A system and method for reducing or eliminating degradation in voice transmission quality resulting from repeated or sequential compression and decompression of voice packets over one or more packet networks. When a voice connection is established between two parties on separate packet networks, the signal is often passed through a PBX and/or over PSTN lines, with the occurrence of two tandem low-bit-rate codecs used to transfer the signal and introducing degradation of voice quality. This situation arises frequently in voice-over-packet applications. The situation can also arise when a call is forwarded from one place to another. The present invention reduces the degradation associated with the transport of voice data and thereby improving the voice quality by removing one of the tandem codecs.
