Handle conference and on hold music.

Browse source 
When hosting a conference, mute conference participant when he
pauses us to prevent his holding music to be played to all participants.

When resuming a call, stop immediately sending the hold music,
even before receiving the 200OK. When the paused call is a conference,
it prevents the conference participants to hear the hold music while
the 200OK is back.
