Google Voice - problem w/o data connection

[tcope]

I've been trying to wrap my head around this and it's probably an obvious answer but why can't I dial out using my GV number unless I have a data connection active? Per Google and from what I can see, no VoIP is being used and it seems to me when I have a data connection and use GV to dial out it just dials a Google number first. I'd think the call would be made to GV, GV would patch the call through to the person being called and pass on the GV caller ID number. So why does the app need to have a data connection to work?

How will GV on Google's server know what number to dial and your account info without an Internet connection?

I guess the dialed number cannot be sent to Google via the phone call? This would not follow the current way the calls are placed but I guess an app can't fake the caller ID?

We can speculate about how they could perhaps implement this using just voice but the bottom line is they did not choose to do that.
