Social network website MySpace has joined forces with internet phone firm Skype to allow MySpace users to make calls to each other.
MySpace has more than 110 million users
With the service, which starts from the end of November, the two firms say they are creating the world's largest online, voice-connected community.
MySpace users will be able to place free internet calls to other people on MySpace, or to Skype users.
In addition, MySpace users will be able to pay to call landlines and mobiles.
The Skype option will be added to MySpace's existing instant messaging feature, and will not require MySpace users to download any additional Skype software.
"Internet calling is the natural next step for how our members communicate with each other," said MySpace chief executive Chris DeWolfe.
No financial terms of the arrangement have been released.
MySpace has more than 110 million users, while Skype has 220 million.
