TIPS FOR VS4000 
The volume control for the VS4000 controls the incoming far side audio and the local tone generator.  It 
does not, however, control the sound effects inside the units such as incoming call ring and the female 
speech that occurs when you dial a number.  This is important to note because if the volume control is very 
low, it may appear that the codec audio is fine because the sound effects are still generated and will be 
heard in the local room.  However, when a call is connected, the local side may not hear the far side 
because the local volume control is too low.  Since the local participants heard the sound effects audio at a 
normal level, it may not be obvious that the volume control is set too low. 
 
The sound effects volume control can be adjusted in the System Info, Admin Setup, Phone Audio page.
