Hi,

There are more than one sound problem left I think.
I encountered the same problem when using voicerecording, but I don't 
use it on my own right now. Also I know that I'm not the only one having 
the effect then picking up the handset to hear the last 1-2 seconds of 
the last made call... - not nice either.
...someone said hope's dieing last - I don't think it would last long 
anymore :(
