I just set up my OBi100, and I was wondering if there was a way to set up antisip with it? Previously I used an antisip login with IPKall and Google Voice using a telephone adapter. IPKall is no longer supporting PSTN which is why I switched to an OBi. The thing is, most of my family uses antisip, and I'd like to still be able to use my antisip login. Is there a way to make this work?
