Keynote Systems, a VoIP monitoring solution provider, has released VoIP Competitive Intelligence Study, a report comparing the performance of eleven consumer VoIP services in the U.S., as well as assessing market readiness for VoIP in San Francisco and New York, and evaluating network carrier performance based on end user perceived quality. The service providers measured in the study included AOL, AT&T, Earthlink, 8×8, Primus, SunRocket, Time Warner, Verizon, via:talk, Vonage and Vonics Digital.

The company measured ten performance factors including service availability, average number of call attempts, dropped calls, outage minutes, average MOS, MOS geographic uniformity, average audio delay, percentage of calls within an acceptable audio delay and audio delay geographic uniformity. The factors were aggregated into two indicies including reliability and audio clarity. A total of 190,000 calls were placed during the study, resulting in over 17,500 calls per VoIP service provider and over 30,000 call per network carrier. Data for the study was collected between November 18 and December 31, 2005.

The company finds that among all services measured, service availability was 99.1%, up 2% from June of 2005. Three service providers – Time Warner, Vonage, and Verizon, achieved a MOS of 4.0 or better, with Time Warner leading all with a 4.11. Five of the eleven services had a MOS lower than 3.5, which is not only under toll quality audio but below the standards established for wireless phones.

Audio delay for all VoIP services was twice that of calls placed on the PSTN.

Time Warner ranked first in reliability and audio clarity. The cable operator’s average availability was 99.91%, compared with 95.1% availability from the lowest ranking service provider. Verizon DSL was recognized as the most reliable network carrier in the study.

The report includes detailed results, custom analysis of the data and all raw measurement data.
