Voxofon has had a BlackBerry app for awhile now that lets you automatically use their service to make cheap long distance calls. If you just need cheaper calls for yourself you can just sign up on their website. We did not mention it before since these calling card services seem to be a dime a dozen recently.
Where things get more interesting is with Voxofon’s business solution. They provide each business wit one account which has sub accounts for each of their employees. The company will then receive a monthly invoice with each of their employees bills broken out separately. They also have prepaid accounts for business.
With no monthly fees or subscriptions this could be a great way for companies to save some money on their employees long distance calls during this economy. There is really no risk or commitment to signing up so I don’t see it hurting to try it out.
