on say a d12 or r15. if one doesnt have a phone line to use but does have internet. is it possible ( i already doubt it) to use an adapter for ethernet cable to usb adapter to hook up to the ird to be able to do a call back so i can order ppvs? ive read that the d11i uses it but only because it uses a special dish setup. im not looking to connect to the internet or anything just want to be able to do a call back with out having to pay for a phone service that i most likely wont use.
