[Freeswitch-users] DTMF Problems

[Madovsky]

If you played old arcade games, so my record of type as fast as possible
2 times the same key was 9ms...maybe consider a double under 20ms ? :)

  Will you disclose to the community your optimal time interval for which it is safe to consider the succeeding DTMF entry a duplicate? ;-)

    Well guys it depends on your application , generally  i solve this with regexp , a buffer and a way to clear the buffer of invalid/duplicated data I'm extending it to support with min delay between keys.
    This is not as hard as you think when using min/max :) and your data is predictable :)

    Also in ivr menus humans don't generally guess whats the next menu so if len(dtmf) > 1: drop ... 

    I play with this in our test environment not in our production and it works :)

      Yes, how do you plan the difference between the user dialling 2 and it being duplicated and them pressing 2 twice in quick succession?

        Btw, how do u handle duplicates? Short time interval? If so, how short?

          Yes but i can deal with duplicated digits since the scripts will detected double digits :)
          Let's say i can survive with that :)

            "use RFC2833 and in band at the same time trying to catch any missing tones"


            That's likely to cause you even more problems (duplicate digits).
