So outgoing PTSN calls are fine but incoming PTSN calls have poor 
quality.  Do both parties hear the crackling, etc?  Can you reproduce 
this, ie if you use your cell to call in, does the problem occur every 
time?  What happens if you call your PTSN number from your handsets?  
Does the call go out onto the PTSN and come back in with poor quality?

Do you have other phone lines you can try the A200 with?  Have you asked 
Sangoma support?
