since couple of version, the stun implementation is a module:
When the client side uses stun and turn, kamailio should not do anything
special, just forward requests.
Probably other dedicated stun server projects are more up to date and
complete implementations, if the implementation in kamailio is not
sufficient, you can use them just fine, not problem from kamailio point
