When i try to detect dtmf answers with playAndGetDigits, it behaves weird. For instance i’m accepting 3 - 4 digits, when i press 42 it plays error sound as usual, but after then when i press 4256, it continues to play error sound.

When i checked detected tones i get strange results. Sometimes it detects 4256 as 426 or 456 with skipping digits. Sometimes it merges with failed digits like 12425

what can be possibly cause this. I couldn’t find any solution.

My related python script codes are below.

gather_result = session.playAndGetDigits(

    int(min_digits),

    int(max_digits),

    int(max_attempts)

    gather_timeout,

    "#",

    ask_sound,

    error_sound,

    "\\d+"

    )

if gather_result:

    session.setVariable(variable_name), gather_result)

    session_vars_list.append(variable_name + "=" + session.getVariable("appvar_"+str(arguments["variable_name"])))

Regards.
