Everytime I try to turn up a trunk either PRI or T1, I fail. After spending hours for troubleshooing, I usualy endup openning a case with Cisco TAC and have their help. I was never able to do it alone. I am tired of it and need you help to learn how to do it. Could you please advise?
What is the best document for turnning up ane troubleshooting a PRI and T1 trunk
