RE: [Serusers] sems IVR plugin bug??? - sr-users

Great. 

One thing I was thinking is that if most people need this value to be set smaller then
someone
should commit a change to CVS this this at 8 to 10 rather than 20.

Thanks,
Paul

  Hi Java,

 That value is to prevent double detection, i.e. the same key is detected
 twice. Too large, it runs the risk of not detecting the right key. To small,
 it increases the chance of double detection.

 I use 7 or 8 in my system.

 Hi All.

 Perhaps I just fixed this, but will my change cause other problems? The
 change I made was in
 IvrDtmfDetector.h

 I changed

 DTMF_INTERVAL = 20

 to

 DTMF_INTERVAL = 10

 And now dialing DTMF digits is ok. Will reducing DTMF_INTERVAL to 10 cause
 other issues?

 Regards,
 Paul

  Hello All.

 I'm using sems which I updated from berlios CVS tonight (2004-11-04).

 There appears to be a bug in the DTMF detection in the IVR plugin.

 Using the DTMF-detection.pl test script that ships with sems, DTMF  detection works
fine for
  non-repeating digits. However, it always drops a
digit if you repeat a  number.

"in-audio",
  "via RTP", and "via
  SIP
 INFO". The "in-audio" and "via RTP" both produce this problem
while the  "via SIP INFO" digits
  are
 never detected (which is understandable).

 I searched the mailing list but found no reference to this problem.

 So the question is this; Does anyone have a patch to fix this?

 Regards,
 Paul
