To identify the source of echoes:

• Ask if there is anyone on the call who does not hear the echoes. The participant who can't hear the audio problem is usually the source of it.
• Have the moderator press *96, then option 1. Then roll-call participants one by one, asking each participant to un-mute their line (*6) and say their name.

Once identified, advise the participant to press *6 to mute their line or disconnect and dial in again.

Note: Some line echoes may be caused by a participant telephone or speakerphone set at high volume. Lowering telephone volume may reduce these echoes. If your phone does not have a volume control, use the star control *8 to lower your volume. To see all star controls, see How To: Use All Star Controls.
