Hi, I read in the Debian Skype wiki that you can't do calls on Web Skype, but I just tried it in Jessie and it worked, for a conference call (no video though). I think it only works in Chromium (I tried with Firefox too, but some time ago). It would be useful to add that information to the wiki, so people know they don't have to install the alpha version of Skype for Linux. Best regards, Paulo Almeida
