This is awesome thanks so much for the detailed reply this is a huge help. I didn't notice I could prioritize the RTP so that's good. What is a normal range to have open if all that would ever happen is 5-6 concurrent calls?
At least four times the number of concurrent calls, but leave room for more in case Asterisk doesn't free up the ports immediately. I'd probably set it to 50 or 100, but not the default of 10000. »www.voip-info.org/wiki/view/Aste···rtp.conf
