1. A conferencing apparatus comprising:

  • means for receiving signals at a conference bridge from a plurality of input communication paths of which at least two are associated with low bit rate voice signals;

    means for estimating the signal energy in each of said input communication paths to give a signal energy estimation;

    means for comparing each of said signal energy estimations against a predetermined threshold; and

    means responsive to said signal energy estimating and comparing means for decoding only each of said low bit rate voice signals that is required by said conferencing apparatus, wherein said low bit rate voice signals required by said conferencing apparatus is a maximum of (n+1) for a conferencing apparatus in which a transmission on an output communication path utilizes only n signals with the greatest estimations of signal energy other than the signal energy of an input signal associated with said output communication path.
