And the 841 speaker phone is unusable - it continually compensates the 
volumn of the speaker to reduce feedback in the mic  and the sound level 
in constantly going up and down.  If you are listening to a conference 
call and can push the mute button you can listen just fine but if have 
to be able to converse it doesn't work to do it with the speaker phone. 
  The newest firmware made it some better but still not enough to use - 
at least not in a small room.
