Custom outbound CallerID / spoofing with Google Voice?

[WiFied]

I am currently using PhonePower with my Obihai unit. PhonePower allows me to enter any number I choose as my Outbound CallerID. I'd like to get rid of the PhonePower bill and go back to just having Obihai use Google Voice. But, will I still be able to configue Google Voice with a custom Outbound CallerID?

No.  Google Voice doesn't support caller ID spoofing.  It's just too vulnerable to abuse (think stalkers, ex-spouses, people pretending to be your bank or credit card company, etc.)

What is the cheapest way to do this? Ring-To + the $12/yr. for E911? Any free SIP to do this with Google Voice?
