Can't make calls

Hi,
I had aah installed on my computer, so i removed every folder I can find named asterisk and then I installed trixbox on top of it.
Eveything seems ok, except that I can't make any calls at all. I can't call internal numbers or external numbers.
I tried to reinstall it twice now, but it still doesn't work. I cannot format my computer because I need the services it is running.
I installed it from the tar.gz file. Can anyone help?
Below are the logs when I try to make calls:
