Review request for Asterisk Developers.


Changes
-------

Addressed residual issues.


Summary
-------

Document DTMF events for different sequences.

* Fix extra hit required when new DIGIT is sent without any interdigit delay.
* Fix when DTMF_HITS_TO_BEGIN = 2, and no interdigit gap, that BEGIN is posted. 
* Fix situation where a flakey detect, would clear the current_hit (indicating an END), which may not have been the case.


Diffs (updated)
-----

  trunk/main/dsp.c 371689 

Diff: https://reviewboard.asterisk.org/r/2085/diff


Testing
-------

On production box for 24 hours. 888 digit's now received.

The change here doesn't affect normal tone on/tone off, it changes the case when no interdigit pause is received between 2 digits, now the 2 digit has the same detect time as if there had been an interdigit pause before hand.


Thanks,

Alec
