Shawn, descript DC/AC line characteristics more detaily and i can help you. I done devices like you asked about but for Russian phone standart. (DC=60v AC call=120v/25Hz) The main idea is to control connection the phones to the line through some switch and when AC ringing is appear than make this switch open. WBR Dmitry.
