communications management market, today announced that Avaya selected its 
Application Suite software for use in its converged network, which is being

comprehensive, fully scalable solution will allow FIFA to significantly reduce
the cost and complexity associated with managing and monitoring the internal and

Avaya and FIFA have once again placed their trust in MTS' software and support
services to manage their complex communications environment for such a
