Once you do this, go back to sipgate settings like before and choose test phone. Mine was showing offline until if did this exact process.
This was a pretty convoluted process, but I think I got it to work. mostly. This did give me a headache, but I don't like not figuring things out once I start. One question: Outbound calls can only go to land lines? I tried calling my wife's Sprint number and she could hear me but I couldn't hear her.
