I just bought a RadioShack ET-3222 Trim Style Phone and I cannot dial any numbers out. I do not see a talk button on this phone so after I dial the number it does not ring it just gives me a dial tone. I hear the numbers dial as I push them but, I just can not call any one. I wonder if I am doing something wrong or is the phone I bought just defected? Please help. decm12@gmail.com
