Voip conecta mas não sai audio
-
Olá pessoal, tudo bem?
Estamos com um problema aqui na empresa, temos uma central IPBX na nuvem e o clientes internamente,
Fizemos a chamada normalmente mas não vem e nem vai o audio
Temos as portas 5060 liberadas na LAN e as portas RTP também liberadas na LAN, ambas UDP.
O modem tem uma DMZ para o Pfsense conforme imagem acima.
Já configuramos o IP publico direto no PFsense e também não funciona.
Existe algum passo a passo para esse tipo de configuração? Pois já testamos tudo e nada funciona, mas se retira de tra´s do Pfsense, funciona.

Boa tarde Meu Amigo,
São muito poucas as pessoas que falam português aqui no fórum
O problema ainda é que o modem ISP está na DMZ.
Na DMZ, apenas as portas estão livres, mas o endereço IP é NAT.Nesse sistema, você precisaria de um servidor STUN para obter resultados.
Ou melhor no modo bridge com seu modem ISP.
Cumps,
-
Perfeito.
Colocamos a Wan em PPPoe, mas também não funcionou...Pessoal do voip com todo seu "conhecimento" dizem que o problema está relacionado a stateful e assimentria IP.
Stateful creio que não seja a questão.
-
Atendemos muitos clientes com VOIP por trás do pfSense.
Sem qualquer problema...O SIP registra apenas a conexão
A RTP oferece as vozes em dois sentidosO SIP penetra até 2 NATs (passagem NAT)
o RTP deve ser controlado pelo encaminhamento de portatem um colega de língua portuguesa aqui no fórum
ele é muito bem preparado, vou mencionar o nome dele aqui, talvez ele pode ajudarola @mcury , já encontraste um problema de VOIP por trás do ISP / DMZ NAT + pfSense?
Obrigado,
-
@DaddyGo Opa, obrigado pela referência :)
Na verdade eu ainda não passei por isso, nas empresas que trabalhei, tinha uma equipe de voz que fazia isso e infelizmente eu não participei..
Eu estava acompanhando aqui vocês para aprender essa parte e me aperfeiçoar :)
Mas deu uma boa ideia, vou estudar essa parte de VOIP, SIP, STUN, conhecimento nunca é demais e ninguém pode tirar isso da gente né =) -
@DaddyGo
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 =)
AbraçoObs: 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
https://forum.netgate.com/topic/154886/voip-no-audioAbraço também

@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 VOIPe 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?

@rafamello Hey, check if this can help you:
https://docs.netgate.com/pfsense/en/latest/nat/configuring-nat-for-voip-phones.html -
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) -
Hello, follow or log a successful call and a negative one.

the support of the caputadora operator a connection and it was like this:
-
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:
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.
