      I will say.. I like the Sophos box, but I hate the GUI and how "proprietary" everything feels. It's difficult to navigate and determine how to properly open ports, etc. for this to work. Still no outbound or inbound calling working.

        So made some progress.. If I call OUT now to my cell my cell will see it. There is no ring from the internal phone and once connected there is zero audio. Still cannot call IN.

          OKAY. So.. we are back to the original problem but I have fully migrated the PBX to the newer infrastructure PBX > Sophos UTM > Fiber vs PBX > Linksys router > Comcast Business Modem

          I can call out, I have audio, but I can only call in for a short duration AFTER an outbound call is made.

            @samsmart84 okay, so this confirms shit is just fucked up.

            Ok. The hard part here is making sure you have no outbound calls.

            Then when you make an inbound call monitor the CLI

            asterisk -rvvvvv

            And then call in.

              Check the price difference and see if you still like it 😉

                I get nothing in the CLI for inbound calling when it fails. When I call out first then call in, stuff shows up obviously but not seeing anything that would indicate an issue (as far as I can tell)

                      I really need to just trash the whole thing and start with a setup that's actually modern/supported

                        umm, ok.. /me racks brain cells

                        So first, shut off iptables and see if the problem goes away.

                        service iptables stop

                        Your system if not direct ont he internet right? So this should be safe enough for a short term test.

                            Well that points back to your routing which is the root cause of this circle jerk.

                            Because in 2.8, the only firewalling was iptables.

                            If that is not running, but you are not seeing anything hit the PBX, then it is like the call is not making to it.

                              I am trying to think where else to look, but not getting anywhere.

                                Yeah it's just so odd.. I can't wrap my head around why the SIP trunk IP changing would break inbound. On the old router config there was literally no reference to the actual SIP trunk IP or anything else I could see that would be affecting it

                                    Success! So basically some trial and error with the settings.. I had to turn OFF the Sophos VOIP options as that was actually BLOCKING everything (Go figure). I had made the DNAT rule listed in that link before but didn't have any success - the auto firewall rules with it didn't work evidently. Running the DNAT mixed with creating manual firewall rules for outbound calling and it all seems to be working. I've been testing for about an hour - when I turn the DNAT off it stops working and when it's on it works just fine so I think we've got the right combo at this point.

                                    Thanks for all your help everyone! That was a pain in the butt to track down.

                                      That’s actually expected. That’s SIP-ALG. Always have to disable that. It’s basically just SIP blocking.

                                        Nice of them to include that as a SIP "feature"

                                          It’s so dumb. But every vendor does it. So don’t think too badly of Sophos. Only vendor I know that doesn’t do it is Ubiquiti. And they do it, it just works.

                                            @samsmart84 Maybe this Sophos KB article will help?

                                            Success! So basically some trial and error with the settings.. I had to turn OFF the Sophos VOIP options as that was actually BLOCKING everything (Go figure).

                                            That’s actually expected. That’s SIP-ALG. Always have to disable that. It’s basically just SIP blocking.

                                            Nice of them to include that as a SIP "feature"

                                            It’s so dumb. But every vendor does it. So don’t think too badly of Sophos. Only vendor I know that doesn’t do it is Ubiquiti. And they do it, it just works.

                                            Sorry to disappoint, but it Ubiquiti does not have it disabled by default.
                                            You have to disable it.

                                            configure
set system conntrack modules sip disable
commit;save;exit
