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.
