Cordless DUALphone

PCMag has a review up of the RTX USB DUALphone and writes, “Despite operating in the crowded 2.4-GHz band (also occupied by 802.11b and g devices), the phone generally provides clear audio. I also noticed no performance problems due to interference. The good connection could come from the built-in Digital Enhanced Cordless Technology (DECT 6.0), which is Wi-Fi friendly. … No more headphones tethering you to a PC when you want to make a VoIP call. This easy-to-install cordless helps you get more out of your broadband connection with Skype, and it works with your traditional landline, too.”
