But what if I want to force a specific codec?

Ultimately, what I'm trying to do is prevent FreeSWITCH from transcoding 
on the fly. I would like to have prompts and menus pre-encoded in all 
the codecs I expect to be using with my various endpoints and devices.

That script is just a really stupid test that I'll never use for 
anything. I was trying to make SOX create a .G722 file, but it was 
playing back all garbled, much like my GSM experience earlier in the 
week. This script is an attempt to force FreeSWITCH to record in a 
specific codec to determine if the problem was with SOX and the other 
G722 encoder I tried.

I may be trying to do something that really isn't necessary, but it 
seems like you should be able to do it.
