Which numbers should be blocked?
I want to block following types of numbers in my extensions.conf like
the premium number in Taiwan:
exten => _90204X.,1,Congestion
Since I have a DID in USA, I need to block these numbers in USA, as well
all emergency numbers, but still let open free (???) service numbers.
Can you help me to compile such a list?
bye
Ronald
