I have also signed up for a new Jabber account and I have the same issues when trying to establish a video call with both Jabber and EX90s. FYI I am using the OSX 4.4 version. My screen shows no video and then no audio. When I check the information screen It shows I am sending data but not receiving anything. I have checked my Internet router and can see that I am sending data @ ~ 1.5mbs but I am not receiving a data stream from the party I am trying to call. I have gone as far as putting my Macbook on a DMZ for testing on the public Internet to ensure there were no firewall issues with ports being blocked. After seeing this thread I am wondering if there is something wrong with how Jabber free is being centrally managed or provisioned. Can someone who is managing the free Jabber enviroment please look into this issue.
