Hello,
I have created an external VXML 2.0 application that is called from a UCCX script. The applications sends a record request to UCCX 11.6 using a 29xx voice gateway. I wish the recorded audio to be returned to my web server for further processing.
The VXML record request is as follows
<form id="record">
<property name="timeout" value="22s" />
<record name="media"
maxtime="6s"
finalsilence="800ms"
dtmfterm="true"
beep="false"
type="audio/x-wav">
What I am seeing is the request is processed without exception however the audio file is empty. I have limited access to the UCCX platform but what I am seeing is that the following error is being thrown:

Is what I am trying possible? If so is the issue on the UCCX side?
I have seen the following thread Link for incorrect format. I have raised this with the UCCX engineer and they have confirmed that they have it correctly set up from their side.
