Thanks Yuan.  I beg to differ with the developers if there really is no
amplitude control on IP channels.  I have an application where I am
studying the spectrum of recorded voice.  When I call into my Asterisk
box I have to hold the phone away and speak softly to avoid clipping the
recorded waveform - clipped waveforms play havoc with the spectrum.

I guess it is time to study the source code (ugh!).
