I cross-posted your question to comp.dcom.telecom, and got this reply
from 
Michael_Perka@NeXT.COM :

The interactions of the Calling Number Delivery (CND) CLASS service with 
other services such as Custom Calling are noted in the Bellcore Technical
Reference TR-TSY-000031, "CLASS Feature: Calling Number Delivery".

Under section 3.8, Interactions:

"A. Call Waiting

	CND data should not be transmitted duing of after a Call Waiting
	(CW) tone.  Similarly, CND data should not be transmitted during
	or after any switchhook flashes that may occur in response to the
	CW tone.  Also, CND should not occur during ringback that results
	from the customer going on-hook in response to a CW tone."

Subsections B through J describe interactions with Multiparty Lines, Three-
Way Calling, various types of call forwarding, Distinctive Ringing, Auto
Callback/Recall, and Calling Number Delivery Blocking.

Ordering info for this TR has already appeared in Telecom-Digest.

Telecom-Digest is available as comp.dcom.telecom.
