Hi, I looked at the archieve and tried to find a solution for natted clients in a carrier environment. I have to say I am clear as mud. In our senario, some clients are behind nat, while others are not. Clients may move between nat and no-nat. What's the best approach to rtpproxy/mediaproxy. In rtpproxy's readme, it uses "search" to find certain client. It has issues to support other clients. Is nat_uac_test/client_nat_test sufficient to test either src or dest is behind nat and should go through media proxy? What if some clients have stun support? What if some are behind symmetric NAT and some are not? Thanks for your help. Richard __________________________________ Do you Yahoo!? Yahoo!
