I have an Opt 81C rls 4.5 and I need to point 911 to a regional dispatch center number which is a 10 digit number. I have tried creating a RLi and a DMI to strip the 3 digits and insert a 10 digit number. however, when I try to call 911 using the new RLI/DMI I get a fast busy. I have changed the SPN 911 to the new RLI but no avail. Anyone have any suggestions?
