In a twin cabinet configuration, a set will always choose a line in its own cabinet over free ones in the other. The only way to fix this would be to put the co lines in the master cabinet in one group (TRG1 for example) and put all the trunks in the slave cabinet into TRG2. Then go into program 103 and set the outbound CO group selection sequence to '12'
This will force sets in the slave cabinet to choose lines in tht master first, and then the slave.
This is a simplistic trunk group set up, but the point is clear. You could make a more elaborate one if you have other groups that require individual selection.
Have fun.
