PIC conferencing

Question

Sign in to vote

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

It is a known limitation of PIC. See http://support.microsoft.com/kb/897567 for more detail.

There is some discussion of PIC limitations (and a KB article) in this thread:

I know I cannot have more than 2 users in a single IM conversation when connected to any PIC users, and I believe that is a limitation of the PIC infrastructure. Any attempt to add a third, even if from the SAME PIC source (e.g. MSN and MSN), the same error appears:

"Cannot invite Marc Polizzi to join this conference. This person is using a messaging program that does not support more than two participants in a conversation."
