S-unno (formerly MediaRing Talk)

Formerly known as MediaRing Talk, S-unno is a software program that allows you to call your friends and family, organize conferences and communicate via an instant messaging service. It can be seamlessly figured out, even by users with minimal experience in such apps.

Upon initialization you are required to create an account that must be validated through your email address. Plus, you can use a wizard to adjust audio tuning by carefully following the program's instructions, as well as specify your country.

The interface of the application is familiar to the one of a common instant messenger, so its layout is well-organized. It is possible to create and manage groups that contain your friends, family, coworkers and other acquaintances, and you can add a buddy to the list by mentioning his or her community (e.g. Yahoo Messenger, Google Talk), ID or username, a group and greeting.

S-unno allows you to make worldwide calls to your buddy list or any other numbers, send SMS messages, review your recent call records, pick an image as your account avatar (BMP, PNG, JPEG) and change your status (e.g. to away or busy). But you may also create a phonebook of contacts, host a conference call and configure call forwarding settings.

Other customization parameters are available via the Options screen. For instance, you may set S-unno to automatically run at system startup minimized to the system tray and to log you in automatically, configure proxy settings, enable sound alerts when buddies come online, select another font for the chat text and use encrypted signaling.

The program has a good response time, contains user documentation and runs on a moderate amount of CPU and system memory. We have not come across any issues throughout our testing; S-unno did not hang, crash or display error dialogs. Thanks to its intuitive layout and resourceful customization preferences, S-unno should be appealing to both first-time and power users.
