The first step is to find a conference call provider. Once you have signed up for a conference call provider, they will provide you with all of the things that you need in order to quickly and easily arrange a conference call, whether it is for 3 or 300 participants. Testing the bridge line before initiating the call is highly recommended. This will also allow you to get familiar with the way that the conference call system works.
Making the call from a quiet location with minimal background noise will allow you and other participants to focus on the subject matter at hand rather than being distracted by outside noise. As the host, it is best that you be the first on the call, that way everyone else may dial in without having to wait but it shouldn't be required. Some conference call services, including ours, will let you to join early or late without issue.
