3Com Impact

I now have two users that cannot connect via ISDN with 3Com Impacts; the
analog side of the Impact connects fine. All was working well until I
added OSPF to the PM3 (ComOS 3.5c6), and I think it was from that point
that they've not been able to connect. They are getting some error
message about remote end not answering.

One of the clients that cannot connect sent me a .gif screen capture of a
low level trace of the failure (he said he could not cut and paste from
the debug screen ???). I sent that .gif to support@livingston.com last
Friday, I think, so that may or may not have been looked at yet.

The final messages from this trace are below:

<trace>
......
I 08 Cause Len=2
80 coding standard CCITT
location user
d1 class invalid message
cause value 81
invalid call reference value
</trace>

Any clues on what this might be? I've got an Ascend P50 connecting with
two B channels just fine using OSPF to route a subnetted class C, but the
Impact won't connect. Glad to give more details as needed.
