with broadcast the conf is not needed-when MOH is given on a multigroup switch-the TN in the group is used, so a set in group 0 or a trunk in rt 0 will use TN 4 0 0 3---a set or trunk in group 2 will use tn 84 0 9 6. I think you probably have a bad trk TN or connection on one of those 5 MOH connections.So if that set 72 0 8 10 put the call on hold, tn 84 0 9 6 was used as the MOH connection.There is a way of direct connecting using a maint. set---but if you are not familar with that---get a set in that group----loops 64-95 and dial the access code for the MOH---you will stay within your group and use that tn 84 0 9 6. The same procedure could be used for testing the other TN's---from sets in that network group.
