What information is provided by the VoIP option in Protocol Expert?

VoIP is a software option to OPV-PE that analyzes multimedia traffic over Ethernet-based networks. VoIP validates Quality of Service (QoS) parameters presented by PSTN/IP Gateways, IP switches, and IPBXs. VoIP provides a rich set of reported and calculated data to validate IP networks that carry the multimedia data. The transmission of voice and video over traditional "data-only" networks is one of the most active areas in today's telecommunications industry. Voice over IP (VoIP) refers to the transmission of voice that has been compressed and transmitted over an IP (Internet Protocol) network. H.323, SIP, SDP, MGCP, and SCCP are key industry standards that enable VoIP communication. These standards address call control, multimedia management, bandwidth management, and interfaces between LANs and other networks.   Given the rapid acceptance of IP as the de facto protocol, QoS has become one of the biggest challenges for network administrators, especially for voice and video applications that require real-time performance. Policy-based systems, gateways, switches, and routers are often configured with a myriad of vendor and protocol combinations to work in unison to provide re of IP, the measurement of the actual call traffic is an essential tool to ensuring Network QoS. VoIP provides a distributed solution to measure the QoS of all the existing calls without having to generate a specific "test call". Measuring real calls eliminates the need to add test traffic to the network, doesn't limit the solution to spot checks, and enables the solving of "real-world" call problems in a deployed environment.   Full decode of multimedia protocols by VoIP provides users with the ability to look at any captured packet and understand its contents. VoIP validates that the network is performing as it has been configured and helps you troubleshoot problems.  VoIP provides graphic summaries of Call Jitter, Dropped Packets, and Call Set-up Time to view network performance at-a-glance. Point-and-click on graphs to see call tables. Click on any call to get complete call details. VoIP features are only available from OPV-PE menus and toolbars when you have the VoIP option.
