    Exporting SIP signalling to text

    ss_daveh New Member

      I found this helpful post: https://supportforums.adtran.com/message/2248 and was able to set a packet dump in hex format and import to Wireshark PCAP. However, I am having difficulty getting SIP signalling to be exported in hex format and importing to a PCAP in a format that actually shows sip messaging. Does anybody have experience setting this up?

          Hi ss_daveh:

           

          I like to create an ACL to define what I want to debug/dump in the console.  Example:

           

          ip access-list extended sip-capture

            remark sip-capture

            permit udp any any eq 5060

           

          Start logging to a text file in your terminal application, then use the following command at the enable prompt to begin the packet dump:

           

          debug ip packet sip-capture dump

           

          When finished:

           

          undebug all (or just u a)

           

          Stop your text logging and then follow the instructions in the post you mentioned to convert the text log to a PCAP file.

           

          Sometimes it's important to collect data over a long period, but SSH/telnet sessions typically timeout after a few minutes.  I found this article helpful to setup persistent debugging over a longer period:  Enabling Persistent Debug Logging

           

          Good luck,
