Is it possible to IM conference with Yahoo, MSN or AOL ffrom Communicator. So far I have Yahoo and AOL working for IM and when I try to confernece with either, I get an error stating that the messaging program can not support more than two participants in a conversation.
Should I take that for what it means or might I need more config, possibly on the firewall. Currently I only have port 5061 open.
Thanks
