Set Capture Filter
Set Display Filter
• SIPv6 Analyzer provides two Filters: Capture Filter and Display Filter.
• The filter rule is the same as the tcpdump. • Some useful examples:
– host 140.113.1.1 (capture the packet from and to 140.113.1.1)
– dst 140.113.1.1 / src 140.113.1.1 (to/from 140.113.1.1) – net 205.153.60.0 mask 255.255.255.0 (for a subnet) – udp port 5060 (for SIP; port 9000 for RTP) – host 140.113.1.1 and udp port 5060 – ip6 (for IPv6 packets)

ConclusionsConclusions • SIPv6 Analyzer provides several functions (e.g., SIP Viewer
and RTP Spy) for the users who attempt to debug the SIP VoIP network or the SIP devices.
• SIPv6 Analyzer can be downloaded in the web page (i.e. http://www.csie.nctu.edu.tw/~yhsung/sipv6_analyzer)
• Users can fills the registration form and will be informed when the SIPv6 Analyzer is upgraded.
• Users can contact Dr. Chen ([email protected]) for any further research or cooperation possibility.
• Users can contact Mr. Sung ([email protected]) for the comments or bugs of SIPv6 Analyzer.
