VoIP/Unified Communications

VoIP and Unified Communications are becoming main stream on converged networks. VoIP/UC are unusual in that they generate different types of traffic: not only voice streams but also signaling flows, as well as video, instant messaging or even P2P file transfer. Another peculiarity is that VoIP and video are very sensitive to changes in performance. While a file transfer can easily be slowed down without disturbing users, this is not possible for phone communications. Given the importance of user acceptance in a VoIP or Unified Communications project, controlling and measuring network performance is crucial.

With Streamcore Branch Office solutions, enterprise can benefit from:

• Advanced Visibility:
  • Benefit from usage reporting between the different types of Unified Communications traffic: audio / video / IM / email / …
  • Follow VoIP quality (MOS) and signaling performance measurements (call management, IM, presence…) per site and even per communication
  • Use true real-time troubleshooting (last 10 seconds) to determine if the WAN is the root cause of the performance degradation.
• Dynamic Performance Control:
  • Activate advanced QoS mechanisms to reserve bandwidth for real-time traffic such as VoIP or video and to automatically prioritize interactive signaling messages (e.g., SIP). 
  • Ensure that business application performance are protected when competing with Unified Communications bandwidth-hungry traffic (e.g., P2P file sharing)
  • Guarantee quality of videoconferencing
