I am a novice. I manage a business and have purchased a T48G instrument I want to use it simply as a desktop phone (sometimes with headset). My RG is an ATT Uverse modem (ATT560). I have connected an Ethernet cable between the modem and the T48G and get dial tone. I get nothing but busy signals for any number called and no incoming. I would prefer to go wireless and need to know if there is anything special about the needed dongle. What am I overlooking. Something dumb I am sure. Please help a greenhorn.
