Quality Scoring Observer displays the individual Mean Opinion Score (MOS) and R-factor for every call and as an average for all calls. Quality scoring is conducted using the ITU E-Model. During VoIP Setup, you may customize the impairment factors of the E-model depending on your VoIP equipment and network characteristics. For example, VoIP quality on calls made from the factory floor over multiple hops may be scored differently to calls made within a small office setting. VoIP

VoWLAN With the Network Instruments Distributed Network Analysis (NI-DNA) architecture, all of Observers VoIP enhancements are automatically available across multiple topologies. For example, Observers VoIP Expert has the capability to monitor VoIP traffic even over wireless networks. Jitter Observers VoIP Expert displays the statistical variance of packet arrival times, also known as jitter, measured in timestamp units or RTP time units. VoIP Decodes Observer offers complete decode of voice and video protocols, including H.323, Session Initiation Protocol (SIP), MGCP, and SCCP (Cisco "skinny"). VoIP Conversation Graphs The VoIP Expert displays H.323/SIP conversational data in three separate graphs. Each display is designed to help identify why a connection may be experiencing problems, or at what level of network load are H.323 conversations exhibiting acceptable quality behavior. Displays include jitter and lost packets (%) for each direction of the conversation, total RTP/RTCP bandwidth utilization, total utilization and each conversation's percentage of total utilization.
