The citron protocol does not work well when tunneling is disabled. Try to enable H.245 tunneling. You will not only get rid of problem, but get a better performance/faster audio setup time. ----- Original Message ----- From: "张玉业" <yuye@xxxxxxxx> Sent: Friday, November 26, 2004 4:19 AM > Sorry for my poor English.
