A milestone for Avaya and business communications broadly, Avaya Aura goes beyond existing telephony and data communications networks and introduces a platform that unifies all forms of communication (voice, messaging, e-mail, voice mail, and more), without sacrificing any of the resiliency, security and performance that Avaya communications systems have always been known for.
