Hi,
Thanks you for your reply.
Found it myself yesterday... i was going to post the solution today.
enable=no in the notification section of "/usr/share/yate/skins/default/qt4client.rc" will do the trick.
To bad i couldn't fix the focus stealing.
Somehow i believe it's not going to work solely by modifying the qwidget's properties in notification.ui.
Otherwise is the best and stable SIP client i've been using since twinkle.
Thank you,
