Vapps announces an alliance with Windows Live Messenger to offer free conference calling services to the 255 million users of Windows Live Messenger through a convenient activity.

Windows Live Messenger, the next version of MSN Messenger, is the world's largest easy-to-use consumer instant messaging service that allows people to connect with others in real time, expressing themselves in a rich, convenient and fun way. Users of the conference calling plug-in will be supplied with a conference bridge number as well as participant codes for use by up to 500 participants simultaneously. A variety of services will be available through the conferencing activity including, standard call management (volume control, muting, participant announcing, conference locking and recording) along with sophisticated moderator features for Web-based on-demand call control.

The conferencing activity will allow users of Windows Live Messenger to enhance their instant messaging experience and enable them to connect simultaneously through voice conferencing with their growing network of friends, family and colleagues.

"The evolution of conference calling has taken a giant leap over the last 12 months with the adoption of conferencing services by consumers using the internet as their communications platform," said Ben Lilienthal, CEO and co- founder of Vapps. "We are pleased to have the opportunity to extend our services to users of Windows Live Messenger and offer premium conferencing capabilities to the growing number of users across the Web."

Windows Live Messenger is free to download and is available in 26 languages and is used in more than 60 countries.
