How to isolate extensions

[miltonviziak]

Hi there i need some help

I have some extensions created, like, 1000,1001,1003 and 2000,2001,2003. The extensions are on the same domain.
Is there any way where extensions 1001 and 1002 only call 1000 and 1000 can I call any extension 1XXX and 1XXX extensions cannot call any 2XXX ?

I tried to use dialplan in fusionpbx to isolate the extensions, but it didn't work and I don't know where it could be wrong, so the apparently easiest method is to use different domains.

Have you tried using the dial plan on the phone itself. We used to run a multi Tennent asterisk system and we isolated users by jailing them in the phone dial plan.

I didn't get to try that.
the customer's cpe is a fiberhome ont with fxs port.

Could use contexts or dial plans to do this in fusionpbx instead of many domains ?
