Dear Support Person,
we have an Issabel installation (ver.:4/asterisk:16.7). We need to have some restrictions on some extensions, so that they can not call some other extensions. (for example, 101 should not be able to call 102, 103 and 104, but can call other extensions. the same example exits for some other extensions). We set this configuration using "Class of Service" and saved it. But it is not applied. meaning that it does not work.
However, when we disallow only one extension (for example 102) it works.
Would you kindly help us to implement this configuration?
