A Milan-based VoIP provider has filed a complaint against Microsoft’s purchase of Skype, arguing that it is a Skype competitor and will be hurt if the free VoIP service is built-in to Windows operating systems.

The company, Messagenet, not only wants to block the bundling of Skype from Windows, but wants regulators to give Skype competitors access to Skype’s subscribers to allow services to interconnect.

The $8.5 billion Microsoft-Skype deal has already gained U.S. approvals. The EU is expected to rule on the deal sometime this week, though the Messagenet complaint may delay the decision.

Voip-Pal.Com Inc., has announced that it is continuing free local and long distance VoIP services to consumers and business owners.

“We have been offering a Free Trial on our VoIP services for about a week and the response has been very positive,” Dennis Chang, President of Voip-Pal, said in a statement.  ”New users will be able to experience the quality and ease of our services now without making any initial monetary commitment. We are looking forward to converting the people who have taken advantage of our Free Trial to full time users of our services.”

Chang said that once a new user registers, they can begin making free calls to almost anywhere in the world. They can call from a downloaded PC Dialer or call from their cell phone or land line, he said, adding that users can select a local Access Number and create multiple contact numbers to call and that, once registered, calls are automatically authenticated and routed. A smartphone is not necessary for the use of Access Numbers – you can use any cell phone, he said.
