The Pri is working,and is used for outgoing(PriA)But when I went into Terminals & Sets/ Line access/Line assignments/Show line,the target lines disappeared from every set & fax that had target lines assigned to them.
While the system was in this situation,they were still able to call out and calls did go to reception on their main line via the Intercom.
The Rec'd # under Lines (4-DIDGETS) for the target lines was still intact through all this and I simply had to reassign all the target lines to the sets and fax machines.I hope this info helps to try and figure out what happened here...Mike
