The principal conclusions of the study were:
  1. Overall, the one-way listening speech quality provided by the combination of Microsoft’s client and USB handset was consistently better than that provided by Cisco’s IP phones and Call Manager, whether using G.711 or G.729.
  2. More detailed analysis showed that the mean transmission bandwidth of the Microsoft solution typically fell between 24kbps and 80kbps, which are the bit-rates of the Cisco solution with G.711 and G.729 operation respectively. The peak bandwidth of the Microsoft solution was 100kbps for some IP conditions.
  3. In general, the maximum recommended value for round-trip delay is approximately 400ms, i.e. a one-way delay of 200ms. The delays observed for both Clients with low IP impairment conditions are within, or close to, this budget, although it should be noted that control of the delay budget within VoIP networks remains essential.

  • When it comes to storage, not all data is the same. Different data has very different performance and capacity requirements. With the explosion of unstructured data – 80% of data growth worldwide is unstructured data – the landscape has become even more complicated. Make sure you have what you need to handle all this data and store it appropriately. This brief, "Top 5 Reasons to Consider Veritas Access," describes how to manage your data, so it's easily accessible regardless of where it resides …

  • For the first time in decades, IT leaders now consider all-flash storage as a strategic IT asset.  IT has become a new operating model that enables self-service with high performance, density and resiliency. It also offers the self-service agility of the public cloud combined with the security, performance, and cost-effectiveness of a private cloud.  Download this MIT Technology Review paper to learn more about how all-flash storage is transforming the data center.
