No, both lines were call backs in my post. Both times, R5 called R2 (I
was doing multiple pings on R5), and R5 called back. See the bottom of
my post.
My equipment requires dual spids, and dual dialer maps, maybe that's the
difference with you experience.
Also `isdn fast-rollover-delay 1` has greatly helped. I've had dialer
fights between routers (multiple calls, multiple time-outs, very
astable), before I learned to use the rollover command. I think it's
just dependant on my equipment, but it wouldn't hurt in a normal config.

If you have a hard time remembering this, it's in the
doc cd.

Also, be careful with the multilink. I don't guess
you will have enough traffic to bring up the second
line but if you did, the server would never call you
back.
