We have specific number that rings into our PRI to one of our DID numbers about three or four times a week. When the person answers, no one is there. The user has asked if we can block that number since it's just and annoyance. I tried setting up a Route Pattern but that probably isn't the answer since it is based on the called number not the calling number. I do have the calling number and would like to block it.
Thanks in advance for your assistance.
