Enable debug and log files

The debug flag may be enabled to produce more detailed output. The following .sipvicious.toml configuration (stored in the current working directory) would enable debug logs and log the output to a file:

logfile = "sipvicious6.log"

  logging = true

The same effect can be achieved by making use of the following flags: --logfile sipvicious6.log --debug.

Produce packet captures

Make use of Wireshark, tcpdump or a similar tool to capture the traffic that SIPVicious PRO is producing so that we can reproduce the issue. Make use of a network capture filter such as host where is your target machine.

Make use of TLS key log

If using SIP over TLS, it is helpful to be able to decrypt the TLS traffic when sending packet capture files to us for analysis. Make use of the tls-key-log and send us the output file together with your packet capture files.

Troubleshooting templates

If the issue is with a custom SIP template, please make use of the sip utils template test tool for debugging purposes.
