      @Skyetel how new is 4.skyetel.com my PBX doesn't see the A record now.

      So my initial test was valid, but seems DNS is not solid yet or something.

        If I remove the 127.0.0.1 it resolves. But I've never noticed issues in the past. with this typical setup.

          Also, since 4.skyetel.com has both A records and SRV records, it works perfectly in FreePBX without any extra firewall settings or the need for the match/permit setting in advanced.

            This was our mistake - we reset our DNS settings for 4.skyetel.com in preparation for tomorrow mornings announcement. Should be solid now that it’s been deployed to our production settings on Cloudflare. (It needed TCP support)

                TLS/SRTP support coming? Or just setting up TCP for those unlucky people that have to use it?

                  Just for those who have to use TCP.

                  TLS/SRTP forces us to get into the audio path and we’re not super excited to do that. Upstream PSTN networks don’t support it either.

                    Not something I'm worried about but there are always those clients that think it is a must have.

                      Asterisk itself supports SRV and has ever since PJSIP was released.

                      I've never bothered to dig into WTF FreePBX is doing with DNS yet, but I cannot use srv.skyetel.com in a PJSIP trunk. I assume because there is no A record. Asterisk recognizes things mostly, but the trunk never comes up for outbound calls. Your portal shows green and I assume I will get calls (never tested that and I should).

                        Well - it looks like we have to issue an update about this.

                        Unfortunately, 4.skyetel.com clashes with some systems that do not support numerical values in DNS entries (yes, thats a real thing) and so please use na.skyetel.com instead. We will be sending out an email tomorrow asking everyone to please use na.skyetel.com instead of 4.skyetel.com. Sorry for the headache guys.
