Configure Asterisk

I am a computer science student. I am learning about asterisk. I installed goautodial ce-2.1-final. It contains: Asterisk 1.4.39.1.
My newly installed system is unable to make outgoing calls.
Here is the configurations I think necessary. Please tell me what changes do I make?

I just noticed
sip show peers ->
tintoring/7824454609 192.198.87.44 N 5060 UNREACHABLE
may be this is the cause. How to resolve it?

Unreachable means that it failed to respond to OPTIONS request, not even with a rejection. The fix is to fix whatever is causing it not respond. This could be many things, in many places.

In the relatively unlikely event that it isn’t responding because it has buggy handing of unknown methods, you could try qualify=no, which turns off this test.

If it is responding, but extremely late, you will probably need to fix this but it is possible to set qualify to an even longer time.

Incidentally, why are you starting to learn on a version of Asterisk that is past its maintenance end of life?
