  • Microsoft Live Meeting
    • Microsoft Office Live Meeting uses TCP/TLS ports that are in the range of 8000 to 8100.  If Live Meeting is unable to connect to ports that are in this range, Live Meeting uses the standard HTTPS port 443, if this port is available and if not falls back to a port 80 HTTP request to make a Console connection.
    • Live Meeting uses http port 80 to negotiate Internet Audio Broadcasting (IAB) connections
    • Live Meeting uses TCP/UDP port 554 for Real-Time Streaming Protocol (RTSP) connections
    • Live Meeting uses TCP/UPD port 1755 for Microsoft Media Services (MMS) connections
