20. ASAI Messaging Scenarios —
VDN Return Destination
This is a scenario where a call to a vector is routed using Adjunct Routing to an 
external destination. The host then drops the external destination and the call is 
delivered to the Return Destination for further vector processing. The scenario 
assumes that the call is being monitored by the ASAI host and that the Return 
Destination is VDN 77777.
