Later I found out that someone caught a power strip with their foot and unplugged the videoconference unit. I hate when that happens. Taming technology After creating your soundstage, you need to have the right equipment to capture your presenter's voice for the call. If your event lasts 90 minutes or less, stick with the telephone handset. Modern business phones produce better quality audio than the phone line is capable of reproducing.
Headsets are an option if the call goes longer.
However, they require more effort to use, and the presenters should be very comfortable using them. Also, make sure you do a pre-event check to make sure that participants have their microphones properly situated. Even then, trouble can occur. Last year, a colleague and I managed a program in which most of the speakers had never used a headset. After a quick lesson, the program was live.
