Howdy! I am bringing up my first v15 server. We are using Fusion Connect as our trunk provider. I have other v14 servers also using Fusion. on the v15 server, the firewall check passes. We are using a SonicWALL NSA 220 with current firmware which includes the hotfix. Looking at the turn up letter, I don't have a username/password so I assume I am using the IP Based Registration. Looking at my external IP (checkup.dyndns.org) it is the IP address that Fusion has on the turn up letter. I don't have any extension configured, but when I test an incoming call my cel hangs up. Running a wireshark on the PBX, with a filter or RTP, I don't see any traffic. Any idea how I can tell if the v15 server is registering or if the issue is at Fusion? Thanks!
