From a7c6c47e61440ce52eef5ecb6f3134e276ddd629 Mon Sep 17 00:00:00 2001 From: Joshua Colp Date: Fri, 2 Nov 2007 20:22:40 +0000 Subject: [PATCH] Merged revisions 88328 via svnmerge from https://origsvn.digium.com/svn/asterisk/branches/1.4 ........ r88328 | file | 2007-11-02 17:20:21 -0300 (Fri, 02 Nov 2007) | 6 lines 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.
