Did this ever work?

Is the PRI up and configured to take that digit string?

What are the results of "show interface pri 1"?

What are the results of "debug isdn l2-formatted" when you place a call as described?

Also, nothing hugely glaringly obvious, but some cleanup:

• A2.05 is ancient. Upgrade the code to the latest extended maintenance release.
• I would enable IP routing and install a default route to your next hop, as follows

ip routing

ip route 0.0.0.0 0.0.0.0 192.168.147.190

​And this might be a good time to change your enable password.  🙂

Thanks for getting back to me - after i power cycled the box with this config - was able to connect calls -

Will take your advice and cleanup config and update release - thanks! again.
