Yes you are right , but in my scenario a couple of Asterisk behind NAT  must not route RTP directly , all must go to RTP Proxy  so i have found that case that for me its not working.

Sorry if i haven explained so much.. 

If i turn STUN off as Olle mentioned, all worked fine.. but if i have a customer that for error it turns ON it does not work in my case.. 

Any way to force RTP in that cases?

Isn't that the point of using things like STUN?
