Hi, I'm trying to connect the PJSUA sample app to a public asterisk box. I am behind a cisco PIX firewall. I can make outbound calls fine, but on all inbound calls, asterisk thinks that my line is busy. I am receiving NOTIFY packets from asterisk, however I see the following message a lot in the console output: 11:09:02.156 sip_endpoint.c Message Request msg NOTIFY/cseq=102 (rdata00BE5EAC) from 64.209.211.3:5060 was dropped/unhandled by any modules So it seems as though the app isn't responding to NOTIFY messages, so asterisk thinks I am offline. Is there a way to fix this? Thanks. -- James
