[Freeswitch-users] The application "hash"

I was trying to explore the documentation for the application "hash" which is in the default dialplan. Its vaguely obvious what its doing, but I wanted to be sure. It appears to be listed as a application under dp_tools, but when I click on it I get taken to a page that talks about limit_hash rather than hash. Is there any documentation for this? Am I looking in the wring place? -- Alan Chandler http://www.chandlerfamily.org.uk
