Ok here it is: I have an 81c that uses XLST. I am trying to figure out how to breakdown the NCOS/TGAR/XLST and see how the call flows from start to finish. For example if you sat down in front of my switch without knowing anything about it, and you seen a COS of "1-2-1" (NCOS-TGAR-XLST) programmed to a set, what steps would you go through to see what that phone is capable of doing? (I.E. Local only, long distance, etc.). Thanks in advance on this one.
