We dont know what are you talking about, This forum is for plain Asterisk, not GUIs or custom systems, please elaborate in order to get help or try in the Elastix forums.

I’m certain that Asterisk doesn’t produce that message. I’m fairly sure it is not included with either the standard or additional sound files.
