Custom context - how is it suppose to work

Ok… Installed the custom context modelu.

Here is what I’m trying to do

extentions 1111 and 2222, trunk 1111111

extentions 3333 and 4444, trunk 4444444

I want 1111 to be able to call 2222 and also to use trunk 1111111 for outgoing
I do not want either 1111 or 2222 to be able to access 4444444 or to be able to call 3333 or 4444

So far I managed to prevent the trunk usage, but still is able to call between 2 contexts. Not sure what do I need to do?

I have the same problem. Please tell us what should we do.
Look forward to hearing from you soon.
