Some of you may make calls from Gmail. Especially international calls, and while Google Voice offers great prices, you can still blow through the minutes you’ve purchased.
The Google Voice team says:
So based on your feedback, we implemented the ability to auto-recharge your account: just go to your billing page (click on the add credit link next to your balance) and select the recharge amount. When your calling credit dips under $2 or 2€ we will automatically charge your credit card on file for the selected amount.
This is actually pretty handy, because it’s easy to run out of minutes, and who wants that to happen during an important call?
