I don't think you can have a single call recording an 'attempt' while you 
record the entire call at the same time. How about recording each attempt 
separately and concatenating after the fact?

I did something similar a few years ago using an AGI with the 'record 
file' AGI command and exec'ing the 'monitor' and 'stopmonitor' 
applications.

At the completion of the call, an AGI executed 'normalize' to adjust 
different caller's 'volume' on the individual files, 'sox' to concatenate 
the files, 'ffmpeg' to encode to WMA (client requirement) and 'curl' to 
upload to the client's web site.

FYI, if you anticipate concatenating more than 32 files, you'll need sox 
14.x instead of sox 12.x included with some distributions.
