A. These audio codecs are supported for use with all versions of Cisco Unity: • G.711 u-law and a-law. • G.729 Annex A (G.729A) at 20 ms packetization rate ONLY. Cisco Unity TAPI Service Provider (TSP) 7.0.3 and later supports g.729a from 10 ms up to 60 ms packetization rate. • Intel Dialogic OKI ADPCM 8 kHz. • Intel Dialogic OKI ADPCM 6 kHz. • GSM 6.10. In addition, the G.726 codec is supported for use with a Cisco Unity version 4.0(1) or later system that runs Microsoft Exchange and uses the Voice Profile for Internet Messaging (VPIM) networking option.
