Installed from scratch but can´t call extensions

I have just followed the scratch install instructions
http://astguiclient.sourceforge.net/scr ... stall.html
but when I try to call from one extension to another it doesn´t work.
Is this behaviour OK?
I have tested SIP extensions and trunks and they register fine
