you should use latest code, at least 1.4.13 or 1.4 svn branch, before reporting issues like this...

I can't use latest versions, because of ASTERISK-1086923. I reviewed the changelog, and there seems nothing fixed in chanspy since 1.4.8. As those issues are rare - i cannot reproduce them on testing server.

If somebody have fixed something that might affect it - please - comment and give me link to related patches.

Please give the branch located at http://svn.digium.com/svn/asterisk/team/file/audiohooks-1.4 a try and report back. Thanks!
