Title: Feature dialer speaker bug 4382

There was some desynchronization regarding the speaker button between calls. Now they are synchronized, this means that the speaker status is kept between calls (if you make a call and set the speaker on, it will be on on the next call). This is the current behavior. I am going to check with UX that this is the desired one ;-) or maybe the speaker status should be set to off on every new call ;-)
