FYI….you can specify rules for blacklisting via the Pirate Porthole. For example, to blacklist all calls from 212-555 just enter “1212555” or “1212555*” into the blacklist (the star is equivalent to a blank). We have not generalized this to accept more flexible regex because we have not seen the need, but if you think there is helpful use-case for more flexible blacklist patterns, we are very interested.
ps. here is a tutorial that shows us using blacklists with patterns: https://jollyrogertelephone.com/tutorials/#TutNewUser5
