Is there a VoIP tutorial or sample setup for VoIP? I sell VoIP IP PBXs and would like to use Astaro. To date I have not had success with the VoIP proxy or QOS. I typically have a IP PBX inside the firewall. I can get the VoIP security to work but then my remote phones do not work. Also not having much success with QOS. Can someone point me in the right direction. Searching the forums has not been much help on the remote phone issue.
