Week 5 and week 6 – Asterisk* Lab

Here You can see that the address is set and that the Ports are now active.

And I can get a line for 3 seconds Using my windows phone but it doesn’t stay connected. I have now been working on getting tested with Chas from class

This is the coding that I used to set up my Config line. I am still working on the configuration setup.This was taken out of the Red Hat Book.
