ABSTRACT:
An apparatus for converting voice packets transmitted/received through a network includes a first transcoder for performing at least one of bit-unpacking and unquantization on an encoded packet at a first encoder, namely transmitting party, to obtain an LSP (Line Spectrum Pair) parameter of the first encoder, and converting and unquantizing the LSP parameter to an LSP parameter of a second encoder, namely receiving party, to do bit-packing. A second transcoder performs at least one of bit-unpacking and unquantization on an encoded packet at the second encoder, namely transmitting party, to obtain an LSP parameter of the second encoder, and converts and unquantizes the LSP parameter to an LSP parameter of the first encoder, namely receiving party, to do bit-packing.
