Here are the steps to make reasonably nice sounding CIC (Customer Interaction Center from Interactive Intelligence) or EIC (Enterprise Interaction Center) prompts using Asterisk voicemail and Sox Wrap on OSX. It assumes you have voicemails emailed to you as files with asterisk.
- Make a direct to voicemail call (i.e. dial *200)
- Record the prompt as a voicemail
- Save the voicemail file somewhere once you receive it in email
- Run SoX Wrap, and add the new file as an input file, auto-detecting input settings
- Output settings: .wav, sample rate:8000 Data Encoding: u-Law Data Size: Same as Input Volume 1 Channels 1
- Click Run Sox
- Rename the output file as needed, and copy to the resources directory on CIC.
