Stopping extensions ringing each other?

General Help
1

Just wondering if anybody would know a way of stopping extensions ringing each other through FreePBX? I am using FreePBX 2.3, they are internal sip extensions registered to the same Asterisk box.

I can go into the config files and code it but am reluctant to do it as it would disable some of the functionality in FreePBX. Thanks for any help.

Hi,
there is a ‘blacklist’ module - I’ve never used it, but possibly you could blacklist the unwanted extensions from each phone, then change or remove the blacklist feature codes to stop users modifying things?

if you mean separate internal extensions so that they are in different contexts (a form of multi-tenant so to speak) then no, not at this time.
