   YakToAnyone is a newVoIP service based on the Ineen engine. Similar to Skype, YakToAnyone offers long distance service from computers to phone numbers all around the world starting from $.02 per minute and computer-to-computer calls for free. The telephony service requires no monthly commitment and users can buy credits directly from a credit or debit card. International calls can be as cheap as $.02 per minute to first-world nations but rates can escalate dramatically when calling third-world or remote nations. YakToAnyone also offers video phone services and accessories that make your existing phone compatible with the service.
