[SVN commits to the Digium repositories]

Author: tzafrir
Date: Tue Mar 18 18:51:15 2008
New Revision: 4012

URL: http://svn.digium.com/view/zaptel?view=rev&rev=4012
Log:
* We need to silence the echo-canceller buffers as well.
* But no need to cancel echo on channels without PCM.
* Switch to FXS hardware DTMF detection again.
