I have noticed the same thing. I have the sense that this is mainly due to
the automatic gain control for both the microphone and speaker that is built
into the VOIP application. When you turn the main volume up, it decreases
the internal speaker volume to avoid echo to the caller. So you end up
fighting it. This definitely needs to be tweaked a bit. It seems to do the
same thing on the mic too. If you make a sharp noise like a clap or tapping
the 770 case, it takes quite a long time for your caller to hear you again
as the VOIP app readjusts your mic capture gain back up.
