A first easy hint would be to go out there and get yourself a nice copy of ngrep, "ngrep -d eth0 port 5060 -W byline -q " will help you understand the magic of SIP much easier.

I think you could get yourself upto speed by trying to get one of the many example configuration files to work. 

I believe there also is a book on Opensips, which is a great help to get you started.

... and enjoy the learning curve :) !

Additional info I failed to add:
OS is Ubuntu 14.04 server(Trusty tahr)
OpenSips 4.x installed and running with MySQL module
have an old polycom 501 that is hitting the Kamailio box with register
requests as seen by tcpdump:
09:59:28.921267 IP 192.168.1.110.sip > 192.168.1.152.sip: SIP, length: 530
09:59:28.921663 IP 192.168.1.152.sip > 192.168.1.110.sip: SIP, length: 448
