Hi! To understand what is happening, you should analyse SIP exchange, use for example: ngrep -d any -qt -W byline "sip" port 5060
you can also use tcpdump with following studying in wireshark. To find out what part of kamailio's configs SIP message processing passed, add logs, and analyse syslog output, while dialling. To get understanding how kamailio works - you have to understand how works SIP, there is no other ways.
