True, you only need a CODEC if your system is using 
anything other than G729. In that case you would 
only be using pass through. 

Only if you are COding or DECoding do you need a CODEC. 
For G729 SIP phones, or G729 carriers asterisk will 
not do any coding or decoding and you do not need a 
G729 CODEC.

You should be able to, though I couldn't tell you how.
