San Mateo, Calif. - While the reliability of Internet telephone services has generally improved over the past several months, the major providers still have plenty of room to improve in terms of audio clarity, according to a new study by Keynote Systems. The firm measured 11 service providers on several performance factors. Though the top providers had improved the quality of their call audio since Keynote's initial study in June, the firm said that it found no significant change in the amount of audio delay present in the calls -- a factor that it said "can lead to conversational disruption." Keynote, in fact, said that Internet phones continue to have up to twice as much audio delay as calls placed on traditional phones. Time Warner Digital Phone ranked first in both reliability and audio clarity in the studies conducted in November and December, edging out Vonage and AT&T CallVantage.
