<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>
