No firewall - though of that too at first. There is a PIX between the net and the servers, but not between the Opensips server and the Asterisk server. The packet capture showing the modifications to the INVITES was from the Opensips server - in-n-out. No firewall involved at that point. The Opensips server is 67.212.153.178 and it's forwarding to the Asterisk server which is at 67.212.153.179. Due to previous issues with the sip fixup in PIX firewalls, that it disabled in the PIX we're using. But again, this modification is being done after the PIX hands it off to the Opensips server....
