Have some notes handy to initiate small talk at the beginning of the call. Introduce all attendees by their names, titles, and roles they play. If anyone arrives or joins the call after the five-minute delay, don't interrupt a discussion in progress. Wait until after a speaker has finished or a topic has ended to allow latecomers to introduce themselves. Ask attendees dialing in to mute their phones to avoid background noise. Request that they avoid using the hold button to prevent broadcasting their company's hold music. Tell everyone physically present to silence their cell phones and keep them away from the meeting phone to prevent interference. Make sure all attendees speak audibly and clearly so that everyone can hear them. Keep an eye on the clock to accommodate the needs of attendees and presenters.  Cover the most important issues first in case you run out of time. If anyone asks a question you can't answer or weren't expecting, tell them you'll get back to them as soon as possible. Don't wait until the end of the call to do this. Do it right before you get to questions and answers (Q&A) on the agenda. Ask everyone the most convenient date and time for the next call. If most attendees are undecided, send out a scheduling survey after the call. In a conference call, you might have trouble getting everyone to participate. To prevent this from happening, don't ask if anyone has any questions. Rather, ask specific people relevant to the topic of discussion a question. For example, you could ask, “Bob, have you gotten all of the information you need to create the topic text?” Start to wrap up about five minutes before the scheduled ending time. If Q&A is still in progress, tell everyone you have time for one more question. Thank everyone for their time and wish them a good day or week(end).
