Philips PH0900 Wireless Phone/Modem Jack System - Cordless Landline Phone with Caller ID & Answering Machine for Home & Office Use

I've been trying to figure out how to get the fax part of my Dell all-in-one printer working, since it was no where near a phone jack, and this wireless jack fit the bill. I followed the directions plugging the base unit into an electrical outlet near my landline, plugging the line into the jack as well as the land line. I then plugged the extension unit into an outlet near my printer/fax unit. The indicator light turned green (signifying that it found the base unit signal). I first plugged a phone into it to see if I was getting a dial tone. There was a buzz on the line, but I did hear the dial tone. I have read some other reviews complaining about static on the line, and with the buzz I heard I'm not sure I would want to use this for another phone line, but when I plugged my fax into this and ran a test, it worked great...no complaints! Both units are not too large, and I am happy to now have gotten the fax working!The directions said not to plug the units into GFI plugs (the plugs with the little rest/test buttons), and I suspect how well it works depends on the wiring in your house, but for me it works great and will allow me to give my old fax (that I would drag out whenever I needed to use it) to Goodwill.
