I am using google voice on SP1. The cell is setup as a forwarding phone in GV. So, when someone calls me on the GV number, it rings my cell and my home phone (connected to obi on SP1). This is a new problem on an old setup. Basically, when someone calls my GV number and i pick up on SP1, i can talk for a while, the my cell phone randomly rings by itself. If i pick up, it gets added to the call, but if i hang up the cell, it hangs up on all lines. I followed the tutorial verbatim and have nothing customer. I haven't tried resetting or starting over.
