Good afternoon! During a conference call today the other participants were experiencing echo coming from our end. An IT person on the other end said that it seemed like we had 2 mic sources going which was causing the interference. We also noticed the echo and it was hard to communicate with the users who were all signed into a Zoom VC. In the end we had to reschedule for a later date. My question is, is there a setting on the device itself that we should be aware of that will negate an echo? Is there something else in the room that would cause interference? Is there a troubleshooting guide for this problem? Could it have been a problem on the other end? Thanks!
