Eu tenho um caso particular em que operadora (não provedor) me atende sem precisar se registrar. No lado do portador, os números têm um IP associado que é usado para encaminhar qualquer chamada.
Para chamada de saída, eu só preciso empurrar a chamada para o servidor transportadora (sem registro).
Para enviar chamadas de saída, eu tenho um Cisco SPA504G, disposto a comprar vários outros se eu puder encontrar uma solução de trabalho.
Depois de testar muitas configurações, posso fazer chamadas de saída ou de entrada com a alteração das configurações, mas não consigo ter as duas coisas funcionando ao mesmo tempo.
Pelo que vi, o "outcall" no sip.conf é usado em chamadas de entrada que eu não quero. Eu tentei muitas configurações com dicas on-line / howto, mas o meu caso parece um pouco particular.
Por favor, encontre abaixo minha configuração e me ajude a resolver este problema:)

Tenho certeza de que existe uma solução, provavelmente um passo à frente;)
