Do both of your spids show active when you "show isdn stat"?

Subject: ISDN / ospf demand interface question (long)
Listers-
I am playing with ospf demand circuits over isdn and I am having mixed
results at best. I am just not seeing why this config (below) is not
working. The router will connect over a single B channel but the second
B channel is never activated and the connection stays up. From the
debug of R1, it appears that R1 doesn't try to make a call on using the
first dialer map to the first B channel of R2. I have played with the
dialer load-threshold values but the behavior doesn't change. Any ideas
would be appreciated.
R1 debug (captured when the first channel is up and a load is placed on
the link)
