[Freeswitch SVN]

Author: trixter
Date: Thu Jul 12 19:59:51 2007
New Revision: 5531

Added:
   freeswitch/trunk/scripts/contrib/trixter/asyncsock.pl   (contents, props changed)

Log:
coded to bkws specs, captures dtmf in async mode, prints to console, configurable timeouts for dtmf, from first digit in sequence (optional) and from last digit in sequence.  Once a sequence is printed it starts over
