Hello,

I have a script which has four questions to be answered 1 or 0 via DTMF input. If someone doesn’t answer the question I want to set a default answer so I have set four channel variables as follows:

ANSWER1
ANSWER2
ANSWER3
ANSWER4

I have also set a global variable which contains the default answer:

ANSWERDEFAULT = 1

If I use the variable set function to set each of the channel variable to ANSWERDEFAULT before prompting using the Read DTMF function I had expected that if there is no answer to the questions and they time out that in the above example each answer would end up as “1”. However the ANSWER1-4 variables appear to be undefined and so don’t get saved back to the database.

Am I doing something wrong here or have I misunderstood how Read DTMF works? If I actually respond to the questions all of the answers get saved correctly to the database.

Thanks,

Lee

Lee,

If the ‘timeout’ is reached before the caller enters any digits, the ANSWER 1-4 variables will be undefined (empty string).
To handle this situation I would probably go with GotoIf block and expression like: $”${ANSWER1}” = “””” and then branch the call flow based on the expression result.
In case the result is true I would set ANSWER1 = ANSWERDEFAULT.

I hope this helps.
