Why is the internal call not going through?

Question

Asterisk

I set up an asterisk, it calls from outside to internal and from internal to outside. But it doesn't ring inside. Dialplan error. I've tried everything, I can't catch it.
I call from 100 to 111
Here is the error log

<--- Transmitting (NAT) to 92.*.*.69:38091 --->
