it's not true way im my mind, there is another protocol endpoints, for example iax,
if call scheme like h323->fs->iax i need 2 differen converter one to sip sdp and one
to iax? i think clearer way to pass codecs to some kind of global var for a call, 
and each ebdpoints module will take it from there and konvert in his own format 
himself, any other ideas?
