10 loop start co lines on controller (copper) getting stuck in "talking" mode when I go to show status. Having to re-boot controller to fix. Any ideas?

I'd check my trunk circuit descriptor tables, first.

The general issue that you're having is called "supervision" and the most common cause of supervision problems is that the controller expects a more definite signal that the other party has hung up. Line voltages and polarity can sometimes affect supervision.

Thanks. Trunk descripters are ok, I'll get a meter on the lines.

Make sure the LEC or who ever is supplying dial tone is providing CPC. If not, the trunks will stay up forever.
