Remove obsolete OLD_DSP_ROUTINES code. Also, remove the FAX_DETECT define and
only do the calculations if fax detection is enabled on the dsp. (closes issue #11331) Reported by: dimas Patches: dsp.patch uploaded by dimas (license 88) git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@89490 65c4cc65-6c06-0410-ace0-fbb531ad65f3
