Its a review about this product
Pros;
1. Price,
2. Two line,
3. Decent display, (but see below),
4. Large area to write names for speed dial,
5. Decent sounding speakerphone, though 'tinty',
6. Battery backup for power failure, but time still has to be reset,
7. Auto busy redial: keeps on dialing every 30 seconds if line is busy (a rare feature),
8. Fairly large footprint, but not too big.
Cons;
1. New call indicator can't be turned off. Even if you answer the call on this phone, indicator still lights. I solved this by putting a small piece of electrical tape over the surface mounted LED on the circuit board for each line.
2. Display backlight is dim,
3. Base isn't angled up far enough. I cut a 1x2" piece of wood to prop up the back of the base so the display can be seen easier.
This VoIP issue with the hum should be fixable. It is just a ground loop, fixed by reversing the two wires from your POTS line. This worked for me!
