I can call with GV using Google's mobile portal, but that causes my cellphone to ring, then calls the other line, so it's still using the voice network. This is a problem for me as my goal is to be able to make free North American calls from outside my local area (Vancouver). I want to make the calls over 3G or WiFi, as data does not have any roaming charges within Canada (at least from my provider, Rogers).
I finally found a SIP client for my Blackberry, Blackvoib, but I don't know what to do from this point on. freephoneline.ca charges $50 to get the SIP password to be able to use third party SIP clients. Any free alternatives? I figure there might be something to do with this IPTel stuff that was posted before but I didn't really understand it. Whatever the setup, obviously I must be able to receive the confirmation number call from GV when I add the SIP-enabled number.
Can someone help me out? I paid Rogers $2000 after spending a month in Toronto, even though I was making Toronto-local calls and half of it was for receiving :'(
