Network Validation

By testing your data network’s ability to successfully support IP telephony traffic and discovering potential performance problems before your system is installed, ZAG’s Network Assessment helps you plan, design and implement a successful IP telephony solution.   A Network Assessment is a key step prior to installing a new ShoreTel IP telephony system across multiple sites.

Simulate the voice experience

The assessment uses active application traffic to monitor the live network in order to reveal what’s going to happen when IP telephony is introduced into the mix.

ZAG’s Network Assessment test both Local Area Network (LAN) and Wide Area Network (WAN).  In addition to revealing conditions that could degrade IP telephony performance, the longer assessment helps to identify the source of intermittent problems.   These tests identify or rule out potential sources of latency, jitter, and packet loss issues.  Voice quality is reported in the form of a mean opinion score (MOS), a five-point industry standard scale in which one represents the poorest voice quality and five represents perfect voice quality.

Benefit from specialized expertise

Problems that impact toll-quality voice have many sources including network congestion, geographic distance, configuration, queuing methods used in routers and switches, or routing options used by carriers, such as MPLS or frame relay. Based on a wealth of experience with IP telephony, the test engineer interprets the test results to anticipate dependencies and identify any potential problems. A full report is provided with specific recommendations to maximize the data network’s ability to successfully carry voice traffic.
