I want to use this value in AGIs - which are sometimes being run
directly from "originate" callse, so setting the CDR userfield isn't
that useful to me, but several previous answers on this thread suggested
"systemname" (which I wasn't aware of) and I think that is the solution
that I was looking for. 

Thanks to everyone who answered!
