 An audio conferencing provider is a third-party company that provides organizations with conferencing services.
 Among other things, audio conferencing providers provide a way for users located off site, and not connected to the corporate network or the Internet, to participate in the audio portion of a conference or meeting.
 Audio conferencing providers often provide high-end services such as live translation, transcription, and live per-conference operator assistance.
