This paper evaluates if the Internet can support enterprise-grade audio conferencing. For our investigation, we collect real-world traffic traces from the audio conferencing solution in GoToMeeting, a popular online meeting application. We analyze these traces using Conference MOS, a new metric proposed in this paper to measure the quality of an audio conference. Our results indicate that a majority of users experience good conference quality. A small percentage of users that experience poor quality because of high delay and loss would be better served with PSTN. This leads us to believe that an enterprise-grade solution should adopt a combined VoIP and PSTN deployment strategy over a VoIP only solution.
