Sorry, I've sent last mail without finishing :)
https://kamailio.org/docs/modules/5.5.x/modules/sipdump.html
You only have to load the module and set:
modparam("sipdump", "enable", 1)
Also you can enable or disable using RPC commands:
kamcmd sipdump.enable
kamcmd sipdump.enable 1
kamcmd sipdump.enable 0
Regards
