I'm using JSSIP, and there is only one place where they call stop() on the MediaStream (in RTCMediaHandler, for those curious), which I removed. In our code interacting with JSSIP we also do not call stop(). This is why I believe somewhere in the Peer Connection code (or maybe the default MediaStream listeners) there is a stop() call or something to that effect which I cannot reach. _______________________________________________ dev-media mailing list [email protected] https://lists.mozilla.org/listinfo/dev-media
