	Not handy.  I've not tried to detangle the q931 data (yet).

	I had hoped that there was something as part of 8824 that
assisted in capturing this, but again, I know vendors can be strange.

	The IOS running on the device is 15.X not the 12.x reported by the UA
header.

My setup is

Nortel <- T1 w/PRI Signaling -> Cisco 2851 <-> Ethernet/SIP <-> Asterisk

I'll do some more poking for the docs and see if I can find the app/q931
documented someplace.
