we have a point-to-point T1 between two offices that shows our ext and name when we call each other. Tech A inadvertently changed this route on my end so that when we call far end they see our seven digit office number (instead of our ext). Tech B says he can correct this but only after hours. However, I'm not sure vendor even clearly explained to tech B what the problem is and I need to know if this really can't be corrected until after hours. I'm trying to figure out how to do it myself but cannot. Is this a complicated procedure? We have each other programmed as TSCs in LD 87. If this can be done fairly easily I'd like to just do it myself. Many thanks in advance.
