Conference bridge with improved handling of control signaling during an ongoing conference

摘要

In an exemplary method audible signals from participants of a conference call during the ongoing conference call are processed by a conference bridge. An incoming audible signal on a first line from a first participant is detected during the conference call with a plurality of other conference call participants coupled via corresponding other lines. The audible signal on the first line is automatically attenuated before information on the first line is summed into a common signal that is transmitted to the other conference call participants. This prevents the other participants from hearing the audible signal during the ongoing conference call.
