Automated attendant works fine, no problems. Every thing else works, but when the system forwards to Voicemail it goes silent, and just holds the line open until you hang up. Happens with any type of call, and there is no Firewall setup at this time, so all traffic can flow freely. It is a Windows 2003 box, nothing else running.
