A method is for managing connections on a conference bridge. The method includes determining a first noise level associated with a connection between a conference port and a conference server while there is no substantial contribution to the first noise level by a participant's device, determining a second noise level associated with a connection between the participant's device and the conference port while there is no substantial contribution to the second noise level by the participant's device, and determining whether the participant's device should be allowed to be connected to the conference bridge or whether at least one corrective action should be performed based on at least one of the first and second noise levels. Corresponding computer-readable mediums and systems are disclosed.
