External Call to Lookahead Interflow VDN
This scenario shows the call flow for an incoming ISDN PRI call to VDN 5008 that 
looks-ahead to VDN 1111 on Switch B (see Figure B-35). The first lookahead 
interflow attempt is denied by Switch B. The second lookahead interflow attempt 
is accepted by Switch B and the call is delivered to and answered by extension
