Decoding Q931 Facility Messages

First of all, forgive me for the newby question. :-)

Do any of you know how to interpret the "Facility i = " field in the
output
of "debug isdn q931" ? I'm trying to debug some QSIG call transfer and
path
replacement stuff and I can't figure out what I'm even looking at.

As an example (taken from a Cisco router):

*Nov 10 19:12:56.031: ISDN Se0/0/0:23 Q931: TX -> FACILITY pd = 8
callref =
0x0022
Facility i =
0x9FAA068001008201008B0100A11F02020A0002010C30160A0101A00EA5090A010412043738
32300A01030A0100

How do I figure out which q931 message that actually is? It is most
likely a
QSIG call transfer message, but I need to know for sure, and I also
need to
figure out which messages in my logs are QSIG path replacement
messages.

Any ideas?

Thanks!
John
