I am using Asterisk SVN-branch-1.4-r75450M with videosupport=yes. The incoming INVITE does not include video in the SDP. Also the 200 OK from Asterisk does not include video in the SDP. Asterisk opens 4 new UDP ports which will be opened for the whole call duration. Is there a method to find out if the 2 additional ports are really the video RT(C)P ports or if they belong to something else? regards klaus _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-dev mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-dev
