Most Definity systems have a "Hunt to" place when u do "change station" xxxxx. U can have the station ring over to the next station, and then have a 'hunt to' the next station. Course it can cause problems if u want the calls to go else where for the intermediate station. The number of cover path points changed with the newer versions of the Definity but I don't remember the number. In the newer versions u can actually change the number of times it will ring on each point, which use to be a system wide setting.
