Plum IVR Support

I'm looking for any hints or pointers to implement the ability to Append to a recording.

Basically, once a recording has been made, I need to give the user the ability to review the recording, and then optionally add to that recording. Naturally, they need to be able to repeat the review and append cycle if necessary.

Is there a way or technique to do this?

You'll need to do this in post processing on the IVR server. Fortunately, with headerless 8 bit u-law pcm files, appending is as simple as concatenating files. Then the concatenated audio file can be played back to the user as a single file.

Before you get back to your IVR application server, you can "append" recorded audio simply by playing recordings in succession with no break between them.
