I've tried the new NATMediaproxy.cfg, but I still have the same problem. I cannot make calls from the pstn-to-sip. I get only one way audio, in the direction sip->pstn, but just the UA sends rtp traffic to the gateway directly. The proxy is not talking with the UA. thanx lucas We had found that the config files provided didn't work as expected, so we now have tested the mediaproxy version and modified it to ensure that is works. We have also updated the rtpproxy file to reflect these changes. So please download the new version 03a which we hope now works ! ! www.ONsip.org Sorry for the inconvenience but this is why we are a community working together.
