Is it possible to have 2 separate Google Voice phone numbers?

Can I get 2 Google Voice numbers? I have a single phone number issued by AT&T. I can sign up, but the verification process requires me to enter a phone number to link and as soon as I enter the phone number to link, the previous Google Voice number gets disconnected. From [their official docs](https://support.google.com/voice/answer/165221?co=GENIE.Platform%3DAndroid&oco=1) , it appears you can have just 1 GV number - 1 phone. > You can link up to 6 numbers. You can't link a number that's already linked to a Google Voice number. So is there any obvious loophole that can be used to get 2 phone numbers?
