Easy Tips for Hosting Large Audio Conference Calls

Large virtual meetings can be full of distractions, which impact the effectiveness of conference calls and ultimately your company’s bottom line. In a 2015 study, one-third of employees reported a moderate to major negative impact on productivity due to in-call distractions such as background noise and late-joiners.

Perhaps even more concerning, another study found that distracted behavior seems to be par for the course in meetings: a sizeable 91% of attendants admitted to daydreaming during meetings, 73% did other work, and even 39% of participants admitted sleeping during their meetings!

The key to minimizing distractions and running successful large group audio conferences is to be prepared and set a tone of professionalism from the very start. Use these nine easy tips for large conference calls to make your meetings more productive:

1. Create an agenda and stick to it

According to a 2019 study, 68% of respondents report losing time due to poor organization in meetings. But did you know that an average of 63% of meetings are conducted without even using an agenda? When nobody knows what is supposed to be covered on the call, or who is supposed to speak to which topics, you’ve created a recipe for confusion, unproductiveness, and time wasted.

Over half of group conference calls are inefficient because they lack an agenda

Make sure you create an agenda to keep discussions on-topic and on-time. Consider creating a conference call template that gives a breakdown of topics and who will be presenting at that time. Be sure to leave room for adjustments, and schedule time at the end of the call for any comments or questions.

2. Provide a local dial-in number without PINs

When setting up an international conference call, use a local dial-in so participants can avoid paying long-distance group conference calling fees when joining the meeting. Providing a phone number that is local and familiar to your call participants will also reduce the confusion associated with having to type international phone codes, where applicable. Finally, consider using a PIN-free dial-in so you don’t have to worry about participants entering the meeting late because they entered the wrong PIN.

3. Send out detailed instructions

Send out a meeting invite with clear and detailed instructions for how to join the call, including all applicable dial-ins, access codes, and PINs. Oh, and don’t forget the screen-sharing links!

Screensharing inefficiencies can waste over an hour of time if you’re in three meetings per week

On average, 33% of participants say they spend more than five minutes trying to get screen sharing up and running. If you’re on a 30-minute call, you’re wasting one-sixth of your time on a task that should be fairly simple to accomplish. By sending everyone the screen-share link and all other applicable dial-in items ahead of time, your large virtual meetings will run more efficiently.

4. Send out a reminder shortly before the meeting

When hosting large group audio conference calls, chances are several people will lose track of their invites. Be sure to send out another reminder 5 to 10 minutes before the call with the original invite information to get people ramped up and ready to go.

5. Start your large virtual meeting on time

Start your meetings promptly. This will help set the tone for the meeting and help you stick to your conference call agenda. While the average conference call is 38 minutes long, 15 minutes are typically lost getting started and dealing with interruptions. That’s nearly half of your time spent dealing with the negative impacts of late meeting joiners!

Feel free to allow a few stragglers to join in the first few minutes, but make sure they are muted upon arrival. After five minutes have passed, you might consider locking out latecomers to cut down on distractions, and then allowing them into the meeting when there’s a break in the conversation. Remember, allowing people to join late can encourage future tardiness, and if you’re hosting a large audio conference call, all that time lost adds up. 

6. Allow time for introductions

Not only is it a good ice breaker for large meetings, but introducing speakers allows all participants to know who’s leading each portion of the event. Keep introductions short so the you can stick to the agenda and keep things moving along. Have each speaker state their name, role, and a memorable fact about themselves.

7. Use the right tools for managing large audio conference calls

Invest in tools for large group audio conference calls that can help you manage your meetings more effectively. You’ll want to have the ability to:

8. Keep comments brief and to the point

Meetings are notorious for running overtime. Try to keep your comments on-topic and encourage others to do the same, but make sure not to interrupt or talk over anyone. Do encourage comments but agree to address lengthier conversations outside of the call.

9. Record your meetings

Remembering details from a large conference call can be challenging. Just trying to keep up with a conversation in a large virtual meeting is a feat in itself! Add to that the possibility for distractions, and you have at least a few participants who aren’t going to remember anything from your call. In fact, according to a 2008 study, it takes an average of 23 minutes and 15 seconds to refocus after a distraction. If you’re holding a 30-minute call, just one distraction can derail an entire group’s focus for a majority of the call.

While distractions may be impossible to avoid at times, recording your large audio conference calls is a sure-fire way to retain an accurate account of what was discussed. Use your recording to draft a detailed follow-up email with a summary of the discussion and next steps. You can also opt to send out a direct link to the call recording for participants or team members for review.

Tips If You’re Hosting Your First Audio Conference

If you’re hosting your first large group audio conference call, use these additional conference call tips for beginners to take charge and get the most out of your meeting:    

  1. Check your equipment and be familiar with your tools. Surprise technical issues are bound to happen, but you can minimize their effects by taking precautionary steps. Prior to the call, check your wi-fi connectivity and do a test run of your microphone. Know how to use all of your conferencing tools before the meeting starts to ensure the presentation goes smoothly.
  1. Set conference call etiquette guidelines right away. While you’re creating your conference call agenda, also create a set of conference call etiquette guidelines to send out prior to the call. A few etiquette items you might want to call out for your participants include:
  1. Do a walk-through of the meeting if you have multiple speakers. This allows the call to be executed smoothly from beginning to end. The walk-through should cover who is saying what and when they will be speaking. You can then avoid speakers stumbling to unmute themselves or forgetting it’s their turn to talk.
