With Skype’s free software is possible to hold telephone conversations over the Internet using a desktop or laptop computer. PC-to-PC calls are free while charges are made for calls from PCs to land lines or mobile phones.

Intel has said that with Skype version 2.0 or higher there is a conference call feature that can include up to ten people at the same time — but that’s only possible if the computer’s processor is an Intel Centrino Duo or an Intel Pentium D processor.

The conferencing feature takes advantage of the multi-tasking capabilities of Intel dual-core processors, Intel said at a Skype page within its website.

The two companies are planning additional feature extensions and optimization of Skype for Intel’s dual-core processors, Skype said. Later this year, Skype will release video calling optimized for Intel dual-core technology, the company added.

“Through our partnership with Intel we can ensure that Skype performs better than any other Internet calling application and drive widespread business and consumer adoption,” said Alistair Shrimpton, general manager of Skype UK, in a statement.
