Computer interferes with phone volume

Question

My mother's new (used) eMac causes a drastic lowering of the volume of incoming phone calls. She doesn't even have to be using it--it simply has to be plugged in! If she unplugs it, callers on the phone can be heard perfectly again. All filters (wall jack) and wiring are correct. The phone is a Uniden 5.8 GHZ cordless; the phone and Internet provider, AT&T. Any advice at all from any smart person would be greatly appreciated. Thanks in advance.....macquest

Hello again,
My next suggestion would be to try replacing the filter. These can be temperamental and trying a new one may resolve the issue. Normally, an ISP will supply more than one with your modem so you might want to check to see if you have more in with the packing materials that came with the modem if you still have it.
Additionally, certain volume settings are held in the PRAM settings. I know it is the phone volume that you have said is lowering but I am wondering if the computers volume levels could have anything to do with the problem.
See: Mac OS X: "What's stored in PRAM"
You may want to try resetting PRAM. In the article linked to, there is a link in the left side bar for how to reset PRAM.
This should not hurt anything but you may need to reset certain settings afterwards such as date & time etc.
