequate integration
with existing enterprise communications resources limit their
usefulness and can lead to problems in provisioning VoIP
services as required.
High-end router-based VoIP solutions Architecture
products come with a larger price tag and, at first glance,
offer more sophisticated VoIP functionality. Unfortunately, they
often come with further price premiums in the form of PBX
modification and add-on modules for support of H.323 and/or SIP.
And, despite their price and apparent robustness, their
capabilities may still come up short in many ways - forcing
users to change their dialing habits, limiting the efficiency
with which available bandwidth can be used, and exhibiting the
same lack of survivability as their low-end counterparts.
