      Tomorrow I will remove the DMZ and put the Public IP in the PF WAN.

      I will release the RTP and 5060 ports on the LAN with full permission for the IPBX cloud network.

      I will create a static route for this network and activate (Static route filtering - Bypass firewall rules for traffic on the same interface).

      Any other tips? NAT output type or something else?

        Obrigado pela ajuda.
        Também temos configurações básicas no nosso sistema, por isso nunca tive que lidar com o VOIP, que está num ambiente DMZ e / ou dual-NAT.

          Usamos dispositivos VOIP da Cisco e Grandstream em qualquer lugar da minha rede corporativa.
          Com esses dispositivos, o SIP basicamente passa para o pfSense NAT, então não há tarefa com isso.

          A diferença é que os provedores de VOIP mudaram a porta SIP para a faixa de 30K. Devido às muitas chamadas falsas da Internet VOIP.

          No pfSense, apenas o RTP é encaminhado através do NAT.

          Organizamos os dispositivos em grupos para que as portas RTP não entrassem em conflito.
          Todas as outras configurações são desnecessárias, como também o pkg. proxy SIP no pfSense.

            @DaddyGo Queria ter ajudado mais.. Calma que estou aproveitando essa quarentena doida ai pra estudar, e tenho feito isso todo dia.
            Em breve vou dar uns pitacos em VOIP =)
            Abraço

            Obs: A primeira coisa que eu teria feito seria por o modem da ISP em bridge, mas você já havia sugerido isso lá em cima

              @mcury said in Voip conecta mas não sai audio:

              Com isso, já executamos um tópico apenas em inglês
              a maioria das sugestões foi o modo - bridge

                @DaddyGo É, isso vale para bastante coisa.
                Esse esquema de por o pfsense na DMZ do modem da provedora, já me trouxe problemas como:

                1 - IPv6 quando a provedora te fornece um /64 apenas, o track interface não funciona.
                2 - Os IPs que chegam na WAN do pfsense chegam mascarados por NAT impedindo assim um bloqueio por origem.
                2.1 - Logs de Firewall na WAN são inúteis.

                Pelo que me lembro, foram esses os problemas que tive até hoje com esse esquema.
                E acabou de entrar para minha lista, o problema de VOIP sem áudio..

                  VOIP é um animal estranho, os seus normativos estão a mudar constantemente
                  Nem ouso pensar em IPv6 com VOIP.
                  Basicamente, executamos uma conexão VPN dedicada sobre IPv4 na rede interna para VOIP

                  e para o mundo todo, através de uma conexão Express VPN pago ao provedor SIP para mascarar nossos endereços IP públicos fixos.

                    Guys, I managed to make it work.
                    Without DMZ, direct public ip on PFsense.

                    But I have the following problem, I can make a normal call, but when I hang up I can only call again after about 20 seconds, or when I kill the Pfsense table.

                    Any tips?

                        hi,

                        Super ✋
                        @rafamello "I can only call again after about 20 seconds"

                        I say my past experience:

                        This can happen with many cloud-based VOIP services
                        Although 20 sec seems a bit much.
                        This value is usually between 3 and 6s.

                        What is the ping of the SIP server? (in ms)

                        Netgate:
                        A keep-alive or re-registration on the phone set for 20-30 seconds or so can also help, and is often a better solution.

                          I've done everything, it works when the consultation, with every call that ends, I have to wait about 30 seconds for more.

                          The link procedures have all been tested with various combinations.

                            what SIP error code does the device show if you make a call immediately?

                            https://en.wikipedia.org/wiki/List_of_SIP_response_codes

                            ++++edit:
                            what you describe above may occur when the connection to the SIP provider remains active:

                            -this can be a device setting
                            -and a number of features can be configured, such as in the SIP provider's customer service management interface (web or other)

                                  Rafa, observando a sua captura, deu a entender que a primeira conexão, a que funcionou, a porta de destino era apenas a 5060.
                                  Na captura abaixo, eu pude observar diversas portas de destino, e pelo que pesquisei, o SIP não utiliza portas altas.
                                  Eu realmente não sei se o problema é esse pois nunca configurei uma rede assim, mas acho que pode ser alguma coisa com o NAT conforme descrito anteriormente no site que sugeri.

                                  Tenta configurar um NAT estático na VLAN de origem para fora, para que a porta de origem não seja reescrita.
                                  Seria mais ou menos assim:

                                  Disable source port rewriting

                                  By default pfSense® software rewrites the source port on all outbound traffic. This is necessary for proper NAT in some circumstances such as having multiple SIP phones behind a single public IP registering to a single external PBX. With a minority of providers, rewriting the source port of RTP can cause one way audio. In that case, setup manual outbound NAT and Static Port on all UDP traffic potentially with the exclusion of UDP 5060.

                                  Imagem de um exemplo:
                                  92c1ebcc-03ef-43b9-9474-5de339363c1d-image.png
                                  ca68d3f7-0e69-49fa-aad8-ca81950e7a40-image.png

                                  Na imagem acima, o IP 192.168.255.250 sai com NAT estático, não tendo sua porta de origem randomizada, ou sofrendo PAT (port address translation).

                                  Caso isso não funcione, tem uma outra observação que você pode tentar, que é instalar o aplicativo abaixo, ele está lá na parte de programas para instalar no pfsense:

                                  Use the siproxd package

                                  The Siproxd package is used only for deployments with local phones and a remote PBX where rewriting the source port breaks the ability to connect because the service will not work with rewritten source ports. In this very specific circumstance the siproxd package enables multiple phones to connect to a single outside server with a static source port of 5060.

                                  Do not use this package if the PBX is local. Only use it if the upstream PBX strictly requires all phones to have a source port of 5060.

                                  As informações foram tiradas do tutorial lá no site do pfsense: https://docs.netgate.com/pfsense/en/latest/nat/configuring-nat-for-voip-phones.html

                                  Avisa ai se tiver sucesso

                                    Tudo certo?

                                    Já tinha a regra criada, o que fiz foi retirar a range de portas que a "OPERADORA" para utilizar ... ficou assim :
                                    Screenshot_1.png

                                    Funcionando certinho, mas tem uma questão que não impede o funcionamento mas não condiz com o pensamento de portabilidade de usar em qualquer lugar.

                                    Screenshot_4.png

                                    Só Funciona se o IP da internet local estiver marcado ali e o Permitir reescrever IP estiver marcado.

                                    Alguma dica?

                                      @rafamello Desculpe, não entendi o que você quis dizer com: "Funcionando certinho, mas tem uma questão que não impede o funcionamento mas não condiz com o pensamento de portabilidade de usar em qualquer lugar."

                                      Os usuários estão utilizando de outras subnets?
                                      Ou você teria mais de um IP público?

                                        @mcury, eu tirei as portas nas configurações do NAT como na imagem anterior, funcionou... Só que tem essa opção de deixar o IP Externo configurado no app, se eu tirar ele, não funciona.

                                        Deveria funcionar sem nada marcado ali, tipo... se o usuário sair da empresa vai funcionar na internet que ele está automaticamente.

                                          @rafamello Entendi, bem, a configuração do NAT seria para redes que estão atrás do pfsense.
                                          Quando o usuário está na rua, ele não estará atrás do pfsense, ele estará se conectando diretamente ao IPBX através do 3g ou de uma rede wifi qualquer, sem relação nenhuma com a sua empresa.

                                          Como eu não conheço esse aplicativo, e tenho pouca experiência com VOIP, eu recomendaria uma conexão VPN, mas de repente existam outras opções que eu desconheço, vale a pena pesquisar melhor.

                                          Eu faria da seguinte maneira:

                                          Configure uma VPN no pfsense, acho que a Openvpn seria melhor que o IPsec nesse caso, pela maior facilidade de configurar o celular dos clientes.

                                          Eu configuraria um SPLIT tunnel, ou seja, quando o cliente se conecta a VPN, você roteia as conexões para o IPBX pelo túnel, as outras conexões do cliente não utilizariam a VPN assim não usando a banda de internet da empresa.
                                          Crie regras de NAT conforme descrito anteriormente, com NAT estático de saída para os usuários da VPN.

                                          Dessa forma, quando o cliente precisar usar o VOIP, ele precisa se conectar a VPN da empresa.
                                          Ele não vai precisar alterar o IP público no APP, pois ele estará usando o IP da WAN da empresa.

                                          dead on arrival, nowhere to be found.

                                            até agora você não disse que existe um uso em duas etapas
                                            (rede corporativa / é acesso pessoal à internet Wi-Fi, 4G, etc.)

                                            que tipo de dispositivos são esses?
                                            você diz que eles são portáteis ... ?!

                                            nós os usamos em uma versão portátil
                                            https://www.zoiper.com/

                                            uma solução perfeita se você precisar de um recurso de telefone comercial e se quiser usar uma conta SIP em casa
                                            (ao mesmo tempo)

                                            Cats bury it so they can't see it!
                                            (You know what I mean if you have a cat)
