Hi, I have searched Google and the mailing list archive extensively, but haven't found useful results. We have the following setup: - client A behind firewall - client B behind other firewall - Asterisk directly accessible A and B both register with Asterisk. Now when calling, A and B will try to send RTP packets directly to each other. For various reasons, we cannot use that feature and we want to always use the Asterisk server as an RTP relay. How do we need to set up the account and/or the call for that? Thanks, Florian
