Hi, one of my clients has a DSL connection at his cottage in Stoney Lake.
His SIP extension kept failing and was tracked down to the Analog line carrying 
the DSL
This was a "no brainer" when I listened to the line on an ordinary POT. after 
breaking dial tone I could
here all sorts of weird noises so I traced back the cable to the demarkation 
point (a small box attached
to the outside of the house). The box officially belongs to Bell so I opened it 
anyway, the two
connections inside showed signs of corrosion (green mold), from my old days I 
remember that this type of
corrosion
can emulate a resister, a diode, zener diode  or a random noise generator 
depending on temperature and
humidity. Anyway, disconnecting and thoroughly cleaning the connections and 
cable completely cured the
problem. I would check this out before calling the phone company as their 
equipment can often miss these
problems and might save you a 10 day wait for some one to come out to fix the 
problem.

Good Luck
