Call Scenarios and Applications
12.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.
