*ISDN spider-sense goes off*

Are you sure about this?  I can't cite specific references, but a 
facility message outside the context of a call (including non-call 
associated signaling connections) seems like it would be a blatant 
protocol violation.

I'll tell you what, I haven't been able to figure which specs to look 
at for this.  If you (or someone else that knows which ones we're 
referring to) can give me an idea of which documents to look at, I'll 
go through them to see if I can offer another opinion on the matter 
(ETSI references, URLs, etc, ITU-T doc numbers, anything).
