Maybe I got a defective one, but there was a slight humming sound even before it dialed (and no I am not talking about the dial tone). The sound was more noticeable with some phones than others, as some accentuated the frequency interference that this device added to the line. Again, the problem was the device and not Skype.
I bought an Actiontec Internet Phone Wizard instead and the noise was gone completely. So maybe I did get a defective unit, but either way there is probably some quality control issues with this device, or maybe all of them have the noise and some people don’t notice. It’s up to you to decide. With the Actiontec or DLINK, it will probably be much much clearer.
Also, the people posting saying you cannot dial out if you do not have a land line are COMPLETELY WRONG. You download the latest software, right click the system tray icon and choose advanced, then change the default mode to USB instead of POTS. Then you can dial by doing:
“001 areacode number #”
This will dial skype from any phone… If the device didn’t have that interference to it, then I would have kept it as the software and functionality is very good, even without a land line.
