[asterisk-commits] irroot: branch irroot/t38gateway-1.8 r319014 - /team/irroot/t38gateway-1.8/res/

[SVN commits to the Asterisk project]

Author: irroot
Date: Sun May 15 04:04:46 2011
New Revision: 319014

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=319014
Log:
We dont need a T.38 gen as there is no timing dependancy.
Change the default of transmit on idle to FALSE this
needs to be configrable via FAXOPT perhaps.
