Voice over Internet Protocol (VoIP) is changing the rules on how we monitor, analyze and troubleshoot our networks. Unless all of your VoIP users are sitting in your data center, the only way to truly understand call quality and network performance requires you to have visibility into all your VoIP traffic—at both ends of the conversation!

VoIP, like wireless, often requires “point-of-presence” troubleshooting to see exactly what the user is experiencing. Unlike traditional data protocols, VoIP is sensitive to delays, network congestion, and jitter as it traverses your network. Network packets that pass through the core without a problem may present a totally different story by the time they reach the remote office.

This white paper examines the various factors that can lead to poor VoIP call quality (including additional information on special considerations for voice over wireless) and how a network administrator can use WildPackets® OmniPeek™ Enterprise to pinpoint issues and keep the VoIP network running smoothly and efficiently.
