Doesn't Bell have a department for helping people with medical issues?  
Seems to me they used to.

How do you know it's Bell's problem.  All we know is something changed 
when she moved.  I defy anyone to listen to a good analog line and 
compare it to a digital line and tell me what the difference is, other 
than perhaps better quality audio on the digital line.  You can consider 
things like level, frequency response, phase shift, noise, distortion 
and more.  Incidentally, when digital trunks started to be used, people 
complained they were too quiet!  They were used to all the noise that 
accompanied analog calls.

BTW, many years ago, I used to measure those things on various circuits, 
including the CBC radio feed in Northern Ontario.
