Business communications these days are multi-dimensional. For an enterprise, the solution is unified communications – which traditional PBX phone systems can’t do. Interactive Intelligence designed the Vonexus Enterprise Interaction Center IP PBX software to replace one-dimensional PBX equipment. First, Vonexus EIC was developed on a Microsoft-based architecture — and used the SIP standard throughout for Voice over IP. Then real-time applications for converged voice and data were pre-integrated, now for the mid-sized enterprise, Vonexus EIC unifies communications in one pre-packaged solution.
