New Revision: 352149

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=352149
Log:
Correctly apply FAXOPT settings (V17, V27, V29) before starting spandsp layer

While the FAXOPT function could be used to set the modem capabilities, the
input to that function was not being applied correctly to the spandsp layer.
This patch applies the current model capabilities before starting the spandsp
layer.
