This same issue goes for phone calls as well. With the new continuity features for Mac, it allows you to use your iPhone to make calls from your Mac. I can change the setting within FaceTime to make my iPhone the default for new audio calls, but every time Jabber loads, it hijacks the default. When clicking on a phone number on a webpage or in my contacts, I would like it to use my iPhone, but every time Jabber is restarted, it resets itself to the default.
