I am currently using AsteriskNow which include this FreePBX.
Now I am looking solution how to restrict calls.
I have extension/extension groups 100 000 - 199 999 and 200 000 - 299 999. How I can make rule that only allow internal call between 100 000 - 199 999 extensions but not can’t make call 200 000 - 299 999?
I have understand that I need to make modifications in sip_custom.conf and extensions_custom.conf?
I have found those configuration files under /etc/asterisk/ but it’s only way to edit those using SSH? I have also found that there should be something file editor in FreePBX?
