That the phone application is launched does not mean the user is currently in a call, they could be browsing their contacts list.

Skype is an even worse example too, I use it for IM more than calls and it presumably stays open for a long time, probably forever on those occasions.

Skype wants to BE your phone app. It is not allowed.
