[svn-commits] tringenbach: branch 1.4 r277625 - /branches/1.4/res/res_features.c

New Revision: 277625

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=277625
Log:
Save and restore AST_FLAG_BRIDGE_HANGUP_DONT on attended transfer.

ast_bridge_call() clears AST_FLAG_BRIDGE_HANGUP_DONT. But during an attended
transfer, ast_bridge_call() is called for a second bridge on the same channel,
and it clears that flag, which still needs to get set for when the original
ast_bridge_call() gets control back and checks it.
