[Freeswitch-users] Handling DTMF noinput and nomatch

[Boris Kovalenko]

Hello!

     And what is the problem to check length of dtmf_digits variable? 
This is string variable, so You may use dtmf_digits.length .

>         session.flushDigits();
>         session.speak("flite", "kal", 'please enter your 4 digit pin', on_dtmf);
>         dtmf_digits = session.getDigits(4, "", 5000, 1000, 10000);
>         console_log("pin=" + dtmf_digits + "\n");
>     }
