<div dir="ltr">After looking very close at the output from my working and non-working log files, I believe this might be a side affect of something not directly ZRTP related. I have noticed that in my older working servers, I see " Auto Changing port from" twice. My freeswitch is not behind a NAT, but clearly my clients all are. In the latest pull, I only see this line once. <div>
<br></div><div>Going off the assumption that it isn't correctly translating the two clients connections, I tried a build where both the FS and the clients are all directly accessible with neither side behind any NAT. After doing this, my clients negotiate ZRTP with the same config I have been using.</div>
<div><br></div><div>Perhaps I should start a different subjet with a more precise problem statment, or can someone shine some light on this for me?</div><div><br></div><div><br></div></div><div class="gmail_extra"><br><br>

<div dir="ltr">I have been using freeswitch with ZRTP successfully, and recently decided to do a pull from master. We haven't updated in a while, and I am testing how our current configurations work with the latest git pull. After the pull, my clients can't seem to establish a ZRTP session. Should I be doing this differently, or is there a new variable I need to be setting? I was under the impression that proxy_media would pass the media through unaltered, so I am a bit confused as to why this would change between versions.<div>
