You can't. With SIP as the channel technology, at least, the SDP 
negotiation model demands a uniform codec from both sides.

I guess there's nothing to stop two endpoints that both have multi-codec 
capabilities from using different codecs for send and receive in 
*principle*, but it would fall outside the standard implementational 
behaviour of SIP endpoints.
