Hello, I am asking for help about setting up some rules.
Say if I have two groups of extensions, Sales team 1000, 1001 and 1002. Accountant teams 1003, 1004 and 1005. I want sales team can call internally but cannot call to accountant team’s extensions and vice versa. How do I achieve that to separate two groups?
I google and think Custom contexts is the answer. But I don’t know how to use it after the installation.
