I understand that GoogleVoice is effectively a broker between a caller and reciepient; but when does GoogleVoice use VOIP and when does it use traditional connection?
There is a number(?) of scenarios I can deduce:
PC-PC: VOIP for sure
Can someone help me with the scenarios below:
1) real cell phone that has GoogleVoice app installed. Calling out of GoogleVoice app to non-GoogleVoice number... is it VOIP or not?
2) real cell phone that has GoogleVoice app installed. Calling out of GoogleVoice app to GoogleVoice number... is it VOIP or not?
3) real phone calling to GoogleVoice number that is linked to (not ported to) the real phone having a GoogleVoice app.
4) real phone calling to GoogleVoice number that is not linked to (not ported to) the real phone having a GoogleVoice app. In this case the voicemail would kick in
