Is there an app which would use wi-fi to make outbound (and possibly inbound too, but not necessary) calls from my android phone?
I am already aware of Groove IP and the SIP options and their integration with Google Voice, but that is *not* what I am asking. I want to make wi-fi calls when I am near wi-fi but still use my t-mo phone number (just to save the mins). I am OK with receiving calls on the t-mo network.
I have seen something like this in a Samsung t409 feature phone I used to have. It used to call using wi-fi when I am wi-fi connected, and not use the cell minutes.
