[SVN commits to the Asterisk project]

Author: rmudgett

New Revision: 304005

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=304005
Log:
DTMF attended transfers sometimes fail for no apparent reason.

The loop in feature_request_and_dial() can exit when Party C has answered
without processing an AST_CONTROL_ANSWER.  Also sometimes an
AST_CONTROL_ANSWER never happens even though Party C has answered.

Don't hangup Party C if he is up or we receive an AST_CONTROL_ANSWER.
