I use Asterisk 220.127.116.11 .
I use it as sip proxy server.
I want to use one of register number in the asterisk and make call through the sip trunk and that sip trunk is no need to register or request register/auth message.
Just an IP address XX.XX.XX.XX and it can accept any invite message if you forward to him.
So, how can I configure the number, sip trunk ,and outgoing route in this case ..
what is the context in this case .
In simply , that mean I make a call from a number in asterisk and route this outgoing call to an external IP address.(make outgoing call)
Please advice detailed.
