OK, it stopped working. It turns out the transport and endpoints in PJSIP are ok. I can send an invite from my unregistered snom phone and I can see some activity in the CLI.
However, when I dial from my snom to Kamailio and have it pass the message to asterisk, PJSIP seems to ignore the sip messages even though they are there. Is there something wrong in the invite that I'm missing? U 2015/03/10 22:47:43.539208 [kamailio public ip]:5060 -> [asterisk public ip]:5061 INVITE sip:[email protected];user=phone SIP/2.0.
