said by DBOD:Thanks for the tip. My router has CC CIDR block to be allowed so that was not the problem. I have specific rules within asterisk to allow hosts that I tell it to allow as an incoming carrier. Before it was alpha1 to 9. I am now up to 20.
People need to be aware that they increased the number of servers about three weeks ago. I also had to add them to my router to get it to work but I fortunately spotted this on the day they added them. They can add at any time. It is best if you permit the entire range of ip address 0-255. Unfortunately my router won't let me specify a range and I have to add them individually.
