Use Case:
We have a simple menu built in twiml which asks the language of the user (one of 3 languages possible).
Then we redirect them via Dial and Client to one of our customer support people (most customer support people speak at least 2 languages)
The client is a simple page we have built (with integration in our CRM) based on the twilio client javascript.
Now we want to pass the language so we can display the chosen lannguage to the customer success manager.
I know we have the parameters on the incoming call (https://www.twilio.com/docs/api/client/connection#parameters) but this does not seem to allow us to pass arbitrary parameters. Also in the dial / client twiml verb we see no method to pass extra data.
Is there a possibility to achieve the same behaviour?
