Robert, As far as I understand from your trace you can not make a call in siemens -> sipx directions. Looking at you trace one can see, that your Mediant 1000 gateway sends Cancel with "Reason: Q.850 ;cause=102" in 4 seconds after Invite. Q.850 says that cause 102 is related to RES timer expiry. I'm not sure what "RES timer" is.... Looks like Siemens sends "disconnect" with cause 102. And there is something wrong in the siemens-mediant isdn link (is it pri?).
If I were you, I would increase a debug level on the mediant to 5. Then point mediant to a syslog server. Make a call. Try to analyze syslog file. (You can view syslog messages from the mediant web interface, but my experience is that web interface does not show them well...). I can try to take a look at your syslog file...
