      I recommend only using https on the public internet.

      Now even tough I say that, there are potential problems with this on some devices.

      /me glares at Yealink T4XG series devices

      FreePBX's default Let's Encrypt certificate process on FreePBX 14 creates a Let's Encrypt certificate that Yealink T4XG series phones refuse to talk to. The exact same phone talking to FreePBX 13 with a LE cert generated by FreePBX works just fine.

      So you have to decide to get some other certificate or use take the risk of using http for you device communication. I continue to hpe the Yealink will release a firmware update for this, but it is unlikely as that series of phones are no longer sold. They do not seem to consider them EoL yet, but they were replaced by the T4XS line.

        @JaredBusch Yep. tftp is not optimal for security reasons. Nevertheless, it actually does not seem to work in a hosted freepbx environment and I can't figure out (yet) why. I've turned off the IPFW (yes, I know...this is a test box). I've set the xinet service tftp to verbose logging and tracked the activity. The tftp client successfully talks with the server, requests files, but eventually times out with no data transmitted). I've set my local firewall wide open for the IP address. I'm able to tftp locally from another known good remote tftp server. I've checked the freepbx forums (there are similar complaints about tftp, but those are not on a hosted server and tend to be user error). Was hoping you had run across this issue and made it work (even though it's not recommended). Thanks for your feedback.

          Hi,

          Did you also notice that v14 is super slow compared to v13 ?

            It assuredly is not. I use it daily. I do not use 13 daily any more, but when I did have active clients on both versions, I never had noticeably different speeds in the GUI.

              We still have one client that won't upgrade (they make lots of excuses) and we don't notice a difference either.

                You sure Vultr firewall isn't blocking TFTP?

                  Vultr doesn't have a firewall unless you make one.
                  I mean it is possible they could. Let me test.

                    Lots of people put one in by default and don't even think about it.

                      My setup with FreePBX 14 on Vultr.

                      1. There is no firewall on Vultr blocking anything.
                      2. My home network is marked trusted in the FreePBX responsive firewall.
                      3. The tftp protocal is allowed in the FreePBX firewall to local connections.

                      I can connect to from my desktop with tftp but I cannot download anything.

                          Don't know and don't honestly care. As I said before. Don't use TFTP on the public internet.

                            I wonder if TFTP default bindings are LAN only.

                              It let me connect.

                              Note: it also does not work on my ZeroTier address.

                                  Exactly my problem. But I concluded the same thing. Who cares? I do have a small reason to care, but I've got a workaround and moved on to other topics. Thanks for your 2 cents! Glad it wasn't just me.

                                    I like Vultr's stat page.
                                    Here is the network usage of a PBX with ~80 extensions (all pjsip, if that matters) and 15 simultaneous calls at peak.

                                    What is the specs of your vultr instance with that usage, ~80 extensions and 15 simultaneous calls at peak.

                                    Also, do you have some formula on how to decide what to get instance base on extension and simultaneous calls ?

                                      Bottom line is that the $5 instance is as small as you can go. You need the 1GB of RAM. If they offered a 900MB option, sure that might work. But the 512MB option will not. So you can't go smaller than the $5 option on the low end, don't try. You'll be swapping and things will get bad, fast, if it will even run.

                                      That said, you could handle hundreds of extensions and way more than 15 calls on that $5 1 vCPU / 1GB RAM option. We use that and we do closer to 30 simultaneous and it doesn't break a sweat. And we don't use g711 either, so we are working it harder than normal users.

                                      You would need a LOT of calls or special usage to make you need a larger VM. We have no customers going larger based on RAM or CPU needs, only on storage needs (we have customers doing huge amount of call recordings or voicemails and just need more space.)

                                        Actually 722 doens't use anything in resources jsut like 711. It is all about being on the same codec for the entire call path.

                                          Also, you can scale an instance to a larger plan if needed.

                                            And we don't use g711 either, so we are working it harder than normal users.

                                            Actually 722 doens't use anything in resources jsut like 711. It is all about being on the same codec for the entire call path.

                                            If you have it on the full path and don't transcode. We don't. We have Opus where we can and G722 where we can't, so we are transcoding regularly.
