Yes. A withheld number is where a caller purposely blocks their number from being released when making an outgoing call. Choose to Refuse will still be able to bar any calls made from that number using the ‘**’ facility. However, you will not be able to see what the number was within your list. Whenever a withheld number is held in the list, when reviewing your number list you will hear a message advising ‘a caller who withheld their number was barred on etc’.
