from VOIP Pulse: Skype is set to end its promotional calling service that allowed its users to place unlimited calls within North America at no charge. Beginning in 2007, the provider will allow customers to make calls within North America by per minute charges or pay $14.95 for an entire year of unlimited N.A. calling. The rate will go up to $29.95 in February. During the promotional phase, Skype is giving subscribers 100 minutes of free international calling as well as coupons for hardware that works with the Skype service.
