New Revision: 88328

URL: http://svn.digium.com/view/asterisk?view=rev&rev=88328
Log:
If an INFO request within a dialog is received with a content length of 0 simply send back a 200 OK. It is valid to do this and the remote side is probably using it to make sure the signalling is still alive.
(closes issue #5747)
