MORE INFORMATION
When you use audio and video in a Live Meeting 2007 session, Live Meeting 2007 uses one of the following methods:
• Live Meeting 2007 uses a direct connection to a media relay.
• Live Meeting 2007 uses the proxy settings that are configured in Windows Internet Explorer to connect through an HTTP proxy connection.
The following two protocols are used for audio and for video in Live Meeting 2007: • User Datagram Protocol (UDP) port 3478
• Transmission Control Protocol (TCP) port 443
Typically, UDP is preferred for performance. However, UDP connections can cause network congestion. Audio and video use TCP if UDP ports are blocked. TCP lowers network congestion. However, TCP also lowers the quality of audio and of video. Audio is affected the most when TCP is used because the ear is more sensitive to disturbances. When you use TCP, audio and video are encrypted by using Secure-RTP. To decrypt the audio and video media, Session Initiation Protocol (SIP) signaling is performed through SSL port 443.
When you connect to Live Meeting Manager, SSL port 443 is used. This is a Web site where meetings can be scheduled and updated over the Internet.
To enable users to watch streaming recordings of a video or to hear streaming recordings of audio, the following range of streaming ports is used:
• TCP ports 80, 443, 554, 1755, 7070
• UDP ports 1755 and 5055
If these ports are not opened, users can still download a recording over SSL port 443.
