Keynote Competitive Research, the industry analysis group of Keynote Systems, today announced the top-line results of its newest study of voice quality including VoIP, packet cable and traditional phone service (PSTN). The new study reveals that while packet cable digital voice and Voice over IP offerings still lag in quality, they are proving to be highly competitive with traditional PSTN service providers. This finding is of great significance to VoIP providers who are under increasing market pressure to understand and prevent high rates of customer attrition and churn in a rapidly changing market.
“As VoIP catches up to traditional phone service and reaches new business sectors, it is important that studies like Keynote’s are available to potential and existing VoIP customers so they can make informed choices regarding service providers. It also encourages healthy competition among the providers, catalyzing competition that ultimately benefits the industry overall,” said Jessy Cavazos, industry manager of Frost & Sullivan’s Test & Measurement practice.
The benchmark study examines voice services from leading providers including AT&T CallVantage (NYSE:T), AT&T PSTN (NYSE:T), Comcast Digital Voice (Nasdaq:CMCSA), Primus Lingo (OTCBB:PRTL), Packet 8 (Nasdaq:EGHT), Sun Rocket (Closed 8/07), Digital Phone from TimeWarner Cable (NYSE:TWX), EarthLink trueVoice (Nasdaq:ELNK), Verizon VoiceWing (NYSE:VZ), Verizon PSTN (NYZE:VZ), Vonage (NYSE:VG) and Vonics Digital. The data for the study was collected over a one month period, from June 1 through June 31, 2007.
In order to benchmark and rank the quality of consumer voice services, Keynote measured the relative performance of the leading voice providers in the New York and San Francisco markets, including digital cable voice services, adapter-based Voice over IP services, and PSTN service in those cities. Keynote then rated the leading voice service providers on critical performance factors that influence the end-user experience using Keynote’s commercially available Voice Perspective®, an on-demand voice quality test and measurement service.
Study Focuses on End-User Experience
The fourth Keynote voice service providers’ competitive research study rates the relative performance of PSTN, PacketCable, and VoIP hard phones in the New York and San Francisco metropolitan areas. It compares VoIP service providers based on reliability and audio clarity over consumer cable modem and DSL network connections and then evaluates network carrier performance on end user perceived call quality. The study evaluates the range of performance between the best voice service providers and the worst. The study also examines variations between prime-time performance and non-prime-time performance of the voice providers and pinpoints the strengths and weaknesses of each service provider and the voice service technology.
“As VoIP continues to make inroads into business and residential users, customers expect no less than a “toll quality” voice call. In order to achieve that, service providers will have to continuously monitor the quality of the calls and examine and isolate bottlenecks before they affect customers,” said Rajeev Kutty, VoIP product manager at Keynote.
How the Study Was Conducted
The Keynote Voice Competitive Research Study was conducted using Keynote's commercially-available Voice Perspective service to evaluate critical performance factors that affect the consumer's experience with telephone service.
Keynote placed local and long distance VoIP calls to destination phone numbers on standard (PSTN) phone service. Calls were placed from San Francisco and New York once every 30 minutes for each voice provider and network carrier combination. A total of 125,000 calls were placed over a month-long period. Test calls were compared to traditional phone "toll quality" standards to determine what residential customers can expect when switching from traditional phone lines to VoIP.
To reflect the very latest trends in VoIP technology, the new study implements updated voice quality test and measurement methodologies and protocols. This captures more comprehensive and granular data and strengthens Keynote’s ability to assess overall VoIP quality. The result is an accurate representation of the current state of VoIP service quality as perceived by the average consumer of a VoIP service provider.
