Asterisk Voice Prompts

Hi, can anyone tell me if there is a reference book is available for asterisk native voice prompts English and their corresponding meanings ??, thank you for any helpful suggestion

I believe the list of message wordings is include with the sounds. In any case it is not too difficult to find on the web, although sufficiently time consuming that I will not do it now.

I doubt there is any more information on the meanings than the wordings themselves, and, in the case of those built into the source code, the source code itself. Many are there for convenience, and are only used if a user explicitly invokes them.
