Does anyone use this device incl. CNIP = Calling Name Identification Presentation (CLIP = only the number and CNIP incl. name from online phone book)? CNIP works e.g. with tel.search.ch and shows phone book entries there! But when I look at the photos of this device, I don't see an Ethernet cable. Or does it have WLAN to query the online phone book? Thanks for any experience reports and
