While dealing with Cisco Meeting Server (CMS), you may encounter many errors such as audio / video packet loss, signaling problems, and you may need to listen to network traffic from time to time to fix them. In this article, you can find steps to get Wireshark Packet Capture in Cisco Meeting Server (CMS).
