Not that I know of. STUN and the like are client-side constructs, 
designed to be used by UACs, which Kamailio is not. A proxy does not 
endogenously originate messages (at least, formally), only receives and 
relays them, so the thinking is that other SIP elements should know how 
to reach the proxy, not that the proxy should be telling them how to 
reach it. Putting Kamailio behind consumer-grade DNAT inverts the 
envisaged client-server model.
