In reply to David H. Deans.

Thanks for your question David (and good to hear from you again). We do believe that more and more voice traffic will be handled or supported by WiFi networks (essentially wireline as opposed to cellular). This will be enabled by a combination of broader WiFi availability (at home, at work, public hotspots, and on the move with many private vehicles and public transportation offering WiFi access) as well as more VoWiFi service offerings from a variety of service providers. Service Providers will be able to track and distinguish this traffic based on the growing level of intelligence that exists on fixed and mobile networks today (i.e., service or application awareness). The need to track carrier grade voice services is essential for two primary reasons – 1) to monetize (at some level) these voice services, and 2) to prioritize these voice services so that a consistent, high-quality call experience (as you have referenced) is delivered. Voice and video applications are generally given higher service priorities than email, web browsing, instant messaging or other services that are not adversely affected (noticeably) with higher network latencies.
