On the Adminsitration page, under the Properties section / Settings / Robinson lists Robinson lists a.k.a blacklists can be created. Blacklists prevent the dialer from dialing the blacklisted phone numbers.
There are two types of blacklists:
- Global blacklists (affects all current and future outgoing projects).
- Project blacklists (phone numbers that are blacklisted in a project can still be dialed from other projects).
