From 49b90d5e61dd158e963cd5d623cbca50e8b4f1c8 Mon Sep 17 00:00:00 2001 From: Richard Mudgett <rmudgett@digium.com> Date: Wed, 7 Oct 2009 21:56:36 +0000 Subject: [PATCH] Merged revisions 222691 via svnmerge from https://origsvn.digium.com/svn/asterisk/branches/1.4 ........ r222691 | rmudgett | 2009-10-07 16:51:24 -0500 (Wed, 07 Oct 2009) | 14 lines chan_misdn.c:process_ast_dsp() memory leak misdn.conf: astdtmf must be set to "yes". With "no", buffer loss does not occur. The translated frame "f2" when passing through ast_dsp_process() is not freed whenever it is not used further in process_ast_dsp(). Then in the end it is never ever freed.
