Trying to find out how to check and verify if pri is enable on a MICS.

if there is a T1 card, you can check to see if it is programmed as PRI. Someone else may have a better way.

You could have the PRI Code enabled but not programmed.
So just checking to see if it is programmed may not tell you properly.
Go into the Hardware for one of your trunk cards.
Then press CHANGE and go through your options and see if PRI is one of the options to pick from.
