Currently I have one of the new Ubiquity phones on my desk. There handsets have a mute button, 
or if you want a "speak" button, but a phone running under Android for government usage might 
leave some questions unanswered.

If your phones have some functions keys, you'd have a look at the MuteAudio function and map the 
states to DTMF sequences, which in turn are mapped to the function keys. This makes you rather 
independent from any hardware and you might adapt the behavior depending on what your clients 
wishes will finally be, if they ever find out themselves.

What I don't understand is why the normal mute button on most headsets is not sufficient.
