Brent,
just a thought, when one end hangs up, does the line prot on BRI goes down ?
If so, then the /32 route disappears and causes a change in topology.
However the dialer interface would remain up/up (spoofing) and so the /32
doesnt actually disappear.
I have seen this behaviour in few cases, check if this is affecting ur case.
