Abstract: A system for tunneling wideband telephony, comprises a communication device configured to produce a compressed wideband audio signal. The compressed wideband audio signal has (i) an audio frequency passband greater than that of an 8 kHz sampled audio signal, and (ii) a compressed data rate that is less than or equal to 64 kbps. The system also includes an apparatus, such as a voice gateway, coupled to the communication device and a data link, including a transcoder bypass configured to convert, without transcoding, the compressed wideband audio signal into a data stream including wideband compressed audio data for transmission over the data link.
