Cisco TelePresence Content Server 4.1 printable online
Page 113 of 121
Note: The Windows Media player will automatically use protocol rollover if necessary. The default
streaming protocol for the Windows Media player is RTSP on port 554. If the player cannot obtain the
stream using RTSP (because the port is blocked on a firewall, for example), then it will automatically
rollover to MMS. MMS (port 1755) is a deprecated streaming protocol and is not used as a streaming
transport for Windows Media Player version 9 and above. The player will then try HTTP on port 80.
