Voice over IP call quality and reporting gained another helping
hand with the recent partnership between Texas Instruments and
Network Physics.
Developed to deliver optimised end-user experiences for VoIP and
IPTV services, the partnership, by utilising Texas Instruments'
PIQUA quality management system, will improve enterprise IT
managers' and service providers' real-time visibility into
VoIP call performance problems. It will also provide automated
corrective actions that will help alleviate some of the challenges
faced in delivering IP-based services.
"Self-correcting abilities, such as those found in PIQUA and in
Network Physics' NetSensory solution, play very important roles in
the strategy to improve call quality," said Scott Safe, vice
president of marketing and product management at Network
Physics.
Utilising real-time calculations to assess quality parameters
related to the user's experiences, Texas Instruments' PIQUA system
is based on its digital signal processor (DSP) technology and
embedded software solutions. This system allows both equipment
manufacturers and service providers to automatically respond to
changing conditions on the network and make the necessary
adjustments.
By integrating Network Physics' NetSensory Solution Insight for
VoIP 2.0 with Texas Instruments' PIQUA system, the partnership can
improve call quality before the end user detects a performance
problem.

Deploying VoIP: Five things every CIO should know
Navigating the complexity of a VoIP deployment can be overwhelming
and it may seem like you need a technical degree to understand it.

This integration between softwares is achieved by using standard
protocols such as RTCP-XR to communicate call quality metrics and
RTCP-XR extensions to report echo quality metrics these softwares
integrate to improve the overall end-user experience.
"Working with Network Physics, our PIQUA system automates the
process of gathering IP endpoint performance metrics and converts
this data into real-time actionable information, improving the
delivery of IP services," said Debbie Greenstreet, director of
service provider strategic marketing for Texas Instruments. "The
results of our alliance will include improved user experience and a
reduction in overall network operating costs."
Combining the information it gathers from the endpoint and
correlating it with the other network data, Network Physics'
NetSensory tool provides network operators and enterprise IT
managers with a set of metrics that allows for a faster resolution
of performance issues during a VoIP call. This also reduces the
need for additional equipment testing -- freeing the IT staff from
having to hunt down the cause of the performance problems.
Network Physics said the NetSensory solution is designed to
alleviate problems that are associated with voice-monitoring
solutions by integrating standard voice-quality metrics with more
than 60 performance and utilisation metrics -- allowing for the
delivery of real-time management of both voice and data
applications.
Moreover, drilling down from voice-quality metrics to the
underlying network conditions responsible for call degradation,
measuring the impact of other enterprise applications, and judging
how other applications are affected by the network changes are the
factors that will improve voice quality, according to Network
Physics.
"The whole point of deploying VoIP is to run voice across the
network just like any other application," Network Physics president
and CEO Kenny Frerichs said. "The marrying of TI's PIQUA technology
and the NetSensory Solution Insight for VoIP seizes the full
advantage of the PIQUA system by creating a solution that optimises
services based on true end-user experiences and provides
exceptional insight into application performance."
