I was wondering if my HD-DVR can do caller ID thru the ethernet port. I only have one phone jack near my receiver, and I have it networked. The only thing is that I don't have a way to run a phone line to thed phone jack on the receiver. If not, does anyone have an idea how I can get this to work besides a wireless adapter? Is there a splitter I can get it to work? I have Comcast HSI and digital phone. Thanks.
