VoxOx is s a new Web service launched recently by TelCentris. VoxOx is probably the first universal communicator that combines the IM/e-mail/social networking functionality with free voice. The software interface is very much like iPhone. The key features of VoxOx include a unified meta address book which contains contacts from all the various services and social networks; VoIP telephony with two initial hours of free talk time; inbound/outbound calls; voicemail; call forwarding; inbound faxing and fax-to-e-mail; instant messaging for MSN, ICQ, AOL, Jabber, Yahoo, and Google; video conferencing; e-mail; two-way texting; and file sharing up to 100MB. And the best of all, VoxOx gives out a free phone number for each user. This means your students, friends, and colleagues can call you right on your desktop. VoxOx is currently available for Windows and Intel-based Macs, with versions planned for Linux, PowerPC Macs, iPhone to be released soon.
The VoIP service is similar to Skype in that calls are free between other VoxOx users. However, VoxOx users can make free outside calls as long as they are willing to frequently view video ads to rack up points for minutes. Each point equals one minute of call time. Also, users can get free minutes each time they recommend the service to a friend.
I have tested VoxOx for the past few weeks and I like it so far. VoxOx is simple to use and has many great features. As a regular Skype user, I find the call quality is as good as Skype. Though VoxOx is still very much in beta, I think VoxOx will be a strong Skype competitor. You can try VoxOx out by downloading it here.
