Scenario.
Xtn 'A' is 29904 at location 700, Meridian
Xtn 'B' is 5505, at another location, 791, Meridian
Xtn 'C' is 6606, Centrex
DPO R 55 31 1 ISRM-C 10 *1#*19*U#*50*70029904#7565505
DPI R 55 31 1 NAM *1#*50*6606#
DPI R 55 31 5 CCM *1#*50*6606#
'B' is CFWD to 'C'. dialled by 'A' and is a success.
Now, Xtn 'B' is 3651, at location 791 and is Cisco IPT.
It has a CFWD to 771 318444.
This returns a *40B* and fails.
DPO R 55 27 1 ISRM-C 10 *1#*19*U#*50*70029904#7913651
DPI R 55 27 1 NAM *40B*771318444#
DPO R 55 27 4 CRM 30

My original understanding was that the *40B* was 'information' saying "There is a Divert Immediate C party address" and an instruction to the 'A' party switch to re-initiate the call to C party address.
However, when it 'works' I don't see a *40B*, I only see one when it Fails !!
What exactly does the *40B* tell me ?
The BTNR 188 document doesn't refer to the 'B', only the 40.
Are there any 'other' traces that can be put on, at the Meridian, on a DPNSS link, that will provide a better 'clue' as to why I encounter fails ??
