Hi, experimenting with BackgroundDetect the module never cancels
playback when entering extensions. Looking at the code, in
app_backgrounddetect.c it looks like longdtmf should be initialized to 0
instead of 1 for any of the logic to work, and setting it to 0 seems to
fix the problem from my tests. Am I missing something? This is in
changeset 5346 but the module code is identical to 1.2.0.1
In this example I dial 930 then hit 1 a few times with pauses between,
then # which ceases playback. rtp detects the digits but they are not
matched by the module. With longdtmf initialized to 0 it works and
playback ceases the instant I hit 1:
