GVoice to Gvoice through asterisk

Hello, I am using PBXinaflash, with asterisk, and I am trying to connect through asterisk with google voice. I would like two google voice numbers to be able to talk to eachother, though the asterisk server. Could I get a bump in the right direction, cause I am not seeing how I would be able to do this. Thanks guys

Do you want to do this in a GUI or do you want to get your hands dirty an write Asterisk DialPlan code?

If you want to use a WebGUI - PBXinaflash forum might be a better choice.
