Dear Sir,

Client has provided us recordings in CCITT u-Law 8.000 kHz, 8 Bit, Mono with bit rate of 64kbps format. But when we use them in Avaya DD it doesn't recorgnize file. Per documents DD expects file in CCITT u-Law 8.000 kHz, 8 Bit, Mono with bit rate of 64kbps format.

I am attaching one of file sent by client. Can we know what is that in attached file which is creating issue.

I created a simple application and use the phrase and it played in simulation. Is your problem on the platform?

According to the VXML specification the following audio is supported:

Appendix E — Audio File Formats

VoiceXML requires that a platform support the playing and recording audio formats specified below.

Table 65: Audio Formats Which Platforms Must Support
Audio Format Media Type
Raw (headerless) 8kHz 8-bit mono mu-law [PCM] single channel. (G.711) audio/basic (from [RFC1521])
Raw (headerless) 8kHz 8 bit mono A-law [PCM] single channel. (G.711) audio/x-alaw-basic
WAV (RIFF header) 8kHz 8-bit mono mu-law [PCM] single channel. audio/x-wav
WAV (RIFF header) 8kHz 8-bit mono A-law [PCM] single channel. audio/x-wav
The 'audio/basic' mime type is commonly used with the 'au' header format as well as the headerless 8-bit 8Khz mu-law format. If this mime type is specified for recording, the mu-law format must be used. For playback with the 'audio/basic' mime type, platforms must support the mu-law format and may support the 'au' format.
