Configuring call authority control
To configure call authority control, you can assign subscribers to a subscriber group, then bind the group, which has permit or deny authority configured, to a voice entity.
When a subscriber originates a call that matches the voice entity, the system compares the calling number with each number in the bound subscriber group. If a match is found, the calling is permitted or denied according to the authority (permit or deny) configured; otherwise, the system finds the next matching voice entity until the call is permitted or denied.
