My organization holds board meetings periodically. Some cannot make it to our site, so they participate by conference call. For the ones that do make it on-site (which is the majority), we have a speaker phone set up in the middle of the room. We setup a bunch of tables, in a space that is 80ft by 30ft, and we are talking about 30 people.
The problem comes from the people who are listening in remotely. They couldn't hear the people on-site at times. When they could hear, the quality was good at times, poor at others.
Does anyone have any suggestions on what sort of equipment/setup would enhance the audio experience for people calling in?
