As Alexander mentioned there has to be a specific handler for each codec 
in order to parse/store/create the specific attributes internally. It's 
not done for every codec. Asterisk also has to be aware of the codec. 
This is a bit easier in 13+, but may be possible in earlier versions 
depending on the amount of storage required.
