Extconfig.conf missing?

This is my output. I am trying to diagnose why I can not call between extensions. All I get is “The person at extension xxxx is unavailable”. I know there are a few others having this same problem. I am using Asterisk@home. I have had this problem with 1.5 and now trying beta 2.3

I do not know exactly what extconfig.conf is, put if this file is the overall config for extensions then I could see the problem exists there for calling extensions.

[root@asterisk1 ~]#
[root@asterisk1 ~]# asterisk -vvvvr
