2016年1月21日 · What command can I use to show the current port range? It should be the default setting right now in the range of 16384 to 32768. Sorry for the junior questions but my understanding is that each side specify the source UDP port it will use for the RTP stream correct? On my CME even I specify the new port range, it will be my source.
