Case Study 2—VoIP Quality Analysis and Assessment

In this case study, we will analyse and assess voice and video quality of the multimedia sessions established in Chap. 8. We will use Wireshark in order to capture and analyse SIP and RTP packet headers. Upon completion of this lab, you will be able to familiarize with Wireshark, tc commands in Linux network emulator, and experience SIP message flows during user registration and multimedia sessions setup and termination. This Lab will also help you to emulate Wide Area Network (WAN) by using tc command in Linux in order to assess the impact of packet loss and jitter on the quality of VoIP calls.
