Can't sign up for Azure - "We were unable to verify your account"

Anyone else have this problem?

I cannot sign up for an Azure account.

On the registration page, it asks for your phone number and wants to confirm it by sending a text or calling you. I only have a Google Voice number, and I always get

We were unable to verify your account

No matter if I choose text or call. There is no way around it. Any help?

EDIT: Other posts have indicated it's a problem when your country isn't listed, but that is not the case here (I'm in the U.S.). Those posts suggest calling "your local Microsoft branch" but how do I find that?

After reading the comments above, and calling Microsoft myself, I was told the verification process does not support Google Voice or Skype phone numbers.

The person I spoke with on the pre-sales department of Azure said he could not manually create an account for me or validate my Google Voice number, despite me sending him this question on StackOverflow showing that others had been successful in calling Microsoft as I had.

My solution was to use a friend's number and have him send me the verification code he received. However, it must be within the Azure signup's session timeout period or the code is no good.

I really hope someone at Microsoft sees this and corrects it for future customers.
