What codecs does Cisco Customer Response Applications (CRA) support?

A. These codecs are supported by the associated CRA version: • CRA 2.2.x only supports G.711 u-law. • Customer Response Solution (CRS) releases up to and including 3.0(2) support G.711 encoding only (a-law and u-law). • CRS release 3.1(x) also supports G.729 Annex A (G.729A) encoding. • Any CRS 3.1(x) system can have either G.711 or G.729 Annex A (G.729A), but not both. • Any CRS 3.1(x) system installed that wishes to change to the other encoding must perform a reinstall of the entire system. • Automatic Speech Recognition (ASR)/Text-to-Speech (TTS) does not work with G.729 Annex A (G.729A) codec. The G.729 Annex A (G.729A) and ASR/TTS are mutually exclusive.
