I'm trying to get Live Messenger's extended features to work. Chat works fine. When I try to phone, it rings at both ends, but when the correspondent answers, there's nothing. Similarly, the correspondent sees the shared folder, but no files. We've tried phoning from both ends, and each has shared a file or two, but still nothing. In the ZA Control Panel, "IM Security" is at Medium, and all functions have a green tick except for "Inbound Active". Messenger has the 3-stripe green "super" classification in Program Control, and all "Access, Server, and Email" boxes have green ticks. It's probably something simple, but I can't find it. Suggestions would be much appreciated!!!
