Thought I would post on my setup. I just purchased and setup Obi110 with 2 Google Voice accounts (mine and my wifes). Setup was very easy and is working fine. I even figured out how to have home phone have different ring tones for each gv account. My landline, a Comcast line, is connected to the line port. I have not used this Comcast number in a long time and mostly incoming calls on this line are telemarketers. I like to have this connected to my Obi110 for e911 purposes, but I don't want it to actually ring my home phone. I want it to go straight to voicemail. So after playing around, I got this to work by: Under Ring Settings, Ring Profile A, changing ringtone 10 to blank and then setting line port to default ring of 10. Bingo - works as I wanted.
