You can dial a toll-free phone number with ooVoo, but there will be a charge for the call. ooVoo Credits will be deducted from your account just as they are when you dial any other phone number.
Unfortunately, we are no longer able to support the sale of ooVoo credits, subscriptions, or premium video plans for PC or Mac.
If you currently own any credits, your credits will expire on the earlier of sixty (60) days after you purchased the credits or March 31, 2017. Therefore, you must use all of your credits before the earlier of sixty (60) days after purchase or March 31, 2017. Any credits you hold after that date will not be valid.
