Inband DTMF detection on Asterisk 1.2 broken
Tony Mountifield recently found out that the inband detection of DTMF in Asterisk 1.2 was broken when the tones were not perfect. Check the bug report here. Because Asterisk 1.2 is in security maintenance mode only, Tony’s fix will not be committed to the Asterisk 1.2 code tree. Either get the patch from the bugreport or if you are on an RPM based system get the upcoming respin of the RPMs at http://www.laimbock.com/asterisk/.
