Solutions for Real-Time Communications

The success of any organization, whether large or small, depends on the effectiveness of that organization’s communication tools within the enterprise as well as between the enterprise and its customers. The move to Session Initiation Protocol (SIP)-based communications requires that enterprises revisit their network security and embed a layer of intelligence in order to get the most value out of their move to real-time communications. Sonus Enterprise Solutions help enterprises truly unify their communications networks and overcome their SIP and Unified Communications (UC) challenges:

  • Complexity of multi-PBX for routing and dial plan management
  • Disaster recovery challenges
Migration Challenges
  • From Time Division Multiplexing (TDM) to IP PBXs
  • From Primary Rate Interfaces (PRIs) to SIP trunking
  • Interworking of SIP and H.323
