Google Voice Call Quality -- How is a call routed if you have GV make the call?

[Jay3]

I use Google Voice (love it) primarily because of it's visual voicemail on my Droid. I do have a Google Voice number, and I'm trying to decide whether to set the Droid app to "make calls using Google Voice" or not.

I have no problem with giving out a different number, and my placed calls seeing the GV number in caller ID.

My question is, does this affect how the call is actually connected, from a quality standpoint? I tired a call both ways, and the sound quality seemed a little bit different. But then, I am an obsessive compulsive weirdo.

Does anyone know? Is there any difference in call quality or routing between making a native Verizon call and a Google Voice call on Droid? (Like, does Google voice actual use 3G to connect to Google server over the internetz, then place the phone call?)

Bump -- anybody know the answer to this?

Finally, GV does NOT use the 3G connection, as I can't connect to the internet while on a GV call. That indicates to me that it's using the normal voice channel.

Yup. GV is not VOIP. I'm not sure why people assume it is. That's why it uses voice minutes if the access number isn't in your circle/list.
