I am trying to cut the cord with all traditional carriers. My company provides VoIP services so I am putting that on my phone. I have even pulled the chip out to make sure that there is no carrier. I installed CSipSimple and it works fine. However, when I call from my contacts it still asks me if I want to use VoIP or mobile. Worse, the bluetooth hands-free in the vehicle always connects to mobile and so fails. Has anyone worked all of this out yet? I have tried various config changes on the phone and CSipSimple but to no avail. I am not married to CSipSimple by the way but I do want a straight VoIP solution. I don't want to use Google Voice, for example, while I provide my own VoIP service.
