Twilio Call Duration while call is in progress

spark_sara

I am trying to set a limit on how long a caller can stay on the call with the Ivr. So what i wanted to do was when the user presses a key which sends a http request to my server I would check the 'CallDuration' parameter and if its over a limit then disconnect the call. But then I noticed that the CallDuration is only included in the End call fetch and not in each onkey press request. Any ideas how I can do this? how can I know the call duration...

Great question — answering as the UphillTech team:

I've had to do something similar, I ended up having to store the Call information into a temporary database (DynamoDB) and store the Call invite DateTime. Lets call this inviteDateTime Then anytime there was an event on that particular call, I'd use the CallSID to query my Call Table, calculate the call duration based on the currentTime() - inviteDateTime If the Time Elapsed is over the time I allow, I then use the API to overwrite the Twiml for that call. For example, I'll <Say> a message that we're too busy and to call back, then hangup the call.
