A conferencing method not requiring additional or dedicated hardware in a processor controlled telephone terminal, nor requiring an external conference bridge, is provided by one of the terminals designating the conference, processing signals from two other conferees and delaying only two of the conferees active talkers at any given time. The two active conferees do not receive their own signal. An active conferee remains declared active during a dynamic hangover time, which varies between a minimum and a maximum corresponding to the activity time of the conferee.
