I'm working on a pause/resume widget. Is it possible to insert a prerecorded audio clip (which would say, "Recording paused") into the recording whenever the user pauses the recording?
This would not be possible with MediaSense. The recorder is actually not in the media path of the actual call. We are getting a copy of the media by the forking device.
The pause and resume is used in the recorder to ignore the data coming in. We do not control the actual data.
You might be able to do what you want by using JTAPI request. In that case, you are pausing the recording similar to what happens when you hit the button on the phone to pause. The CUCM will play hold music which you can possibly set to the prompt you want.
