This is the log from a Max1800 calling to a Pipeline, DSS1 (German Telekom) BRI on both sides,
switchtype configured as JAPAN on the Pipeline (local Profiles, no RADIUS) :

Aug 14 12:16:15 max ASCEND: slot 5 port 2, Outgoing Call, 9-5551111
Aug 14 12:16:20 max ASCEND: slot 0 port 0, line 8, channel 2, Incoming Call, 7615551111
Aug 14 12:16:20 max ASCEND: slot 5 port 3, Assigned to port, 7615551111
Aug 14 12:16:22 max ASCEND: slot 5 port 3, line 8, channel 2, Call Connected, 7615551111
Aug 14 12:16:22 max ASCEND: call 96 AN slot 5 port 3 64K 5552222
Aug 14 12:16:23 max ASCEND: call 95 CL 0K   c=2 p=2
Aug 14 12:16:23 max ASCEND: slot 0 port 0, line 8, channel 1, No Connection, Cause code 016
Aug 14 12:16:23 max ASCEND: slot 5 port 2, Call Terminated
Aug 14 12:16:27 max ASCEND: slot 5 port 3, LAN session up, customer

As you see, the Pipeline calls back immediately after CLID, and the call is terminated right in time to
prevent that "LAN Security Error" that would occur if you had configured NET3 or UK.

That "No Connection" makes me feel good about no B-Channel being used, but i wonder about
"Cause Code 016" <Normal Clearing>. So there is no charging, right ?!?

I did not find it in any release-note too, so what is the status now ?
