Hi,

Any suggestions would be welcome with the following scenario:

External app managing calls trough ESL
We have to detect inband DTMF digits (we generally try to use a configuration where we don't have to deal with inband DTMF digits, but in some rare cases it cannot be avoided). There are cases when a playback has to be stopped when a certain digit is received. Inband DTMFs are detected with spandsp_start_dtmf. So the following happens:
  1. Inbound call answered
  2. spandsp_start_dtmf called 
  3. A file is being played
  4. Client starts to send an inband DTMF
  5. After a very short time FreeSwitch issues the DTMF event
  6. External app stops the playback with uuid_break
  7. External app starts to play a different file
  8. Freeswitch detects the same digit again (which is still present in the RTP, the DTMF is on for roughly 400ms, and only ~190ms has elapsed since step 5)
The scenario is reproducible and happens in a consistent way. The inband DTMF is continuous. FreeSwitch reports only 1 DTMF event if the play is not interrupted with uuid_break. 

Is it possible to avoid this sort of multiple detection? Or do I have to handle this in the external app level?

Is this an issue I should report to JIRA?
