Blacklist with *30

I want to use the feature code *30.

the system say:

Please enter the number to be blacklisted. If this is correct press 1. If I press one it say invalid option, if I enter phone number, nothing happen, if I do nothing after 69sec it say, Sorry your having problem, good bye.

Is this a new bug or I have wrong configuration somewhere?

Thanks for your help. :slight_smile: :slight_smile:
