WAV File Requirements
Topic Last Modified: 2009-01-23
You can use a .wav file for some Response Group settings, such as the welcome message, the on-hold music, or the Interactive Voice Response questions. All user provided .wav files must meet the following requirements:
- 8-bit or 16-bit file
- Linear pulse code modulation (LPCM), A-Law, or mu-Law format
- Mono or stereo
- 4MB or less
For the best performance, a 16 kHz, mono, 16-bit .wav file is recommended.

Note
The following list contains the exact sampling frequencies required for 11kHz, 22kHz, and 44kHz files (that is, an 11000Hz file is not supported by the system):
- 11kHZ=11025Hz
- 22kHz=22050Hz
- 44kHz=44100Hz
