Internet service provider EarthLink, Inc. announced Tuesday a Voice over Internet Protocol (VoIP) service for its high speed access subscribers, allowing them to make free online calls to other compatible users.
Available to all 1.2 million EarthLink High Speed access subscribers, EarthLink Free Online Calling allows two or more users using the Session Initiation Protocol (SIP) standard to talk to each other over the Internet for free anywhere in the world. Those who sign up will receive a username, password, and a SIP address along with a 7-digit number other users can reach fellow users at.
Unlike some other competitors, EarthLinkis new service will not allow VoIP users to call traditional landline or cellular phone numbers. Other services charge an additional fee to call non-VoIP phone numbers via their personal computer.
EarthLink is recommending its VoIP users use a headset or an ATA (Analog Telephone Adapter) with its service. EarthLink Free Online Calling comes with voicemail, three-way calling, an online log of the calls you make and receive, and online account maintenance.
The service is not available to EarthLink dial-up customers. EarthLink high speed service costs between US$42 to $50 per month, depending on the service area.
