Now you don't need a computer to make free Internet calls. A new breed of phone instruments that use Skype promises to skip the need for a PC and deliver the same clarity. Both you and the person you call have to be logged in to a broadband connection to use a Skype phone.
The Security concerns for this unique service is nil. Unlike mobile phones or landlines, you don’t need any ID proof or verification to get a Skype account and call people, which is rather alarming for the security agencies. Skype calls are encrypted, so there is no known way for anyone to legally or illegally listen in on your calls. Skype is not a replacement for your ordinary telephone and can’t be used for emergency calling. Both you and the person you call have to be logged in to a broadband connection to use a Skype phone.

Skype: legal and security implications - One doesn’t need any verification papers or ID proof to set up a free Skype account. That alone is worrisome for security agencies worldwide. Skype calls are also encrypted, making it technically impossible for anyone to legally monitor a call. Meanwhile, several developed and developing countries around the world are embracing and allowing the proliferation of Net telephony and services such as Skype. A ground-breaking recent announcement from Trai finally removes all restrictions on Net telephony in India, and permits Internet Service Providers (ISPs) to allow users to make calls from computers to fixed landlines and mobile phones, both inside and outside India.
Without A DOUBT Net telephony with ubiquitous broadband and Wi-Fi zones will one day outnumber traditional phones, especially since it costs nothing
