hmm. I will try using dlsw+ to resolve media-translation issue because dlsw+ does it for you. I used dlsw+ for most of my projects and worked great without this problem. dlsw+ also has keepalive features that work with DDR & link failover, in your case, ISDN BRI.

Subject: RE: ISDN IRB Question
I did all that
bridge 1 route ip and
bridge irb
and still does not work
(it does not work only for ISDN, for frame relay
it works well)
This is what I got from
http://www.netcraftsmen.net/welcher/papers/irb.htm
Caution
Plan ahead, and watch out for encapsulations when
using BVI with mixed media. The defaults are the usual
Ethernet encapsulations. Thus Novell traffic routed to
the BVI to be put out the bridge group interfaces
might appear as novell_ether encapsulation, sometimes
referred to as "raw Ethernet". Think of this as what
crosses the connection to the "external bridge". If
there is a Token Ring or FDDI interface in the
bridge-group, the packet must receive
media-translation prior to being transmitted out that
interface. Translation alters the encapsulation to
"raw-Token" or "raw-FDDI", which may not be what we
want. One workaround might be to specify SNAP
encapsulation for the BVI. But then we do get SNAP out
any Ethernet interfaces.
I just wonder, if this is the case that happen
