I take it you've also not had the problem where the handset microphone 
stops working. (This is apparently already fixed and will be available 
in the next beta firmware release (1.1.6.x), when they've fixed some 
more problems that have been very difficult to track down.)

I'd like to go back to 1.1.5.15 if nothing more than for the improved 
audio quality and the on-hook dialling.
