I agree, we probably don't need to state it esplicitely.

We have already have REQ 12 stating that
	 Any communication performed as a result of the execution of a
CCBS/CCNR request should be distinguishable from regular communications.

So,  all terminating call are "distinguishable" and any policy a network
might have could be easily based on this, without further requirements.
Other views ?
