New Revision: 407398

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=407398
Log:
Had a great lunch at a thai restaurant and discussed my patch with me, myself and I. Decided that 
it was stupid to work on milliseconds when we simply could count the frames as they pass us by.

I agreed with that decision. No protocol was taken.
