I just upgraded to a opt 81C rls 25.40. My dorm room sets are TLD to make them use auth codes. They are also able to dial 1800 without using auth code when using copper trunks. When we cut to PRI service they cant dial 1800 with out the auth codes. Something is different about the PRI but I cant find it. The PRI is programmed as 2- way DID. Does anyone know why I am restricted when I use the PRI. The only change in programming was the route # in the RLB.
