FIELD: communications.
SUBSTANCE: on a VoIP server, the encoded voice signal of each subscriber, received from a data transfer network, is decoded. The volume level of the voice signal of each subscriber is measured. Signals whose volume level exceeds a preset level are summed up, and the obtained sum is encoded and transferred to each subscriber. When transferring the obtained sum to a subscriber, the volume level of the voice signal of which exceeds the preset level, the current subscriber signal is subtracted from the sum.
EFFECT: prevention of amplification of acoustic echo; reduced expenditure.
