Most minor Audio Quality issues can be alleviated by following some tips such as:

  • If you’re the Host and you hear that someone is bringing noise into the conference, ask them to mute their own line, by dialling *6

  • Avoid long distance calls into your conference, notify your guests they should use their closest local number as listed at

  • Avoid speakerphones if possible; speakerphones can introduce their own noise and echo. If someone on the call is using a speakerphone, ask them to mute their line when not talking.

  • If speakerphones are unavoidable, make sure the volume is not too high on them as this can cause echo and distortion

  • Avoid typing, rustling papers and heavy breathing. Any of these activities can bring in noise into the conference call. Again, if these activities can’t be avoided, mute the line using your phone’s mute function

Dealing with persistent Audio Quality issues, like echo, feedback or background noise, on your Conference Call can be incredibly frustrating, or worse embarrassing on those critical calls. The causes of these disruptions can be wide ranging, but nearly all of them can be resolved with a couple of simple steps.

  1. Identifying which line on your call is the source of disruption.

  2. Muting the disruptive line.

If you hear hold music on your call you can Identify and Mute any disruptive line(s) by dialling #1.
 After you dial #1 the system will play a message to the call telling them that any noisy lines will be muted. Once the message has ended, the hold music will have been muted.

1. Identifying which line on your call is the source of disruption.

  • You can ask the callers on the conference directly who is bringing in the disruption, for example: “Who is at a train station? Who is typing? Who is eating? etc. In our experience, this can be unreliable as Guests may be slow to acknowledge the disruption they are causing.

  • Using our mobile app, you can view your callers and easily identify who is making noise and when. This should make it easy to see who is causing unwanted noise on your call.

  • You can pre-empt any disruption by using Active Mute when the call starts, by dialling *5

  • If using Anytime, you can log into MyAdmin and use our Web Console to view and manage callers while they are on the call.

2. Muting the disruptive line.

  • You can ask Guests to mute their own lines by dialling *6. Again, this may be ineffective as Guests may be reluctant to mute themselves.

  • Using our mobile app you can actively mute any disruptive lines through the app’s interface.

  • If using our Web Console, it is simple to select and mute the disruptive line.

If you experience consistent issues which aren’t alleviated by the above, please contact us to arrange some testing. We will need to know:

  • Does this happen on all calls or just with some groups?

  • Does the same happen if you dial in from a different handset/extension (or even a mobile)?

  • Do other callers on the line hear the same?

  • Does the same happen if you dial into a conference via another 247meeting dial-in number (see

  • Has your local IT/System Administration looked into this issue?

If you hear a really loud crackling in your conference, one of the callers dialled the same line into the conference call twice! This causes a loud crackling/static noise which renders the conference unusable until those lines are hung up.

We see this every few months – it’s typically caused by using boardroom speakerphones which can be powered off without actually hanging up a call. When powered up, a second call is placed along the same audio path (line), causing the noise

If this happens (although it is rare) you can do two things:

1: Use the ## command on your keypad (Host hangup) which hangs up all lines and kills the feedback loop.
 2: Contact Customer Service who can hang the lines with the issue up.
