Q931 Translation of a Dropped PSTN Call

[blobberdog]

Hello,

We had 3 dropped calls when making and receiving calls over an ISDN30 Circuit.

I searched in the Q931 Translator and dicovered one of the calls. Below is some of the output which may indicate (to the trained eye) why the call was dropped.
