Skype with Google Voice

If you have a Skype number for incoming calls, and are registered with Google Voice, it occurred to me how you can make domestic phone calls through Skype for free.  Go to Google Voice, type in the number you want to call, tell it to ring your Skype number, and hit “Connect”.  Skype will ring.  Pick it up, and Google will dial the number you entered, and Google Voice will connect you..  Voila: a free Skype call.

This will only work if you have registered your Skype number with your Google Voice account, which is straightforward.

If this is blindingly obvious, sorry for the bandwidth.
